The movie was entertaining to watch and had an interesting story. A couple things confused me though. Why was Megaman there? It looks like the X universe but with Megaman present. I'm guessing this is around the time the Reploid rebellion started? When I saw the video thumb, I thought this was going to be a story of X's creation or decision to fight against the Reploids, so I'm not really sure how this is the origin of X. Otherwise I liked the movie, just those two parts confused me at first. Just suspending disbelief for the rest of this because the story looks really good.
I'm looking forward to some more fight scenes. As a suggestion, since Megaman, X, and Zero can steal their opponent's powers, you should have them absorb some of those four's abilities and skills. In a lot of the Megaman movies I've watched, the power absorb trait is always left out and I think it would be cool to watch Megaman turn the tables on these guys after getting beat up by touching one and stealing his skills. I also liked how they could trade energy with each other. That was cool and unique to me. Keep it up!
