I totally remember this. I think these comics were the first ones that I ever owned, which was weird since I got these comics years before I had any idea what the word amalgamation meant (I still think it’s a super weird looking word. Those letters just don’t belong next to each other).
Also, Wolverine/Batman has got to be the scariest, most messed up badass ever concocted.
