This is a tribute to Batman vs Robin! Oh no, I’m not about to say that Megaman can defeat Batman am I? Well…..yeah, that’s basically what I’m about to say. Megaman is even stronger than the mighty Son Goku thanks to his manga series and there’s no way that Batman could hope to keep up with Megaman’s speed or power. Megaman is simply too powerful and he has many super forms that increase his abilities even further. Megaman wins.

Megaman isn’t stronger than Goku, Goku has Super Saiyan God Super Saiyan form. It goes beyond Super Saiyan God form.
That is true and it did help Goku get even stronger so it is a very close fight. I still think that Megaman has the slight edge thanks to his speed though, but I haven’t actually seen the full Rebirth of F film yet so I can’t be certain.
