sauvignon1: I've getting into the Crossed series originally started by Garth Ennis, particularly the webcomic
Wish You Were Here . It's a no-hold-barred looks at survivors in a world infested by rape zombies (seriously) and shows people at their absolute worst. So what's your candidate for meanest comic?
Think I have something for you:
Becchin to Mandara (aka Velveteen & Mandala) by Jiro Matsumoto
Also has rape zombies, plus Japanese high school girls in post-apocalyptic Tokyo. I've read a couple 10'000 pages worth of comics but this one definitely sticks out as one of the extra weird ones.
Also check out
Freesia by the same author, Jiro Matsumoto's art style may not be everyone's cup of tea but it is refreshingly unique, takes a bit of getting used to. Freesia is one of my all time favorites, completely and utterly nihilistic and cynical to the bone though so it's not for everybody.
