The webcomic "Breakfast of the Gods" by Brendan Douglas Jones is a
pitch-perfect spoof of contemporary grim'n'gritty superhero crossovers like (mostly) "Identity Crisis" and (a little bit) "Infinite Crisis" and "Civil War" — featuring old-school cartoon cereal mascots.
My favorite part is where the crazed Frankenberry beats the Honey Nut
Cheerios bumblebee to death in Count Chocula's dungeon. Also the scene
with Sugar Bear out by the pier, where he's all Wolverine-ish in his
attitude, drinking beer and bitching about how hard it is to carry a
beast around inside him.
