Sonic Rivals is a 2006 racing, platformer video game developed by Backbone Entertainment under supervision of Sega Studio USA exclusively for the PlayStation Portable. The game was released in November 2006 to celebrate the 15th anniversary of the franchise. A sequel titled Sonic Rivals 2 was released in the following year.


For the scripts of each individual storyline, see Category:Sonic Rivals scripts.


Sonic the Hedgehog and his best buddy Miles "Tails" Prower investigate a mysterious land mass named "Onyx Island" which has suddenly appeared as if out of nowhere. The heroic duo spot Dr. Eggman who is already waiting for them and confronts him, suspecting that Eggman is plotting an evil scheme. Eggman reveals a card containing Amy Rose he took with a special camera which shocked Sonic and Tails. Sonic did not believe in this but Tails examined that it was scientifically possible for Amy to end up in her current state.

While Tails is conserving to Sonic about this, there is a sudden flash of light and Tails is gone, appearing as a card in Eggman's hand. Sonic panicked in disbelief upon this sight and at that moment, Knuckles the Echidna appeared and yelled at Eggman for causing the Master Emerald to disappear. Eggman responded by showing him a card of the Master Emerald and announces to achieve world domination by snapping everything with his camera so that the world is "nothing more than his lovely card collection" and issues Sonic and Knuckles a challenge to stop him and reclaim their desired cards before making his escape.[2]

Sonic's Story

After accepting Eggman's challenge, Sonic raced against Knuckles throughout Forest Falls Zone to reach Eggman first. After reaching Eggman, Sonic demanded Tails and Amy's cards from the doctor who responded that if Sonic could defeat his Egg Turtle, he may allow the hedgehog a card of his choosing. Knuckles intervened that was not part of Eggman's deal, but Sonic was confident and accepted the challenge.

After defeating the Egg Turtle, Eggman turned to leave afterwards with Sonic at his tail but Silver appeared and told Sonic not to interfere as he had business with Eggman as well. Sonic did not appreciate the hedgehog's attitude and asked for his name. After having introduced himself, Silver disclosed was that he simply wanted to get to Eggman before Sonic. Being not the one to turn down a challenge, Sonic happily accepted to race against his new rival. After a race against Silver through Colosseum Highway Zone, Sonic reached Eggman and once again demanded the cards from him but Silver's not through with Sonic and they both confronted Eggman's Egg Falcon against each other.

As the fight continued, Silver deemed it too dangerous to get close to Sonic and teleported him to Sky Park Zone. While there, Sonic encountered Shadow and thought he was looking for Eggman as well, leading to a race between the arch-rivals. After that, Sonic came out on top, feeling proud of himself for doing so. Eggman appeared and complimented on his victory and issued Metal Sonic to race against his organic doppelgänger, seeing whether Sonic is really the fastest thing in the world. Sonic outraced Metal Sonic but Eggman, before making his getaway, mentioned something about the strongest and fastest to which Sonic becomes suspicious about. He then met Silver again and claims he figured out the doctor's motives, causing Silver to race against him once again.

After a race through Crystal Mountain Zone, Sonic caught up to Eggman, proving to him that he is the fastest and the strongest and demands Tails' card. Eggman muttered to himself that he had enough data for an unknown purpose and intends to defeat Sonic so no one could interfere with him in the past or the future with the Egg Lynx. When that failed, Sonic finally retrieved Tails' card, restoring him to normal. Knuckles appeared and was shocked to see Tails restored. Sonic mocked that Knuckles will have to be quicker to stay on Eggman's heels, with the latter retaliating by challenging Sonic to a race once again.

Racing through Death Yard Zone, Sonic beat Knuckles and caught up with Eggman. The doctor sends an upgraded Metal Sonic to race against Sonic but the robot doppelganger lost again. Frustrated with this result, Dr. Eggman decided to team up with Metal Sonic against Sonic with the Egg Kong. Sonic still defeated the Egg Kong which resulted in Eggman losing it and departs for outer space to use his special camera to turn the entire planet into a card. Knuckles arrived, noting he was too late. Tails arrived with a new Tornado plane so the trio could catch up to Eggman.

