what is the most edgy series to ever exist
Dragon ball z
Bleach and Naruto both revved up to DBZ levels in certain arcs along with most of the shounens that have had the largest followings.
Does yugioh count? yugioh and beyblade are awfully edgy. Look at the hair, it's almost always a dead giveaway; say spike for each hair spike a character has and if "spike" feels like it's lost its meaning the show is probably drivel written for prepubescent boys following the same story arc of hype and padding that DBZ pioneered.
