Mr. Stewart (スチュワート Suchuwāto?) is a character in the anime series Sonic X and its comic series published by Archie Comics. He is a human government agent working undercover as a school teacher assigned to watch Sonic the Hedgehog and his friends by the President under the code name "Chalkboard Charlie". As an agent, he owns numerous gadgets, including a green-blue spy car, which can transform into vehicle for water travel.


Stewart is a fairly regular human with neck-long blond hair and wears a blue coat, glasses, a turquoise vest, a white sweater, and dark grey pants.



New World Saga

He taught Christopher Thorndyke and his classmates, including Danny, Frances and Helen. Mister Stewart always looked out for the kids in his class.

Chaos Emerald Saga

Chaos Saga

The kids weren't so sure about Mister Stewart at first until Episode 32, when they started to display a likeness to him, especially as he helped get them to safety during Perfect Chaos' attack on Station Square.

Shadow Saga

Having ditched his mission to help his students at Station Square Elementary School, Steward was given a new alias and assignment- to pose as a News Director and investigate Project Shadow - in the episode immediately following.

Egg Moon Saga

Mr. Stewart furtively entered the White House through a secret passage. His mission was to save the President, whom had been captured and taken hostage by Dr. Eggman. Stewart freed the president and his secretary and put an inflatable doll in his place. Eggman was tricked and covered with the doll instead of the real president. Thanks to Sonic, he defeat Eggman.

Emerl Saga

In the Chaos Emerald Martial Arts Mash-Up, 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 adaptation, so he forfeited his match with Lucky, saying "My cover has been BLOWN!"

Homebound Saga

On the day of the execution of Project Homebound, Mr. Stewart contacted Topaz and the commanders of GUN to go rescue the president who was imprisoned in his office by the agents dressed in black. Eventually, the campaign succeeded. After this event, Mr. Stewart and Scarlet watched from a distance how Sonic and his friends were returning to their world. Scarlet suspected that Stewart might be a government agent, but decided to keep the truth about himself secret.


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."

Powers and abilities

Mister Steward is skilled at hand-to-hand combat, being able to defeat several trained human agents single-handed. He is also good at basketball; he says he was an alternate on the practice squad back when he was in College. However in the Japanese version, he just states that he was good at the sport back in the day.
