The Superest is a fairly new site by illustrators Kevin Cornell and Matthew Sutter, with occasional guests. The site is an ongoing game of My Team, Your Team. The rules:
Player 1 draws a character with a power. Player 2 then draws a character whose power cancels the power of that previous character. Repeat.
This results in some very, um, different superheroes. Like Albinis the eyeless albino tortoise, The Chlorinatrix, and Hot Shave Carl the Barber. The current leader is Brocco-Lee, but that won’t last long. Link -via Metafilter
I give to you... Retarded Ninja
Giant man-eating bunnies, singing forks, etc. Heh.
Some characters were lost to spilled paint or covered/modified by other bored students but most are still on the table 2 years later
