Answer: Mega Man

Many a young video game enthusiast has doodled a character idea or two on the back of their school notebook. If you were a fan of the Mega Man series, however, there was actually a chance your doodling would come to pixelated life.

After the success of the original Mega Man game and the enormous amount of fan enthusiasm, Capcom started holding contests before the release of every new Mega Man installment where fans could submit their ideas for new batches of Robot Masters that Mega Man could fight. All the bosses from Mega Man 2 through Mega Man 8 were fan submissions.
