- You may be looking for the Chaotix of Mobius Prime, the group from Light Mobius, or the incarnation from the Sonic X Zone.
The Chaotix are a trio of Mobians consisting of Vector the Crocodile, Espio the Chameleon, and Charmy Bee. Hailing from the Zone known as Another Time, Another Place, they are friends and allies of Sonic the Hedgehog. All three were in attendance at a surprise birthday held for Sonic along with Knuckles the Echidna, Tails, Amy Rose, Blaze the Cat, Cream the Rabbit, and Rouge the Bat. With the exception of Sonic, all the attendees were sent through a series of portals opened by the malevolent Time Eater. (StH: #230)
Some time later, the Chaotix took part in the Olympic Games as a rowing team, only to be captured by Dr. Eggman. The scientist succeeded in capturing all the other competitors and observers-including Shadow the Hedgehog, Silver the Hedgehog, and Marine the Raccoon-except for Sonic. Fortunately, the blue hero was able to tap into the spirit of the Olympics and free his friends. (StH: #242)
- Though it has yet to be seen, these versions of the Chaotix presumably met Sonic and the others through events similar to the games Knuckles Chaotix and Sonic Heroes.
