Super Smash Bros. Brawl (大乱闘スマッシュブラザーズX Dairantō Smash Brothers X?, lit. "Great Melee Smash Brothers X") is the third installment in the Super Smash Bros. series of fighting games, developed by Sora Ltd. and published by Nintendo for the Wii. It was released in North America on March 9, 2008. Sonic the Hedgehog appears in the game as an unlockable playable character. Sonic is the fastest character in the game, even beating out prior fastest Smash Bros. character, Captain Falcon. He is one of the two third-party characters that were added to the game, the other character being Solid Snake.
Sonic is the fastest character in the game, and this allows him to use his dash attack repeatedly and quickly. This attribute, and many other moves, allows him to quickly rack up damage and then use one of his killing moves to finish the opponent. However, these attacks are difficult to land and are relatively weak. His aerials can be used to juggle opponents with the right timing and skill, allowing for many attack possibilities. His down aerial is a Stall-Then-Fall, which means that if he misses, he will have a long landing lag or will self-destruct (SD); this, however, will not occur if used at a certain height. His standard special, Homing Attack, locks on to opponents within a set radius, can be used to hinder opponents’ recoveries, and can be used infinitely under some stages to stall. His side special, Spin Dash, can give some horizontal movement if "up" is hit during the beginning of the move. His down special, Spin Charge, causes him to rev in one place (not in the air though). This move can be charged by rapidly hitting the special attack button and will be activated when "down" is released. His up special, Spring Jump, behaves differently depending on whether it is used in the air or on the ground. If used on the ground, the spring will remain for a few seconds, allowing anyone to use it, including the Sonic that spawned it. This means that he can use two Spring Jumps to cover a large amount of vertical distance. If used in the air, however, the spring will simply fall and act like a projectile. Using the Homing Attack and Spin Dash for horizontal recovery and the Spring Jump for vertical recovery, Sonic has very good recovery options. His final smash, Super Sonic, causes him to harness the power of the Chaos Emeralds to transform into Super Sonic, granting him invulnerability and flight, damaging anything in his path.
However, Sonic does have his weaknesses. He has low priority on most attacks, high startup and/or cooldown lag on his smash attacks, small hitboxes (range), and minimal means to KO. Projectiles hamper his approach, making him a somewhat easy character to defend against and to predict. He also lacks his own true projectile. Plus, if an opponent grabs and releases Sonic during his Spring Jump, he won't be able to use any specials and simply falls.
Sonic's many pros and cons cause him to currently be middle tier on the current SBR tier list, placing 22 out of a total 38, right in the middle of D tier.
The FINAL, Final BattleThe FINAL, Final Battle is the forty-first and final event match in Super Smash Bros. Brawl. In this final event match, The player is pitted against Snake, Sonic, and an supersized Mario. Each character has two lives. Its name is a joke because the event before it is called "The Final Battle." The event is won by defeating all three opponents.
Standard Special Move
In Super Smash Bros. Brawl, the Homing Attack appears as Sonic's standard special move. When used, he curls up, rising into the air, then homes in on the opponent closest to him. This move can also be used an unlimited amount of times in the air, thus allowing him to recover if opponents try to edge-guard him. If the Homing Attack is used when no opponent is nearby, Sonic dashes forward at a downward diagonal angle. If Sonic does not hit anybody with it and hits the ground instead, he will stall for a second, leaving him open for attacks in that time. Pressing "A" while Sonic is rising into the air sets the move off early. It also possesses an unusual quality that it tries to hit the opponent's side facing away from Sonic by traveling over them. This property means that it only hits effectively when the opponent is moving away from him on the ground, or traveling towards them in the air, making it effective at recovery gimping, and, combined with his naturally good recovery, gives Sonic a large edge-guarding potential, allowing him to be prepared for an opponent's attempt to recover.
It should be noted that the homing attack can be used to stall indefinitely and/or travel underneath stages by jumping into the ceiling of an impenetrable platform, then using this ability to ricochet off of it at will. When the player is about to use Homing Attack, he must tap the control stick left or right, depending on the way he wants to go, and then press neutral B. Sonic will change his direction, and attempt to home onto an enemy in that direction, or, if there is no enemy in range, dash downwards at a diagonal angle.
