Sir Charles the Hedgehog


 * For other uses of the term, see Chuck.

Professor Charles the Hedgehog, often called Uncle Chuck, is a brilliant inventor in service to the Kingdom of Acorn and is the uncle of the world hero, Sonic the Hedgehog. Charles is a well known genius who has always used his research and inventions for the good of the world. He is also a friend and colleague of famed academic, Professor Pickle.

Back On The Field
Following the drastic alterations to reality on Mobius, Uncle Chuck ended up out in the field once again. Accompanied by Antoine, he and Muttski went Knothole to investigate the recent tremors. Sonic and Tails, who are looking for Antoine, comes across Chuck. The good doctor's greeting is interrupted by Sonic's joyful embrace, and the overjoyed hedgehog thinks how Sally no longer being a robot, Knothole not being destroyed and Uncle Chuck still being around are making him prefer the new universe to the old one. A surprised Chuck asks Sonic what's gotten into him, and he tearfully responds that he was just happy to see his uncle safe and sound. Chuck replies that no one will be safe if he can't figure out what has been causing the recent tremors, which he believes to be Eggman's doing. He has been collecting samples of some sort of purple energy that's been seeping out of the cracks in the earth, and requests Nicole's assistance in analyzing the samples if she's free. The damaged supercomputer apologizes and says she is needed elsewhere, albeit with a garbled signal, prompting Chuck to ask about her condition. Tails says it's complicated, while Sonic replies that they need to see Antoine to help fix her, and Rotor said he was here. As if on cue, the new and improved Antoine walks up to them with a small Mobian dog in tow, and remarks that he was not expecting to see Sonic and Tails here. The two friends immediately hug their rejuvenated comrade, confusing him somewhat with their seemingly unwarranted elation.

Chuck once again asks Sonic if he's feeling okay, and the latter replies that he's just happy to see his buddy again, much to Antoine's confusion. At the same time, the Mobian dog is happy to see Sonic and Tails again, though they don't seem to recognize him. When he refers to himself as "The Mutt", a surprised Sonic suddenly asks if he is Muttski, to which he confirms, having been transformed from a regular dog to a full-blown Mobian dog known as Ben "Mutt" Muttski due to the effects of the Genesis Wave. Noticing Sonic and Tails' shock and confusion at the revelation, Antoine asks why they are acting so "funky", to which Chuck surmises that they might've had some spoiled chili dogs on the flight over. He then tells Sonic that he and Ben have work to do, and that they should leave with Antoine. (StH: 254)

Later, Uncle Chuck and Professor Pickle were kidnapped by Dr. Eggman, as the mad doctor wanted to put the planet back together on his own terms. (StH #257) Sonic and the Freedom Fighters find the two professors, but E-106 Eta found the professors' compartment. Sonic fought the robot, and with the help of the rest of the Freedom Fighters, successfully rescued Uncle Chuck and Professor Pickle. However, due to Professor Pickle forgetting to remind the Freedom Fighters to collect the research and Uncle Chuck being knocked out, the research went into the Eggman Empire's hands. (StH #258, StH #259)

Sonic the Hedgehog (TV series)
In the television series, Sonic the Hedgehog, Charles was a knight and scientist in the service of the kingdom, until Dr. Robotnik stole his invention, the Roboticizer to enslave Charles' people, making Charles unwittingly responsible for the rise of Dr. Robotnik. Charles himself was captured by Robotnik and was one of the first to be roboticized, becoming the doctor's mindless slave, an event that drove his nephew Sonic to become a Freedom Fighter.

Over the next ten years, Charles served as the mindless worker bot in the service of Robotnik. Eventually, though, after a failed attempt to deroboticize Charles, Sonic managed to help Charles retain his mind and free will. Charles then remained undercover, working as a spy for the Freedom Fighters while pretending to still be a mindless slave, up until Robotnik's defeat.

Sonic Underground
In Sonic Underground, Chuck was Sonic's uncle. Following Dr. Robotnik's takeover, Chuck became a high-ranking member of the Freedom Fighters stationed in Robotropolis: When Sonic's adopted parents was arrested by Robotnik, Chuck took Sonic in and raised him on his own. Chuck eventually got Sonic into join the Freedom Fighters, and the two of them worked together on sabotaging Robotnik's factories. He was eventually captured by SWATbots and roboticized shortly after Sonic found his siblings Sonia and Manic.

Personality
An intellectual and patriotic Mobian, Charles cares for his family more than he does himself. However, he is quick to be hard on himself for his mistakes, often to a point far beyond what he should lay on his shoulders, even though is not his fault in the first place. Always willing to provide advice to Sonic and the Freedom Fighters, he is something of a father figure to his nephew and shares a close relationship with the other young heroes as well. Bound by a high sense of duty, he is willing to put himself on the line if it means helping the Kingdom of Acorn.

Because of the relationship between him and Sonic, Sonic will do anything to save him even if it seems reckless.

Physical Appearance
Chuck has blue fur with tan arms, chest and muzzle, deep brown eyes and bushy grey eyebrows and a mustache. He has black eyes with red pupils (roboticized version only). In the Archie comics series, his eyes are now blue.

Trivia

 * Although Uncle Chuck first appeared in StH #16, he was actually mentioned in the first issue.
 * According to Ian Flynn, Sega has mandated that the official video game characters not have any familial relations in the comic, meaning that Charles is no longer related to Sonic in the Post-Super Genesis Wave timeline (this rule was first enforced in the original continuity, and Ian got around it by having previously established relations not being directly stated as such). On the other hand, Sonic continues to refer to him as "Uncle Chuck", though this could simply be as a sign of affection due to how close they are.
