Another thing I forgot to mention: NOISE CRUSH. Mega Man fires supersonic soundwaves that are already incredibly loud and destructive, but if it's rebounded back at him, he'll absorb it and fire an even stronger blow. This would DECIMATE Astro, what with his super-hearing, and put him at a bit of a disadvantage. Though, I'm not sure if it would be enough to put him down for good.
