We live in a world where, sadly, there is no such thing as a Rockman Gigamix anime. If there was one however, it would look a lot like the above. Hitoshi Ariga, the man behind Gigamix, gave his blessing to this fan-made mock anime opening, largely influenced by a similar scene from Namco X Capcom.
If your heart can take it, it's well worth the watch. Pure magnificence.
Thanks for the tips, Eric and Shin!
