There's not much continuity to the storyline, basically it's introducing all of the major characters. The World Three members each take a crack at causing mayhem around the city in various ways, and each time are defeated by Lan Hikari and MegaMan. Lan also meets Chaud for the first time, while MegaMan and ProtoMan become acquainted with each other. It should also be noted that NumberMan is evil in this manga, and a member of the World Three like the games. ShadowMan is also included, but he seems to be an ally of MegaMan.