Side Special Move
Spin Dash is Sonic the Hedgehog's side special move in Super Smash Bros. Brawl. A chargeable move similar to Rollout, it also makes Sonic hop when it initiates. This move can give more horizontal recovery than Spin Charge. Both attacks move approximately the same once on the ground, and the direction can be changed once moving. Spin Dash is slightly stronger than Yoshi's Egg Roll, as Yoshi's Egg Roll breaks upon impact with projectiles that cause flinching, or well timed attacks. Spin Dash simply stops in function, and cancels out any damage. If the Spin Dash collides with the Egg Roll, both attacks are negated. Spin Dash can also destroy medium projectiles during the hop.
This Spin Dash is based on the Spin Dash that originated in Sonic the Hedgehog CD, where the player can build up speed for the Spin Dash just by holding the buttons, instead of rapidly tapping them. However, Sonic doesn't automatically jump when he dashes off nor can he change his direction at will.
Up Special Move
Spring Jump is Sonic's up special move in Super Smash Bros. Brawl, which acts as a personalized spring, causing a spring from the Sonic series to immediately appear underneath him, shooting Sonic up a great vertical distance. When used on the ground, the spring remains in place for a while, allowing other characters to use it too. If this move is used in the air, the spring falls downwards, acting similar to a projectile, dealing minimal damage and knockback, making it effective for edge-guarding. After using this move, Sonic still retains the ability to use normal aerial attacks and air dodges, but will be unable to use special moves until he touches the ground. Additionally, this move does not allow Sonic "snap" to any ledges onstage (I.E. auto-sweet spot) until he is finished gaining vertical distance, making it dangerous for recovery if Sonic goes above a ledge and exposed to an edge-guarder. Barring any outside influence, the spring will remain on the ground long enough for Sonic to do three jumps off of, disappearing just as he makes his third jump. This move also has invincibility frames when beginning vertical ascent.
If Sonic bounces off a previously set spring, it doesn't count as his up special as long as he doesn't land on it immediately from his up special, so he can use Spring Jump immediately afterward, gaining a great deal of height, essentially two back-to-back up.
Down Special Move
Spin Charge is Sonic's down special move in Super Smash Bros. Brawl. It is similar to Spin Dash in both appearance and function, but it has the potential to move quite a bit faster. Charging the move is different than charging Spin Dash, as the player has to hold "down" on the D-Pad/Control Stick and rapidly press the special move button. Unlike the Spin Dash, Sonic does not hop on initiation of this move (done by releasing "down"). However, Sonic still retains the ability to change directions or jump. If the player releases the special button but continues to hold down, Sonic will stop spinning in place instead of unleashing the move, allowing for feint attacks. This move can also be used in the air, but only moves forward a small amount until it hits the ground, making it somewhat similar to Yoshi's Egg Roll. Spin Charge is slightly stronger than Yoshi's Egg Roll, as when Yoshi's Egg Roll comes into contact with projectiles which create impact, or well timed hits, it breaks. Spin Charge simply stops in function, and negates all damage.
The Spin Dash is a standard Sonic technique originating from Sonic the Hedgehog 2. It's controls, behavior and execution are almost exactly the same in Brawl as they were in said game, save the fact that it can change the direction of its roll much easier.
Both the Spin Dash (not the hop) and Spin Charge, when used in the air, can be cancelled into a shield or grab when landing, allowing for feints.
Final Smashes are the ultimate, most powerful special attacks in Super Smash Bros. Brawl. To use a Final Smash, the player must first break open a Smash Ball, a colorful item with the Smash Bros. insignia on it. If shattered, the player's eyes would become gold and multi-colored highlights would surround the player. Super Sonic, the Super State Sonic takes after obtaining all seven Chaos Emeralds, appears in Brawl as Sonic's Final Smash.
