Game Boy's (VERY) prototype sprite for Mega Man 2.0. He's, well, a Game Boy. In his battle, different buttons flash or his screen shows a picture or words that tell you which attack he's about to do. If @UnderKoopa757, @powerninjacreator2, or @nivock can resprite this, that would be great. Use the Game Boy color palette that's in there.
Pixilart.com. It's really good (and free) so try it. Nintendo, for, well, the Game Boy console that gave me inspiration.
