Chaotix

The Chaotix are Angel Island's group of freedom fighters. They were originally created for the video game Knuckles Chaotix for the 32X, and later became a semi-regular part of both comic and video game continuity. The Chaotix includes Bomb, Charmy, Espio, Heavy, Knuckles, Ray, Mighty, and Vector. Some of these characters made appearances in earlier video games (Ray and Mighty in SegaSonic the Hedgehog and Knuckles, of course, in Sonic the Hedgehog 3), but they were later made into a team.

Sega continuities
The first appearance of the Chaotix was an immense team of eight members.

A later 'abbreviated' version of the original Chaotix team, composed of just Charmy, Espio, and Vector, would appear as a team in Sonic Heroes, this same team would also appear in Shadow the Hedgehog, all of them in a cutscene, and each available as a comrade at some point.

Espio and Vector appear in Sonic Rivals 2, Vector orders Espio to investigate the chao.

Archie continuity
The first appearance of the Chaotix was in a Sonic Super Special. For a time, they appeared (along with Knuckles) in the more 'serious' Archie comic, Knuckles the Echidna.

Sonic X continuity
The abbreviated version seen in Sonic Heroes appeared for one episode in season 2, and played a major part in season 3.
