Espio the Chameleon (エスピオ・ザ・カメレオン Esupio za Kamereon?) is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic chameleon, where mainly serves as an intelligent ninja warrior and a member of the Chaotix Detective Agency. There, he works together with Vector the Crocodile and Charmy Bee to solve whatever cases they are given, where he puts his skills to good use. While initially a hothead when introduced, Espio has since become a calm, soft-spoken, serious, and disciplined person whose wariness and soulful character makes him a vital member of his team, and balances out the foolishness of his friends.


Knuckles' Chaotix


Espio in Knuckles Chaotix.

Espio first appeared in Knuckles' Chaotix for the Sega 32X. In the English manual, he is described as the hot-headed friend of Knuckles the Echidna (the surprisingly sophisticated Charmy Bee is said to keep him from losing his temper), and is visiting "Carnival Island" when Dr. Robotnik attacks it. The Japanese manual states that Espio, a detective, went to investigate the mysterious island that emerged from the sea.

In both cases, he is attacked by Dr. Robotnik and Metal Sonic who try to capture him. Knuckles saves him from the two, and Espio automatically becomes his partner character for the training stage. After this, Espio can be chosen in the Combi Catcher prior to stages. Espio can walk on walls and ceilings, and uses his own Whirl Attack instead of the common Spin Attack.

Sonic the Fighters

Espio appears as one of eight playable fighters in the arcade game Sonic the Fighters (Sonic Championship in Japan). In the story, Espio is one of the eight characters who try to collect the eight Chaos Emeralds in order to travel into space and destroy Eggman's Death Egg II. Espio is the fourth character to fight in story mode, and his stage is Mushroom Hill, a part of Angel Island that appeared in Sonic & Knuckles.

In the game, Espio is a medium-strong fighter, and his special abilities include using his Whirl Attack and attacking with his long tongue.

Sonic Heroes

Espio in Sonic Heroes.

In Sonic Heroes, Espio, Vector and Charmy have formed a detective agency (previously, only Espio was described as "a detective"). They are contacted by an anonymous client via a walkie-talkie that was delivered to them. Espio does not entirely trust the voice, but Vector and Charmy had accepted the assignment after they get promised a reward of money, with Espio tagging along anyway after Vector reminds him of their policy to never turn down work that pays. In the game, Espio is the speed member of Team Chaotix, meaning he can run quicker than the others, and creates small whirlwinds for various purposes. Unlike the speed members of the other three teams, Espio can turn invisible, throw large shurikens (ninja stars) and stick to walls indefinitely. He and the other two also have a run-in with Team Dark and Team Rose, the former due to Rouge believing them to be after Eggman's treasure and their likewise believing that Team Dark are affiliated with Eggman, and the latter due to a misunderstanding that causes Cream to think they had abducted Chocola the Chao after Espio tells her to give Cheese over to him.

At the end of their story, the client is rescued from Eggman's base, and turns out to be Dr. Eggman himself, to Espio's surprise. Eggman reveals that he had been betrayed and captured by the evil Neo Metal Sonic, who has gathered everyone's data and then transforms into Metal Madness shortly after. Team Chaotix had the Chaos Emeralds throughout the game, with Espio holding the red one. Team Chaotix then stalls Metal Madness in order to buy time for Sonic to turn into his Super State, and for Tails and Knuckles to obtain Super Shields. At the end of the game, Eggman tries to sneak away, but the Chaotix chase after him to collect their promised reward.

Shadow the Hedgehog

In Shadow the Hedgehog, the Chaotix work on a new mission. He appears in the cutscene prior to the Mad Matrix stage, in which he and Shadow the Hedgehog hack into the cyberspace of Eggman's computer system. The player can then choose whether or not to help Espio retrieve encrypted data from the computer, with Espio being a "partner" character in the stage. In the GameCube and PlayStation 2 versions of the game, the second controller can be used to control Espio, who attacks with punch combos and homing attacks.

In the game's ending, the Chaotix are all on the Space Colony ARK. Vector and Charmy are putting pressure on Espio to hurry to recover data from the computers. Espio replies "Easier said than done, who signed me up for this anyway?" At this, Charmy gets a little impatient and he kicks the computers which activates an old video created by Gerald Robotnik for Shadow to see. When Shadow sees it, he gains new strength and defeats the main villain, Black Doom, as Super Shadow.

Sonic Generations

In the console/PC version of Sonic Generations, Espio attended and helped prepare Sonic's surprise birthday party. As the party began, however, the Time Eater suddenly appeared and Espio was sucked into one of the Time Eater's Time Holes and ended up in the White Space, where he was turned into a statue due to the Time Eater's effects.

