Espio the Chameleon

Espio the Chameleon is a character from the Sonic the Hedgehog series. A chameleon, he is a member of the private investigative agency Chaotix. In Worlds Collide, Espio, alongside team members Vector the Crocodile and Charmy Bee, were tasked by Sonic the Hedgehog to investigate the disappearances of Miles "Tails" Prower, Knuckles the Echidna, Amy Rose, and Shadow the Hedgehog. However, as they were investigating, they ended up captured by Copy Robot via a teleportation beam. Espio was then transformed into the Roboticized Master Espio Man by Dr. Wily and Dr. Eggman. His special ability was Chroma Camo. Shortly after the Genesis Unit and Copy Robot were defeated by Sonic, Proto Man, Mega Man, Rush, and Tails, Espio Man, alongside Vector Man and Charmy Man, were dispatched by the two doctors to fight them. After Charmy Man and Vector Man had been defeated, Espio Man camouflaged himself in an attempt to sneak attack Mega Man from behind, although Sonic managed to subdue him before he could act on the opportunity, after Rush detected the Roboticized Master with his smell. Upon being restored to his true form, Espio, out of a life debt, supplied Mega Man with the orb containing Espio Man's Chroma Camo ability.

During the Robot Master battle, Espio entered into a private (and likely obligatory) ninja duel with the original Shadow Man.

Trivia

 * During Sonic's fight with the Roboticized Team Chaotix, Sonic suggested that Espio Man be given the name "Sting -" before being cut off, referring to the Maverick Hunter-turned-Maverick boss in Mega Man X and Mega Man: Maverick Hunter X, Sting Chameleon.
