You shouldn't make your comics quickly. Take your time on writing the comic first. Then, once you have it all written out, use the spell check. Also, please get a storyline. A random battle is not a storyline. You must lead up to why they are fighting. Otherwise it's just random fighting.
In the comic, you should've just had three lines where Protoman was, and have the full Protoman sprite behind Mega Man.
That sprite doesn't look like Protoman at all. It just looks like a MM recolor. There are multiple sprite sites like
The Spriter's Resource to help you.
Good Night, and have a pleasant tomorrow.
