Defeating an enemy with a non-buster weapon in the Japanese version of the Mega Man Zero series would make robot characters spout out something resembling blood. It was removed in the US/European versions. Oddly enough, the rating for the Japanese version of the Mega Man Zero series were unaffected.
Rockman.EXE WS is a side-scrolling platformer in the same style as a classic Mega Man game. It's based on the first two seasons of the MegaMan NT Warrior anime. It was released for the Japanese-only WonderSwan Color, but an English patch has also been released online.

Keiji Inafune, who is often called the father of Mega Man, did not actually create him. Inafune's mentor at Capcom, who was the designer of the original Mega Man, gave Inafune a basic concept of what Mega Man was supposed to look like and he was tasked to clean up the concept for use in the game. Inafune didn't get to completely design a Mega Man protagonist from scratch until Mega Man X, where he created Zero.

The Battle Network and Star Force series are an alternate timeline, separate from the classic series, X, and so on. Instead of building robots which led to the Robot Apocalypse, Dr. Wily and Dr. Light (who is Dr. Tadashi Hikari in the Battle Network games, his name meaning 'Right Light' in Japanese) created the internet which led to taking advantage of electromagnetic waves in the Star Force series.

According to Keiji Inafune, the decision to make Mega Man blue was based on the fact that, out of the 56 colors that the NES color palette has, blue has the most variety. This helped show off his moves as they could be more detailed.