After activating the Final Smash, Sonic goes Super and now has the ability to fly around the stage at an incredible speed. The transformation lasts for about fifteen seconds, and while Sonic is transformed, he is completely invincible. He can't KO himself if he touches the edge of the screen, regardless of how far he's going, but if he turns back to normal while he's too far away to recover, he will be penalized with a self-destruct. Sonic can attack in this form just by ramming into opponents; the faster he's going, the more damage is dealt. Simply touching him while he is in his Super State even deals damage to the attacker. It is similar in function to Pikachu's Final Smash, Volt Tackle, except that it has better knock-back and control but cannot go through fall-through platforms like Volt Tackle can. If the move is being used under the Bridge of Eldin stage while the destructible section of the bridge is re-materializing, the move will end instantly. The move is also useful when Sonic is sent flying and is about to fall down a bottomless pit, as this prevents him from being KO'd and can break his fall. He will, however, still be in free fall if used after using Spring Jump.
- Neutral Attack - A left-handed punch, then a right-handed punch, then finally a side kick with the left leg. 7% damage (2% + 2% +3%).
- Dash Attack - Rolls into a ball to hit anyone in his way, similar to the Spin Attack that appears in most Sonic games. 6% damage.
- Strong Side - Stick out both of his feet, with both of his hands planted on the ground (appearance and knockback comparable to Pikachu's forward tilt in Melee). 11% damage, in two hits (4% + 7%).
- Strong Up - Kicks upward which hits three times (appearance comparable to Captain Falcon's up smash in Melee). Very minimal knockback. 14 damage if all three hits connect (3% + 4% + 7%).
- Strong Down - Foot sweep (appearance and knockback comparable to Sheik's down tilt in Melee). 6% damage. Moves him forward.
- Side Smash - Winds up his arm during the charge and attacks with a short-ranged punch and yells "GO!". It has a good knockback, has a fast start-up speed, little lag after, but the range isn't too impressive. 14-19% damage. Can be angled.
- Up Smash - Sonic does a short jump and hangs at its apex for a bit, doing a spin. Enemies that get hit are caught into this attack, and gets hit multiple times until the final hit, which does decent knockback (low knockback in relative to a smash attack's standard). The attack has a lot of priority. In addition, it can be performed almost instantaneously after running making it a very good combo starter. 8 consecutive hits, 14-19% damage (7% + 1%x6 + 4%). This attack can also spike.
- Down Smash - Spin Dashes back and forth over a short distance around him. It has good knockback, and very good range. 9-16% damage. Very similar to "Dizzy Spin" from Sonic the Fighters. In this case, however, he circles around his original location instead of his opponent. Like a smash attack, it was his strongest move.
- Ledge Attack - Spins in front. 8% damage.
- 100% Ledge Attack - Stick's out one foot then the other while on his back, two consecutive hits. 13% damage.
- Floor Attack - Quick foot sweep, hits both sides. 6% damage.
- Neutral Aerial - Spins in place. Properties are similar to the properties of the Sex Kick. 11% damage.
- Forward Aerial - Drills at the enemy head first rotating his body. Similar to Pikachu's forward air. 14% damage.
- Back Aerial - Kicks behind him (appearance and knockback comparable to Samus Aran's back air in Melee). One of Sonic's best killing moves. 13% damage.
- Up Aerial - A scissor kick. First he splits his legs apart and out (capable of hitting enemies a bit to his sides) doing no significant knockback. Then he kicks up, knocking his opponents up with significant knockback. 9% damage.
- Down Aerial - A Stall-Then-Fall aerial. Sonic stalls for a brief moment, then shoots downwards foot first. Appearance is comparable to Ganondorf's Wizard's Foot.
This attack does not continue downwards until landing (although it does go down very far before stopping). It has a good amount of lag when hitting the ground. When hitting a grounded opponent, the angle of knockback is similar to Captain Falcon's Falcon Kick. 8% damage.
Grabs and Throws
- Pummel - Knees the opponent. 3% damage.
- Forward Throw - Kicks the opponents upwards using a high kick. Can follow with up air juggles, but it can be heavily DI'd backwards. 2 consecutive hits, 9% damage (3% + 6%).
