 Espio the Chameleon
Espio is a purple chameleon, who is a ninja. He is the fastest member of the Chaotix. He uses his kanais and shurikens as his weapons and is notably the only Sonic character to actually use real weapons. Espio made his debut in Knuckles Chaotix. He later appeared in Sonic Heroes as a part of Team Chaotix. He also appears in a few other games, including Mario & Sonic at the Olympic Games as a referee.
 Charmy Bee
Charmy is the youngest member of the Chaotix, at the age of 6. He doesn't take his job as seriously as the other Chaotix. He uses his stinger as a weapon. Charmy made his debut in Knuckles Chaotix. He later appeared in Sonic Heroes as a part of Team Chaotix. He also appears in a few other games, including Mario & Sonic at the Olympic Games as a referee.
 Mighty the Armadillo
Mighty is an armadillo with a red shell. Unlike the other Chaotix, Mighty made his debut in SegaSonic the Hedgehog and did not appear in Sonic Heroes. He appeared in Knuckles Chaotix with the other Chaotix, but he never appeared in another game after that.
 In Other Media
The Chaotix also appear in the Sonic X anime as their current 3-man team shown in the most recent games.
They also appear in both the Archie Comics continuity and Sonic the Comic. In both these versions Mighty was included and the groups were expanded slightly. For the Archie comics version Ray the Flying Squirrel, Saffron Bee and Julie-Su were also included in the group. In the Sonic the Comic version Nack the Weasel was a member until he betrayed the group for money.
