The idea came after 10 houres non-stop gaming... It was around the time when I was playing "Mega Man Battle Network" in 2003. I just love the games (series 1-3).
Arkanus was originally not planned in that animation, but I found a suitable head to fit in. I too did plan to make Ark's body look blue like MegaMan's. But it would be too much copyrighted shit...
