Espio the Chameleon is an anthropomorphic chameleon who is an expert ninja. He is also 16 years old. He is described as the "guardian of honor" of the Chaotix, also being the calmest. He has a "militaristic discipline" while also being quiet and laid back. Confident in his skills, opinionated and self-obsessed, he revels in training and self discipline. He is not concerned by danger, and often yearns to face it in order to use his ninja skills. With his extensive training in ninjutsu and an ability to turn himself invisible, he is able to move around unnoticed. However, a blunder like a sneeze could cause him to inadvertently become visible. Espio also made an appearance in Mario and Sonic at the Olympic Games as a referee. GameZone staff writer Louis Bedigian claimed that "Espio must think he's part hedgehog because he can speed boost and become invisible".
Lindsey Thorndyke is Christopher Thorndyke's mother.
Age: 42 Years old Weight: 151lb Height: 5'9" __________________________________ In Episode 14, he calls the military to bring Sonic to the White House for a party (who refuses because of a planned outing with Chris' friend, Helen), and goes as far as to get the reporters purposely drunk (in the dub, it's toned down) so they'll stay. In Episode 21, he initially decides to call the military in (since Sonic refuses to race against Chris's uncle, Sam Speed), but decides against it and secretly calls Eggman and asks for his help. At the end, Jerome is exposed for making the deal, and is fired. Occasionally, one will see him as a homeless man in later episodes.
