Charmy is an extremely hyperactive anthropomorphic honeybee with a big heart. He is youngest member and co-founder of the Chaotix Detective Agency. Charmy first appeared in the Sonic the Hedgehog manga, but was later used for the games, in which he first debuted in Knuckles' Chaotix.

While Charmy is always hyperactive, bee-brained, loud, immature and often gets on his teammates' nerves, his tracking skills are nonetheless an invaluable assist to the Chaotix Detective Agency and a crucial part of their team. As such, both Vector and Espio treat Charmy as their equal.
