A demon is edgy.
A cyber demon is campy.
A cyber demon that rides a space motorcycle and consumes souls is amazing.
Edgy characters are meant to be taken seriously. They're characters that the player wants you to be terrified of because of how real they are man. Gore, mutilation, death, and rape are all tools the edgelord loves to employ but are ultimately pointless without some form of emotional investment and when halfassed writers throw them out like charity they become lame. This is the hallmark of the edgelord.
Resolution is as far from that as you can get. He's an awesome character yes, but the inherent ridiculousness of the concept backed by Nega's skill as a writer are what make him awesome, if you're approaching him the same way you'd approach late-00's Batman movie you're completely missing the point of the character. He's early-90's Batman and is awesome because he sees your grit and he jumps over it with a motorcycle while hollering at the top of his lungs. Even in character Resolution isn't exactly serious, grabbing someone's phone doesn't change that, my little sister does that all the time and it's not edgy so much as annoying.
It's the difference between Devil May Cry and Resident Evil. The later wants you to revel in it while the former wants you to laugh at it.
