Who are Team Chaotix

Team Chaotix is a detective agency first and foremost.
Team Chaotix, according to Sonic Heroes, consists of Vector the Crocile (Age 20), generally seen as the leader and also very powerful, Espio the Chameleon (Age 16), who is not only a spy but a ninja as well, and Charmy Bee (Age 6), often seen as the "mascot" of Team Chaotix, but is also important in terms of flight.
However, according to the Sonic the Hedgehog comic (Archie Comics), other members include Saffron (Charmy's supposed girlfriend), Julie-Su (Knuckles the Echidna's supposed girlfriend), Ray the Flying Squirrel, and for some time Knuckles the Echidna himself.
But generally, when people talk about the Chaotix, they're usually referring to Vector, Espio, and Charmy.

Vector the crocodile is the power type and Captain of the Team.
Espio the Chameleon is the speed type and Vice-Captain of the Team.
Charmy bee is the fly type and "Worker" of the Team
And thats Team Chaotix!