- Back Throw - Does spinning back flips while (and while holding the opponent) and slams them on the ground, sending them backwards with very little knockback. Appearance is similar to Pikachu's back throw in Melee. 8% damage.
- Up Throw - Tosses the opponent over him and then lands on his hands as if to do a push-up. His quills harden just before they make contact and the foe is pricked upwards and at an angle. 2 consecutive hits, 12% damage (3% + 9%).
- Down Throw - Throws them down and spins on them (similar to Jigglypuff's down throw but not quite the same), then knocks them a bit forward. Does a good amount of damage and has decent horizontal knockback. 4 hits, 8% damage (1%x3 + 5%).
Up: Does a front flip, then crosses his arms with his index finger pointing out while making a teasing clicking sound, landing into one of his signature poses.
Side: Runs in place, forming a figure-eight with his legs, while saying "You're too slow!" in a teasing manner. His complexion becomes more serious near the end.
Down: Says "C'mon, step it up!" while breakdancing.
- Collects the blue Chaos Emerald and poses with it while saying "Piece of cake!".
- Sprints off-screen then sprints back on-screen before giving a thumbs-up and saying "That was almost too easy!".
- He breakdances and then does a pose with his fist, saying "Let's do that again sometime!".
Each character in the game is playable in the game's story mode, Subspace Emissary. The main universe of Brawl, the World of Trophies, is where trophies are either pit to fight each other or destroyed if they destroy their "true nature". In the "Sonic Joins The Brawl" trailer, Sonic can be seen fighting the Subspace Army with Mario. Oddly, this never happens in the actual storyline; it is only possible to play as Sonic and Mario if you replay a level with Sonic and Mario. Sonic only appears in the Subspace Emissary once, when he attacks Tabuu, the leader of the Subspace Army and weakens him. This is most likely due to Sonic's late inclusion in the game and most of the Subspace Emissary being completed at that time.
His exact role is like this: After completing a large level called The Great Maze, whoever the player was controlling, sees Tabuu in the sky. He tries to turn the player's characters into trophies just like before by using his Off Waves. But before he can do so, a blue blur streaks through his wings twice. This breaks the wings and removing his ability to turn characters into Trophies. Then the blue light stops at the top of a small subspace mountain, and it is revealed to be Sonic. He then wags his finger, smiles and makes a clicking sound, similar to his up taunt. After this, Tabuu gets angry and then the boss battle starts. Sonic is, if added to the group to fight Tabuu, at this point playable. The player can go back and play as Sonic on any stage once they've beaten this mode.
Since the release of Smash Bros., fans of fights or unions between Sonic and Mario have requested that Sonic be in Smash Bros. games. However, it seemed highly unlikely due to the fact that Sega (Sonic's home company) rivaled Nintendo (Mario's home company). In 2002 an issue of Electronic Gaming Monthly claimed that Sonic (as well as Tails) could be unlocked in Super Smash Bros. Melee by defeating twenty or more Fighting Wire Frames in Cruel Melee, however, this was revealed to be an April Fools joke using a fake screenshot of the characters taken out of Sonic Adventure 2. This most likely made fans desire Sonic in a future game even more.
When Brawl was announced, Konami's Snake of Metal Gear fame was on the roster of playable characters as the first third-party game character to be included in the Smash Bros. series. The demand for Sonic increased greatly, and was added after Mario & Sonic at the Olympic Games was revealed to gamers (though being a complete surprise in itself may have made Sonic's chances in Brawl seem even more of a possibility). Ranking over old favorites in gaming like Mega Man (by Capcom), Cloud Strife (by Square Enix) and Pac-Man (by Namco), Sonic was the most asked for character in Super Smash Bros. Brawl.
Sonic's confirmation on the Smash Bros. DOJO! (Super Smash Bros. Brawl's official site) was on October 10, 2007 at the same day a special Nintendo conference was held. His confirmation caused a huge celebration from most if not all Sonic fans. Coincidentally, however, Brawl was delayed on almost the same date, which disappointed many fans. But Sonic's confirmation softened most if not all the blow for Sonic fans.