Sonic Generations Espio7

Eventually, Espio was returned to normal by Sonic and his younger self. When the Sonics confronted the Time Eater in the Center of Time, which the monster was revealed to be controlled by Dr. Eggman and his younger self, Espio arrived at the place with the others and cheered on both Sonics, allowing them both to transform into Super Sonic. When the Sonics defeated the Time Eater, Espio and the others were sent back to the time where Sonic's party who taking place. Resuming with the celebration, Espio later waved goodbye to the younger Sonic and Tails when they returned to their own time.

Mario and Sonic series

Mario and Sonic at the Olympic Winter Games

Espio appears once again as a referee in Mario and Sonic at the Olympic Winter Games. He is seen either standing next to the starting gate or firing a starting pistol. In the DS version, Espio will tell you how many white stones are left on Winter Island (Frostown, Polastraits, Icepeak). You can also unlock an Espio outfit that your Mii can wear.

Mario and Sonic at the Olympic Games

Espio appears as one of the referees in Mario and Sonic at the Olympic Games. It may have been that he was once supposed to be playable, but no evidence to that has been provided to date. He is playable to some extent through hacks of the game.

Mario & Sonic at the London 2012 Olympic Games

Espio also appears again as a referee in Mario & Sonic at the London 2012 Olympic Games. His Mii costume can also be unlocked in the Blank Exchange, or given to you as a present.

Sonic Runners

In Sonic Runners, Espio is a playable Speed Type character in the game. In gameplay, he can use a triple jump and he boosts the number of collected Rings by 75%.

During the "Birthday on Windy Hill" event, Espio was going to Sonic's birthday party with the other Chaotix when they got kidnapped by Dr. Eggman. They soon escaped their holding place, but not before learning that Eggman plotted something in a nearby base. When they found Team Sonic, Espio, on Vector's order, used his camouflage skills to give Sonic a birthday surprise before telling them about Eggman. Though the info turned out to be a trap, Espio rejoined Sonic at the party after Eggman was beaten, where he expressed gratitude at Sonic's efforts.


Espio profile SG

Espio's profile in Sonic Generations.

Espio is very serious, quiet, level-headed, wise and disciplined, but also opinionated and somewhat arrogant at times. Despite this fact, he is usually eager to find danger to flex and polish his ninja skills. He is seen as a ninja-based character; his battle poses and shuriken stars support that portrayal. In Sonic Heroes, he plays the shamisen in the Chaotix's Team Blast, "Chaotix Recital". According to the Japanese game manual of Knuckles Chaotix, Espio especially dislikes Dr. Eggman, although it's not stated precisely why, but during a cutscene in Sonic Heroes, the usual civil and soft-spoken chameleon even threatened the doctor's life. He is also able to see through Eggman's tricks very easily in Shadow the Hedgehog, and tells Shadow to destroy the villain.

Powers and abilities

In Knuckles' Chaotix, Espio had the ability to stick and walk along walls as if he was walking on the floor, and possessed his own unique Spin Jump, Spin Attack, and Spin Dash abilities known as the "whirling attack" (known as "Espio spin" in Sonic the Fighters) in which he would spin horizontally as opposed to vertically.

In Sonic the Fighters, Espio displayed the ability to stretch his tongue and launch it at opponents.

In Sonic Heroes, Espio was reintroduced as a ninja and boasted new skills, such as whirlwind attack known as Leaf Swirl and the ability to throw large shuriken. Espio also displayed the unique ability to stick to walls whilst performing the Triangle Jump. It was also revealed that Espio could play the shamisen, through Team Chaotix's Team Blast: Chaotix Recital. The opening of Team Chaotix's story also shows that Espio is skilled in using Kunai as throwing weapons; as he was able to use one to nail an airborne package to a wall. As a Speed Type character, Espio is quite fast, and can perform the Homing Attack, Rocket Accel, and the aforementioned Triangle Jump.

As a Chameleon, Espio's most prominent ability is to render his skin to match the environment, which makes him completely invisible and undetected by enemies and lasers alike. Espio can remain invisible for as long as he pleases. although he will become visible again as well if he loses focus, such as when sneezing,[2] being blinded or taking damage.

Espio could also render himself invisible as part of his Signature Move, Chroma Camo, in Sonic Rivals 2. Whilst using Chroma Camo, Espio is undetectable and cannot be hit by powerups as well as gaining a small speed boost. The ability lasts until all energy in the Signature Meter runs out. If the player presses the square button, they can slightly extend the move.

As a ninja, Espio has displayed some skill at Ninjutsu. This is largely helped by his ability to turn himself invisible, but is also shown through his skill in martial arts and his proficiency with weaponry and equipment, such as Shuriken and Kunai.

