In nearly every single classic Mega Man game that had Robot Design contests (from MM2 onward), all of the entries came from male designers. Well, not anymore.
Gravity Man was the first (and about only) Wily Robot to be designed by a girl. The game credits his designer as Yukiko Mori...definitely a girl's name.
Even though no one bothered to explain it, Dark Man appeared in the old Mega Man animated series that ran in the U.S.
Now what bothers me about that is how could the creators know about Dark Man if they automatically made Protoman/Blues a bad guy? (Play the game and you'll see what I mean.)
In Japan, you can find a manga adaptation of Rockman 5, which more or less follows the game's story straight through, but is still an entertaining read if you can read Japanese. It was published by the Japanese manga label BomBom, and is apparently a doujinshi (fan manga).
Apparently, Rockman 5 did a very good job of convincing people that Blues was a bad guy (he isn't, by the way). In fact, it did it so well that when it came out a couple of years later, the Mega Man TV show (produced in the U.S.) decided to makes Blues one of Dr. Wily's assistants as opposed to his normal enigmatic and good hearted self.