Even so, the smaller role he plays in the Subspace Emissary storyline than Snake does amongst other characters made fans feel cheapened in Sonic's inclusion, including repeated movesets, slightly poor music choice, recent character trophies over old ones (ex. Silver the Hedgehog and Jet the Hawk over Metal Sonic and Fang the Sniper), and some fans were disappointed to not have Ryan Drummond voice Sonic instead of Jason Griffith, despite Rouge the Bat's former voice actor Lani Minella voicing Brawler Pit, Lucas, and Assist Trophy character Lyn. However, since Jason Griffith was his voice at the time, it seems implausible that Ryan Drummond would have even been considered.
Many people were pleased with the game and its gameplay. It has gotten a perfect score on almost every site that rated it. It is also the seventh game to get a 40 out of 40 in Famitsu.
How to unlock Sonic
- Complete the Subspace Emissary on any difficulty (Sonic will be automatically unlocked).
- Play 300 Matches of Brawl (after doing so, the player must defeat Sonic in a 1 stock battle. If the player fails the first time, he/she would just have to play another match to try again).
- Complete Classic Mode with ten different characters on any difficulty (after doing so, the must defeat Sonic in a 1 stock battle. If the player fails the first time, he/she would have to go through Classic again or play another match).

Super Smash Bros. Brawl has up to 41 stages from up to twenty various game franchises (including the Sonic the Hedgehog franchise as well), with ten stages returning from the game's successor, Super Smash Bros. Melee. There is up to 29 stages that are playable after turning on the game for the first time while the rest of the twelve stages can be unlocked after unlocking certain characters. For the first time in the Super Smash Bros. series, the game also offers a Stage Builder, which allows the player to make their own stage with various parts, themes, and others.
One of the stages included in the game from the Sonic franchise is Green Hill Zone, which is Sonic's home stage and it can be unlocked simply by unlocking Sonic. By default, the music is the Green Hill Zone theme song from Sonic the Hedgehog. Other music from the Sonic the Hedgehog series can be unlocked and used in this level and custom stages. The level has a number of exclusive features such as hill sides that will collapse from under players and Star Posts which can be knocked around to inflict damage on opponents. Tails, Knuckles and Silver run around in the background, making their cameo appearances.
- Green Hill Zone appears unchanged.
- Scrap Brain Zone appears unchanged.

The following trophies shown ONLY include the trophies from the Sonic series. This list does not include other game series (such as the Super Mario series) including Super Smash Bros. in the game.
- Shadow the Hedgehog is an Assist Trophy in the game. When summoned, he uses Chaos Control, which slows down everyone except the character who summoned him.
|Amy Rose||A Sonic-obsessed pink hedgehog whose full name is Amy Rose. Amy is Sonic's self-appointed girlfriend. She is almost always optimistic and cheerful, and while she motivates her friends, she also shows aggressive tendencies, like when she uses her massive Piko Piko Hammer. Speaking of which, her hammer's hiding spot remains unknown to this day.|
|Blaze||A princess from another dimension and guardian of the Sol Emeralds, also known as Blaze the Cat. Blaze is calm but often seems to be dealing with some inner turmoil. She's also extremely hard on herself, and as a result, she comes across as somewhat shy. She learns to open up after meeting Sonic and his crew and can use the Sol Emeralds to become Burning Blaze.|
|Chao||A type of creature that can absorb and learn skills and traits from other life-forms, adapting its shape as it does. This results in vast variations in appearance, behavior and personality, Chao are generally very cute, and their mannerisms are pleasant and relaxing. Chao gardens are a good place to find them, but they also inhabit areas with fresh water.|
|Cream||A young rabbit who is always accompanied by her Chao friend, Cheese. Once a member of Team Rose, she's a spirited go-getter who always gives it her all. Her polite and courteous manner is thought to be a result of her mother's strict discipline. Cream can use her large ears to fly, and her Chao Attack, where she launches Cheese like a missile, is a powerful weapon.|
