Get it right!
Well, without going into detail about the animation's other strenghts/weaknesses, there was one thing in this animation that really bothered me. The character that you kept calling "Zero" is not Zero! In fact, the character Zero is not even in the classic megaman games! He's only in the Megaman X series. The guy you kept calling Zero is actually called Protoman. If you're going to make a retro video game animation, you can at least get the character's names right!
