So what do you call a spoof of a spoof? Dead-Pooh. That's right - Winnie the Pooh reimagined as Deadpool.
So this leads me to think... what other mashups can we come up with? Here are my initial offerings:
Bugs Bunny + Batman = Batbunny
Popeye + Hulk = Hulkeye
Smurfs + Marvel Mutants = X-Smurfs
... Hmm... I guess that last one really wasn't so different after all.
