Mega Man's primarily extremely courageous and just, choosing to become Mega Man and face the threat Wily posed because he wanted to help and do the right thing. This said he's also a pacifist and in the Mega Man Powered Up pre-boss cutscenes he always tried to find an alternative to violence. This trait was also, to a degree, shown in Mega Man 8 where he questioned Bass as to why they must fight. Along with these traits he's also kind, generous and polite.
Another feature to boost re-playability is the manual drift. All Mario Kart games had a power-slide around corners. In this one they give the choice of this drift being automatic or not. If you set it to automatic you don't get mini-boosts around corners. If you set it to manual you have to time when the slide starts but it is much more difficult than past games. It gives experienced players something extra to work on but doesn't seem unfair when somebody can drift manually well.
However, Wily's frequent false repentances have become a constant frustration to Mega Man who appears to developing less patience with him, something that came to a head in the course of Mega Man 7 where he contemplated killing him, though ultimately decided against it. He further pointed out Wily's previous false repentances at the end of Mega Man 9, showing his diminishing patience, however he nonetheless assists him when he becomes ill in Mega Man 10.
Though Capcom owns the rights to all Mega Man games and has been responsible for the development of all of his console titles, it has in the past licensed the Mega Man character to other companies for PC releases. Mega Man and Mega Man III (with no relation to the NES games of the same name) were developed by the US-based Hi-Tech Expressions, the Mega Man game published on the Game Gear by Sega, and Rockman Strategy was developed and released exclusively in China by AcerTWP. Neither title has since been regarded by Capcom as an official Mega Man series game.
