Professor Charles the Hedgehog (also known as Uncle Chuck) is a brilliant inventor in service to the Kingdom of Acorn on Westside Island 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 Spagonia University academic, Professor Pickle.
Chuck's inventions include the Roboticizer, which he used to save the life of young Bunnie Rabbot after she was gravely injured during Dr. Eggman's takeover of Mobotropolis. The device made Bunnie into a cyborg, but was later exploited by Eggman to create robotic slaves.(SSD: #9, StH: #259)
Research of Dark Gaia
- From a reader's perspective, this picks up from where the original pre-Super Genesis Wave continuity left off
Chuck was accompanied to Knothole by Antoine and Ben Muttski to investigate recent tremors under the earth. It is during this time that he is greeted by Sonic and Tails, the former being overjoyed to see his uncle again. 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)
Chuck eventually arrived at Spagonia, presumably not long before The Shattered World Crisis occurred. After that, things had went downhill quickly: spurred on by research towards the Gaia Manuscripts, Dr. Eggman sent E-106 Eta to Spagonia to kidnap Professor Pickle and anyone and anything connected to the Manuscripts, including Chuck. After being alerted by Muttski, the Freedom Fighters tracked down the kidnapped professors to the Soleanna Forest Zone, where the two of them where being held aboard the moving Egg Train. Despite being menaced by Eta, the Freedom Fighters rescued the pair of scientists, who informed them of the existence of Dark Gaia and the Gaia Temples. Having learned the nature of Dark Gaia's essence, Chuck was again worried for Sonic, but his nephew brushed off his concerns. Chuck later contacted Dr. Ellidy, an old colleague of his, in the hopes that Ellidy might have some insight into the crisis. (StH: 257, #258, #259, SU: #71)
Charles is a middle-aged hedgehog who bares many physical similarities to Sonic, such as blue fur (although Chuck's is a few shades lighter than Sonic's). He has a thick, grey mustache that obscures his mouth, as well as similarly thick, grey eyebrows, arching over his blue eyes. He wears maroon colored , slightly pointed shoes with two dark yellow straps and and white cuffs, and, like most other Mobians, white gloves.
An intellectual individual, Charles cares for his loved ones more than he does himself and is typically somewhat quiet, though outspoken when it comes to opposing what he believes to be wrong. 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 when it's not his fault in the first place. Always willing to provide advice to Sonic and the Freedom Fighters, he shares a close relationship with the young heroes. Bound by a high sense of duty, he is willing to put himself on the line if it means helping others.
- It's currently unclear whether or not Chuck is actually related to Sonic in the Post-Super Genesis Wave timeline. According to Ian Flynn, SEGA has mandated that the official video game characters not have any familial relations in the comic (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. Until proven otherwise, Charles shall continue to be listed as Sonic's biological uncle.
- In the animated series, Chuck was also known as Dr. Hedgehog. This name would later be adopted for Chuck in the post-Super Genesis Wave timeline, making him Dr. Chuck the Hedgehog.