|Dr. Eggman||A self-proclaimed scientific genius. Dr. Eggman sports an IQ of 300 and wants to conquer the world and build his evil empire of Eggmanland. An expert in his field, Dr. Eggman places robotics over all else in life—a reflection of his selfish personality. He doesn't know when to quit and always comes back for more no matter how many times he is defeated by Sonic.|
|Jet||A hawk who is the leader of the Babylon Rogues and also goes by the moniker "The Legendary Wind Rider." When it comes to Extreme Gear racing, there is no one better. Jet's extremely competitive and takes tremendous pride in winning, so you know things are going to be exciting when he takes on the speedy Sonic in an Extreme Gear battle.|
|Knuckles||A powerful red echidna also known by his full name, Knuckles the Echidna. Knuckles resides on Angel Island, where he guards the Master Emerald. Both friend and rival of Sonic, Knuckles is a martial-arts expert who can break through rocks with his spiked fists. In addition, he can climb walls and use the wind to glide through the air.|
|Shadow||Shadow the Hedgehog is a black hedgehog who resembles Sonic. He was created by Dr. Eggman's grandfather, Gerald Robotnik, to be the ultimate life-form. Not only does he look like Sonic, but he has equal abilities. He has great skill with the space-time warping technique called Chaos Control. To reach his goals, he'll use any means necessary.|
|Silver||A hedgehog who traveled back in time to defeat the Iblis Trigger and therefore alter the future. Silver has a positive attitude and a strong sense of justice. He has telekinetic powers that allow him to control physical objects, including abilities to freeze or shock enemies, which he uses to fight for peace and justice.|
|Sonic||The world's fastest hedgehog, who can run at supersonic speeds. Generally speaking, he loves being able to do what he wants and loathes being constrained. Holding still is something he would never consider. He's got a bit of an attitude but can't pass by someone in trouble. When he collects the seven Chaos Emeralds, he transforms into the mighty Super Sonic.|
|Super Sonic||Sonic's Final Smash. The Chaos Emeralds give energy to all living things, and Sonic's gathered all seven of them, then used their power to transform into Super Sonic. His abilities in this form far surpass his normal ones, and he's even able to fly. He uses a lot of energy in this form, so he can only remain in it for a short time.|
|Tails||A friendly fox with two tails whose true name is Miles Prower. He can fly for a limited time by spinning his tails rapidly. Originally impressed by the sight of the speedy Sonic, Tails became his sidekick, rarely leaving his side. To assist Sonic in staying one up on Dr. Eggman, Tails utilizes his knowledge of electrical engineering to create mechanical devices.|
This game contains a sticker collecting feature, providing hundreds of samples of artwork from the different games made by Nintendo. Each sticker has unique properties that can improve the stats of your character while in the Subspace Emissary. 29 of these stickers were from the Sonic the Hedgehog series (which it's shown in the list below although all other stickers are not in this list). Unlike the other games incorporated in Brawl, the Sonic stickers were separated by which game the character first appeared in rather than what game the art itself is from. Most of the artwork is from Sonic Channel.
Note: Big, Chao, Tikal and Gamma first appeared in Sonic Adventure, but are labeled as Sonic Adventure DX: Director's Cut in Brawl. Similarly, Shadow and Rouge first appeared in Sonic Adventure 2 but are labeled as Sonic Adventure 2: Battle in Brawl. These labels were most likely to note their appearances on Nintendo systems.
- Yuji Naka once considered Sonic appearing in Super Smash Bros. Melee but was unable to do so due to time constraints.  Nonetheless, EGM as part of their April Fools' Day issue, had claimed that Sonic, alongside Tails, were unlockable in Melee.
- The Chao trophy notes something that originated in Sonic X episode 22, Summer Vacation! Chao Observation Diary: Chao can not only be found in Chao Gardens, but also freshwater establishments.
- Four music tracks appearing in this game, (Scrap Brain Zone, Emerald Hill Zone, Green Hill Zone and Angel Island Zone) spell "Sega". This may or may not be a coincidence, although it could the latter.
- Though not official to the series of Sonic games, this is the first time Sonic is seen using weapons such as Beam Swords, Ray Guns, Super Scopes and other weapons in Brawl, despite the fact in Shadow's game Sonic states he is against the use of weapons by saying, "Personally, I wouldn't be caught dead using one of those things."
