Espio the Chameleon (エスピオ・ザ・カメレオン Esupio za Kamereon) is a fictional character from the Sonic the Hedgehog series. He is an anthropomorphic chameleon, who mainly serves as an intelligent ninja warrior and a member of the Chaotix Detective Agency alongside Vector the Crocodile and Charmy Bee. Together, the trio solves whatever cases they are given, where Espio is able to put his skills to good use. He possesses as well the ability to blend in with his environment. Espio is a calm and quiet chameleon, but also overly cautious and disciplined. However, his wariness and soulful character makes him a vital member of Team Chaotix, where his presence plays an important role as a restraint among his coworkers, who tend to be optimistic and energetic. Espio likewise thrives on the dangers of his missions, and although he is quite confident in his ninjutsu, he feels it is aesthetically pleasing to stay in the shadows as a ninja should.
