Physical description








Alignment and character traits


Mr. Stewart (スチュワート Suchuwāto?) is a minor character in the anime series Sonic X and its comic series published by Archie Comics. He is a government agent working undercover as a school teacher assigned to watch Sonic the Hedgehog and his friends by the President under the code name "Teacher" (Japanese version)/ "Chalkboard Charlie" (English version).


He taught Christopher Thorndyke and his classmates, including Danny, Frances, and Helen. Mister Stewart always looked out for the kids in his class. The kids weren't so sure about Mister Stewart at first until Episode 32, when they started to display a likeness to him. But to his irritation, he was given a new alias and assignment- to pose as a News Director and investigate Project Shadow -in the episode immediately following.

In the Chaos Emerald Tournament, Mister Stewart was no match for Sam Speed, but Sam started before they rang the starting bell, causing Stewart to win the battle by default. In the finals, Scarlet Garcia recognized him as the News Director she helped during the Sonic Adventure 2 adaption, so he forfeited his match with Lucky saying "My cover has been BLOWN!"


He wears a blue coat, glasses, a turquoise vest, a white sweater, and dark grey pants. He has blond hair and owns a green-blue spy car, which can transform into vehicle for water travel and has numerous other gadgets. He also is good at basketball; he says he was an alternate on the practice squad back when he was in College.


Stewart is not without sentimental emotions, as he does care for Chris too. In Episode 4, Chris had fallen and Mr. Stewart turned his car into a mattress and was about to save him, until Sonic came into the rescue to save him. Stewart also comes over to Chris's house for dinner, though that was probably more for the sake of gathering information for the government concerning whether or not Sonic and his friends really were living at Thorndyke Manor. It is interesting to note that there is no real reason to believe that Stewart is even his real name, as evidenced by Scarlet Garcia's comment at the end of Season 2; "I still haven't figured out who you really are."