- Many of Sonic's attacks use the same spinning animation, and his statistics are not as refined as most other characters'.
- Early in the game's production, Nintendo asked Sega to include Sonic, but Sega refused. Some say near the end of the game's final version, Sega agreed to put Sonic in the game, which explains why the game was delayed. However, a week after the announcement of Sonic in Brawl at E for All 2007, Sonic was playable, which means Sonic was already ready for the game.
- Sonic's victory theme is taken from Sonic the Hedgehog (2006), the only victory theme ripped straight from another game.
- This is the second time that Sonic and Super Sonic can appear on-screen together, the first time was in Sonic Shuffle.
- This is the second time Sonic's shoes change color, the first time being in Sonic the Hedgehog (2006).
- All Sonic Stickers (Except Shahra, Erazor Djinn, and the Classic Sonics) are Sonic Channel Artwork.
- There's a mistake in Shadow's trophy: the description says that his first appearance was in Sonic Heroes, but that's incorrect: his first appearance was in Sonic Adventure 2.
- Jet's trophy does not reference Sonic Riders: Zero Gravity, despite appearing in the game, which was released before Brawl. However, according to the Chronicle, nothing after December 2007 was referenced in the trophies. In fact, the release date of Brawl was actually intended to be before Sonic Riders: Zero Gravity came out.
- Though Sonic the Hedgehog-related Trophies and Stickers appear in Brawl, these are not recorded in the Chronicle. This is also applied to Metal Gear-related trophies and stickers. This is due to the games not originating from Nintendo (Some other third-party games exclusively for Nintendo consoles are also recorded in the Chronicle that aren't part of Nintendo franchises, such as NBA Courtside 2002 for the Nintendo GameCube and Rareware's games like Perfect Dark and GoldenEye 007 for the Nintendo 64). Mario & Sonic at the Olympic Games may have Mario in it, but it is not recorded in the Chronicle, due to Sega handling international releases. On the Trophies, some characters' game appearances do not have the Sega Genesis or Sega Dreamcast Logos labeled; this also applied to multi-platformer games such as Sonic Heroes. This is due to Brawl being a Nintendo game, thus even though they appeared in those games, the game only labels the Nintendo appearances (if any).
- Sonic's side taunt, "You're too slow!", has become an Internet meme some time after the game's release.
- Solid Snake's codec call when battling Sonic is an inside joke for the Japanese. Snake comments on how there's something he doesn't like about Sonic, giving no specific reason. This is because Snake's Japanese voice is the son of the Japanese voice of Sonic's arch-enemy, Dr. Eggman.
- However, Americans can find this joke funny, but in a different way: hedgehogs are known to actually eat snakes.
- Sonic's inclusion in Brawl has made him the fastest character in the game, taking the title from Captain Falcon. His pace is so fast that when he's wearing the Bunny Hood item, he can outrace the F-Zero machines in the stage Big Blue (Although it's possible to run for a few seconds without it), and the waterfall in the Pikmin stage, Distant Planet. In addition to the Bunny Hood item, if the player sets the game to a Mega Brawl and Sonic gets Superspicy Curry and a Super Mushroom, he can outrun the avalanche in the Ice Climber's stage, Summit.
- Sonic is capable of swimming in Brawl, like the game's other characters, despite not being able to swim in his own games. However, he is one of the slowest swimmers in the game. In addition, when he is swimming, he flops in the water.
- Sonic's artwork for Super Smash Bros. Brawl is reused three times in the Sonic the Hedgehog series:
- In Sonic and the Black Knight, Sonic uses an oil canvas version on the "character selection" screen.
- In Mario & Sonic at the Olympic Winter Games, a Sonic snowman can be purchased at the secret shop. This Sonic Snowman is in his Super Smash Bros. Brawl pose.
- In Sonic Generations, when clearing a level with a B rank as Classic Sonic, he will pose like his artwork.
- Sonic is one of the only characters in the Subspace Emissary to not be seen as a trophy alongside Zero Suit Samus, Sheik and Squirtle, possibly because of his late appearance. However, Sonic is the only of these four to never be defeated. Coincidentally, all these characters are blue and have names starting with "S".
