For those who don't know, Megaman 5 on gameboy is completely different than the Nes version; It has a whole different story with completely different bosses, etc. It is also the first of very rare appearances of Tango, Megman's feline animal companion. Bosses in the game follow a solar system theme with each of them representing planets.
If you're a big MM fan like me, you are probably familiar with or at least even heard of the manga "Megaman Megamix" by Hitoshi Ariga! I love his stuff! >.< He posted this video a while back (I think it might be him because the poster uses his name and avatar on youtube =x) I've never gotten to read the final half of his MM comics, but from what I've seen, it involves space and the space robot masters. XD I was really stocked when I first found the video, but then Alex recently getting MM5(GB) and me seeing the video later made me realize that it's probably briefly based on the the manga! =D The Wily, Cossack, and Light forces teaming up against the space robot masters!! XD so awesome!!
The video is pretty much the opening to NamcoXCapcom for the PS2, but redrawn to be themed to Hitoshi Ariga's comics! Enjoy!! XD
Here's the original if you want to compare. so awesome!! >.< Too bad it's sooo hard finding a good HD version of it. -_-