Riding to Eggman's Meteor Base Zone in outer-space, Sonic set his differences with his rivals aside as they aided him to navigate through the base to find Eggman. Soon, Sonic and Tails spotted Eggman trying to escape into a giant rocket with the special camera attached. Dr. Eggman claimed that he had enough energy to take a picture of the planet after he places one final card into his energy transfer device. Sonic remembered it to be Amy's card which he has forgotten about. Not intending to let Eggman succeed, Sonic confronted the doctor on his rocket and defeated Eggman before restoring Amy. Amy was happy of Sonic's heroism and suggested they could live together forever but Sonic came up with an excuse to rescue other victims trapped in Eggman's cards.

Knuckles' Story

Knuckles arrived at Onyx Island in order to discover the disappearance of the Master Emerald, noting that the island had a similar presence. He spots Dr. Eggman and suspected at him for the disappearance of the Master Emerald. The doctor admits this and issues him a challenge if he wished to reclaim it back. Knuckles had to race against Sonic who also needed to reach Eggman through Forest Falls Zone. After reaching Eggman, Knuckles asked Eggman to maintain his promise to give him the Master Emerald card but the doctor would only consider giving it if he beats the Egg Turtle, much to Knuckles' disgrace who resolves to take it back with force.

After defeating the Egg Turtle, Eggman escaped and then Shadow appeared who mocked at Knuckles for allowing the doctor to escape. Not appreciating Shadow's insult, Knuckles is nearly about to retaliate until Shadow wanted business with the doctor, tempting Knuckles to race him throughout Colosseum Highway Zone. The duo encountered Eggman and demanded their business with him but Eggman uncooperatively refuses to do so and attacked them with his Egg Falcon.

After it is destroyed, Eggman seemingly wanted to give the Master Emerald card to Knuckles only to trick him and make his escape again. Knuckles is then transported to Sky Park Zone where he encountered Silver who mumbled to him about what Eggman is carrying. Knuckles explains the camera's function which triggered Silver to ask how the doctor obtained it in a rude manner before leaving with Knuckles on his trail. Knuckles caught up to Eggman and wanted to know how he managed to make the Master Emerald disappear from Angel Island in the first place before the doctor gave a response that the land mass he is at currently is actually Angel Island, leaving Knuckles confused. Eggman then issued Metal Sonic to race against Knuckles.

Shadow's Story

Shadow is summoned to a strange island by Dr. Eggman via a cryptic transmission asking for his aid, Shadow is able to successfully locate Eggman, but once he mentions the cryptic message to the doctor, Eggman denies it. The mystery continues to unfold itself as Rouge warns him of an impending danger and upon stumbling across a secret about Eggman, her transmission is cut short. Shadow continues his quest to uncover the truth about Dr. Eggman.

Upon encountering him several times, Eggman admits that he is Doctor Eggman Nega who plans to take a picture of the entire world (and trapping it in a card) within his camera. The real Doctor Eggman is eventually rescued who escorts him to Nega's space station to stop Nega's ultimatum. Along the way, he is assisted by Silver and Sonic. After defeating Eggman Nega, Rouge is finally rescued.

Silver's Story

Hailing from the future, Silver was responding to a distress signal, of an unknown source. He later discovered that Dr. Eggman Nega is linked to this distress signal and was using a strange camera to turn people and/or objects into cards. Silver states that he will bring Eggman Nega back to the future where he belongs.

Unlockable Costumes

Collecting all of a character's cards will unlock outfits related to that character. For example, collecting all of Amy's cards unlocks a pink track suit that can be equipped into one of the rivals (although this appears to be missing in the final version of the game for some reason).[8]

  • Sonic: Leather, Ice, Black Tie
  • Knuckles: Leather, Armor, Eggman
  • Shadow: Leather, Flame, 80's
  • Silver: Leather, Lightning, Christmas

Chris Renzanson is the main composer of Sonic Rivals.[23][24][25] A track entitled "Quick Trip To Paradise" was composed by Lee Brotherton and used as the music for the Forest Falls Zone and the title screen of the game.[26][27][28]


Sonic Rivals features an extensive collectible card system that spans a total of 150 cards, featuring cameo appearances of robots, major characters, minor characters, boxarts, and items from past Sonic games such as Sonic Heroes, Sonic Adventure, Shadow the Hedgehog, and even dating back to Sonic the Hedgehog. The cards themselves are used to unlock secret costumes for the characters among other things.


The game received mixed to positive reviews upon release. IGN rated the game a 7.4 out of 10, highlighting its replay value, its graphics, as well as its entertaining stages. GameSpot, which rated the game 6.9/10 said there was a good sense of speed and colorful graphics but that the level design was frustrating and tedious to get through.
