Archie Comics has quite a contest for fans of the Mega Man comic series with some artistic talent -- all you have to do is submit art that "showcases Mega Man and/or his universe."
If you win, you'll be featured prominently in Mega Man issue #23, plus you'll get every issue of Mega Man so far, the Mega Man tribute art book (which is excellent by the way), and a Capcom Unity prize pack.
You can submit your art to firstname.lastname@example.org, and find the full rules and regulations listing at Capcom Unity's site.
If you're an Archie Comics fan, you can also nab this deal for $60, which nets you one year subscription to the Sonic the Hedgehog, Sonic Universe, and Mega Man comics.
