Monokuma from the Danganronpa series. Series 1 is game or TV anime. Series 2 is game only. Both versions of Series 3 (meant to be watched in alteration(ep 1 of one series, then ep1 of the other, back and forth). V3 is game only.
sorry if i'm kinda elitist, but shonen edgy anime (pretending to be seinen) starred by teenagers are the worst examples to defend your case...
-danganronpa: i can give it a pass mostly by the concept
-naruto: good start, crappy ending, darkness(tm) all the way
-boku no pico hero academia: it's green naruto with liberal ideals
-mirai nikki: kinda cringey love story with edgy yandere waifubait
-eva: too mainstream
-elfen lied: sorry, but that was a crappy story only sustained by edgyness and tiddies
you should have selected something deeper like: shimoneta to iu gainen, serial experiments lain, black lagoon, welcome to the nhk, ghost in the shell...
