Well, just in case, allow me to refresh the memories of all who come here for the next two or three years, and possibly more.
Megaman (Rockman) is a blue robot created by the famous Dr. Thomas Exavier Light. He first however, build a robot named Protoman in cooperation with his assistand, Dr. Wily. Dr. Wily then stole that first Robot, known as Protoman (blues) and six other environmental robots that Dr. Light created to take over the world.
Megaman then beat all of those, and the same process repeated several times throughout the series.
MMBN is a side series about a computer program named Megaman and his owner Lan. There\'s not much I need to say here.
Megaman X is believed to be Megaman only upgraded (still arguing). He has a friend named Zero, and a new (maybe) apprentice named Axl. He\'s a maverick hunter who hunts down \'bad\' reploids, which are robots that can think for themselves. His arch-nemesis is known as Sigma.
Megaman Zero is based about a century after megaman X, which is based about a century after the original. It delves into Zero\'s life fighting with humans and machines to help defeat....well, I haven\'t played MMZ2 yet, so I can\'t tell much about that.
Megaman Legends is based a LONG time after any of the series (not counting MMBN), about a (robot?) named Megaman Trigger looking through ruins for power sources. That\'s just about it. There isn\'t more to say.
Hope this helps.
And whitefox, don\'t forget to read my PM.
