Nothing in this video belongs to me, and I mean nothing!
THIS VIDEO IS NONPROFIT!
Mega Man/Rock Man belongs to Capcom
I used http://www.wevideo.com to pick and tuck this awesome anime intro for Mega Man.
To explain EVERYTHING, "Mega Man Megamix" and "Mega Man Gigamix" are wonderful taigadramastyle Mega Man manga created by Hitoshi Ariga (using Capcom's characters and designs)
This animation was made by a fan of his named "Panman", who took a lot of time to make a parody of the "Namco X Capcom" Intro (Brave New World) the full video can be found here (at NicoNico Douga) http://www.nicovideo.jp/watch/sm22844598
The song is from the Rockman Holic Soundtrack and is named "Together As One", a remix of Dr. Wily Stage 1 (Mega Man II) by 'nano'. I'd buy the music but it's impossible to get (I'm American, it's from Japan; hard to get)
So other than that, all the characters scene in this video belong to Capcom.
