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.
