Hey hi there Deadset Future! Welcome to Void!
Dude, I'm totally sold for this kind of dystopian apocalyptic cyber/biopunk trope, so I'm very thrilled to get to know your character better!
Kozispoon made a good observation about the Specimen 8's "cleaniness", but I see you got that already covered, so I'll just address 2 other points:
Worldbuilding - develop your O.C as much as you want, but don't forget to develop also the world he lives in, as most of the times the story's protagonists are a consequence of the world they live in.
Overpowered - Comics are comics, and at the end of the day, anything can happen if one let the imagination run wild, this isn't even an issue here, because a good writer/comic creator can overcome the power level discrepancy between O.C's thing...what I'm saying here is...I see your guy has a vast set of powers, clearly he means real business ( even with the limiter device! ), but does he have weak points? any factor which could possibly be exploited? If he’s just a pawn, how do his high ranked superiors control him? and does that mean they are way more powerful than 8ball..? Whoa, I'm super curious to hear your thoughts!
Art wise I like your art style, you've got a good anatomy sense IMO, can't wait so see your intro pages man!
Hey, one more thing: have fun!!
Yes due to the way he interacts with other characters in his world, and the nature of the world he lives in he might be considered op but as you mentioned it he isn’t the most powerful. But I will update it with some of his weaknesses I failed to mention. Im glad this is what the incubator is for, thank you for your feedback