Espio has a great degree of super speed As seen in Sonic Heroes, his speed surpasses Amy's speed and he is fast enough to outrun obstacles and match the fastest characters in the series and is said that his speed can fool up enemies[3], though he is still not as fast as Sonic and Shadow.


Shadow the Hedgehog

The relationship between Espio and Shadow the Hedgehog has changed very much since their first meeting. In Sonic Heroes, they fought against each other without a question due to their assumption that the other was the enemy. However, they put their differences aside, and helped each other stop Metal Sonic and his plan to rule over world.

In Shadow the Hedgehog, their relationship is more friendly. Espio gladly thanked Shadow for opening the portal to Eggman's computer and after Eggman claimed that he created Shadow, Espio told him to not believe Eggman and aided him in his battle against the doctor. Overall, Espio has put more faith in Shadow since their meeting and the two appear allies in most regard.



Appearances in other media

Sonic the Comic

In Sonic the Comic, Espio is a member of the Chaotix Crew and a native of the Special Zone. He is a friendly (or sometimes not so friendly) rival to Mighty and has an extremely short temper. The two of them will end up clashing and arguing who's the best on almost any subject, to the extent of demanding a defeated enemy says which of them had punched him the hardest.[4] This incarnation of the character differs significantly from the Espio portrayed in the games and Sonic X.

Espio has the ability to turn invisible, although he rarely uses this talent.[5][6]

Espio's profile in Knuckles Knock-Out Special says that he was once a prisoner in Robotnik's Combi Machine, and that he has a personal grudge against Robotnik for this. However, this is never mentioned in any strip in the series, and may not be canon.

Archie Comics

In the Sonic the Hedgehog comics, Espio is a bonafide hothead, which causes his friend Charmy to constantly remind him of his manners. This incarnation of the character differs significantly from the Espio portrayed in the games and Sonic X.

Sonic X

Espio appeared with Team Chaotix in the anime Sonic X. Along with Vector and Charmy, Espio played a minor role in season 2, only appearing in Episode 39 to help find Cream when Chaotix was hired by Vanilla, Cream's mother (though in the end, it is Sonic who unites the two). In this episode Espio along with Vector and Charmy broke the proverbial fourth-wall by introducing themselves to the audience (Charmy mostly since he begged for more time to introduce himself). They play a larger role in Season 3, first appearing to bring Chris supplies from his parents. The second time Espio appears, he reluctantly helps Vector and Charmy help Tails get Cosmo, a girl he likes, to like him back, and after that appears with the others to help fight the Metarex. Espio states in his first appearance that he is the brains behind the Chaotix (to which Charmy claims that he's "Super Full of Himself"), when in the Sonic Heroes instruction manual, Vector is stated to be the brains. In the anime he is sometimes seen as a comic relief character as he has been hit (unintentionally) by Amy's hammer, woken up by Vector when he had pepper poured on him and was discovered in a humiliating way shortly before being clobbered.

Theme songs

"Team Chaotix" (although this theme is shared with Vector the Crocodile and Charmy Bee, Espio is mentioned in the two lines: "And the ninja stars fly, too!" and "Espio is clearly ready to go".)

  • According to Takashi Iizuka, Espio and the Team Chaotix in Sonic Heroes were recreated as new characters from the same characters in Knuckles' Chaotix when Sonic Heroes was designed, ignoring certain traits that had been established in Knuckles' Chaotix that would have contradicted their intent in the game.[7]
  • Espio's name is thought to either have been derived from the word "espionage", meaning spying; it also may be a reference to the Spanish and Portuguese word "espío" (literally meaning "I spy").
  • Espio is the only member of Team Chaotix to appear in a game (Sonic the Fighters) released between Knuckles' Chaotix and Sonic Heroes.
  • Espio is the second-most used member of Team Chaotix. He has less game appearances than Vector but more than Charmy.
  • In Sonic Heroes, Espio is the only speed formation character whose shoes are not partly red. He is also the only speed formation character who is not a hedgehog.
  • Throughout the series, Espio's color gradually lightens from a dark purple to a light pinkish purple.
  • In the Shadow the Hedgehog boss Egg Breaker, when Shadow destroys any of Eggman's robots, Espio says, "Stop that! We can't let Eggman know we're here!" which is repeated from the previous level. However, Eggman already knows that Espio and Shadow were in his base as he is fighting them.
  • In Shadow the Hedgehog, Espio is one of the five characters to swear (the others being Shadow, Sonic, Knuckles, and the GUN Commander).
  • Espio is the only playable character in Sonic Rivals 2 who did not appear in the story mode of Sonic Rivals.
  • In Sonic Generations, Espio is the one of the two characters who did not notice Sonic was different after being rescued. The other was Vector.

  • In a cutscene from Shadow the Hedgehog, Eggman calls Shadow and Espio "Rodents" although Espio is a reptile.