- Super Smash Bros. Brawl marks the first time since Sonic & Knuckles where, under certain circumstances, Sonic can transform into Super Sonic at any time.
- In early versions of the game (such as games that were pre-ordered), Sonic's trophy says "When he collects the seven Chaos Emeralds, he transforms into the mighty god Super Sonic" instead of "the mighty gold Super Sonic" This was fixed later on, but the Prima guide for the game still says "god".
- Interestingly, Sonic, Kirby, Captain Falcon and Pikachu all had television shows dubbed by 4Kids: Sonic X, Kirby: Right Back at Ya!, F-Zero: GP Legends and Pokémon.
- In the game, Sonic transforms into Super Sonic before the Chaos Emeralds enter his body.
- The Isle of the Ancients bears an uncanny resemblance to Angel Island.
- This is the first game since Sonic the Hedgehog CD to feature the Super Peel Out, as well as the first 3D game to feature said move.
- Sonic Lost World would later bring this maneuver back.
- This game emphasizes the offensive use of Sonic's quills, using them as spikes in his up throw and in his spinball form in most of his attacks.
- The Shadow the Hedgehog trophy has nearly the same pose that he used in his artwork for the game Sonic the Hedgehog (2006).
- This is one of the few times Sonic has a different color (besides turning into Super Sonic).
- There are several games listed on character Trophy/Stickers that were never on a Nintendo console.
- Sonic's appearance at the end of the Subspace Emissary is similar to Super Sonic's appearance in some of the Sonic games, as both appear near the end to take on the final boss.
- Sonic and Lucario are the only characters who remain their normal color when put on Team Blue.
- Though characters like Mario, Sonic, Lucario, and Samus were the most popular in the game, Kirby, Meta Knight, and King Dedede from the Kirby series are the most important characters in the story mode, though few notice this.
- On Sonic's yellow palette swap, his gold cuffs look very similar to Silver's gloves without the blue design on them.
Behind the scenes
Allusions to the Sonic series
Similar to several cross-series/cross-game fighting games, there were several allusions to the Sonic series.
- The final chapter of the Subspace Emissary bore some resemblance to the last story of Sonic the Hedgehog (2006). In both instances, the main antagonist, who has god-like abilities, managed to nearly wreck the entire fabric of existence from behind the scenes (in the Subspace Emissary, Tabuu managed to render virtually the entire Trophy World into Subspace. In Sonic the Hedgehog (2006), Mephiles the Dark managed to wreck the time/space plane of existence by merging with Iblis to reform Solaris). Both villains also managed to wipe out at least one important character, only for unanticipated circumstances to bring them back (In the Subspace Emissary, Tabuu manages to wipe out all of the heroes and revert them into trophies, the only thing reversing it being the badges that King Dedede gave some of the trophies [and in the case of Kirby, that Kirby ate after discovering it]. In Sonic the Hedgehog (2006), Sonic ends up killed by Mephiles, and the other characters were also implied to have been nearly killed by Solaris' damage to the time/space plane, only managing to undo Sonic's death via the Chaos Emeralds). Both instances also have them revisit various copies of their world in order to track down the means to defeating the villain/the villain itself (In the Subspace Emissary, after discovering the door to Tabuu's realm, they enter an area that featured several copies of the worlds and even resurrected bosses later on. In Sonic the Hedgehog (2006), the heroes have to go to various copies of all but two of the worlds in the game in order to retrieve the Chaos Emeralds and thus revive him for him, Shadow, and Silver to fight off Solaris and defeat him once and for all.) Also, several variations of the Super Smash Bros. Brawl main theme are in the soundtrack just like how "His World" has several variations in Sonic the Hedgehog (2006).
- Sonic's fighting style was mostly modeled after his fighting style in Sonic the Fighters.
- Erazor Djinn's sticker increases the characters' fire-based attacks, referring to the events of Sonic and the Secret Rings, where Erazor fires a burning arrow at Shahra and Sonic intercepts it, forcing him to collect the titular Seven World Rings in order to put it out and be spared of death.
