If there's one thing I love, it's mash-ups! Thepic you see above (Super Mario Warfare) was created by Deviant Art-ist Agent Scarlet, and imagines a world in which Nintendo's mascot crashes full on into Modern Warfare. Big ups to its genius creator. According to the artist:
"Peach is now a scientist that gets kidnapped all the time
and Mario is a veteran spec ops commando."
Check out all of Agent Scarlet's stuff for some interesting takes on Metroid, Team Fortress and more. Seriously, click it; you'll spend a half a day there.
