Super Punch has a round up of the best, my favourite has to be Katie Cook‘s Spider-Cat:
Closely followed by Lar Desouza‘s Hulk, Skottie Young‘s Venom and Mike Maihack‘s Ghost Rider:
In related news I’ve ordered Marvel Zombies 1 (as well as the first volume of The Walking Dead) and am about to settle down to a spot of Gotham by Gaslight (Batman vs Jack the Ripper co-written by Mike Mignola).
