Doctor Robotnik
Doctor Robotnik (full Name: Doctor Ivo "Eggman" Robotnik) is the main antagonist of the Sonic the Hedgehog series that Chris rips off for his own purposes.
History
Robotnik is briefly alluded to in Sonichu comic #0, and he makes his first actual appearance in Issue #1 as the issue's primary villain. He also makes a guest appearance in the homemade Nintendo Power magazine. Robotnik seems to be head research scientist for Giovanni where he orders around the enigmatic Bill, a lab assistant lacking a face. He is also a member of The Private Villa of Corrupted Citizens, as well as the creator of Blake, a clone of Sonichu genetically engineered to be Sonichu's superior. However, during the creation process, cherry cola was poured over the beakers and stained Blake black and made him profoundly retarded, making him Sonichu's niggo equal instead. Robotnik was last seen towards the end of Issue #9, where Robotnik, Giovanni, and Reldnahc hold Rosechu captive while Giovanni asks Sonichu whether he'll choose his girlfriend over Cwcville. He and Reldnahc are then knocked out by an unseen force (because apparently someone KO'd them from behind or something) and they have to retreat while Reldnahc shits himself in embarassment.
Purpose
Robotnik's presence in the comic initially appeared to be that of an antagonist, or at the very least a supporting character as part of the evil cabal who attempts to thwart Chris. Instead his presence only stands to reinforce that Chris has absolutely no skills in character development. The fact that he is the villain of the Sonic games also seems to reinforce the fact that Chris has blatantly ripped off a far more entertaining plot line. Hell, Robotnik even hints at the fact that Black Sonichu looks like Shadow upon his creation in Sonichu 1.
Objective
Robotnik's goal in the whole story is never really stated. It can be assumed that he just wants to be an evil asshole like everybody else. In the actual Sonic series, Robotnik is a madman hellbent on imposing his own view of utopia upon the world. In Sonichu, he just seems like a total fruitcake. However, the fact that he is fat, claims to be extraordinarily intelligent, all while being a bumbling idiot who is always defeated shows that he is actually more representative of Chris than the actual comic character of Chris.
