Great Character Crossovers by Frankie Perez
Stumbled upon the work of Frankie Perez on Tumblr and just had to share. The mash-ups may be simple to think up but the execution is incredible! The crossovers span the world of comics, movies, anime, and gaming. My personal favorite is Hellboy meets Loki, although Terminator and Venom are an extremely close second.
Iron Man Meets Big Daddy (Bioshock)
Assassin's Creed meets Superman
Majin Buu Meets Green Lantern
Joker meets Captain America
Loki meets Hellboy
Terminator meets Venom
