Kip. 49: Gaikotsu Change!

49

Using the power granted to him by the comet, Crown enters a museum and begins fusing with dinosaur skeletons. Geo happens to be there on a field-trip and fights back as Mega Man. However, since Omega-Xis is still incessantly polite (due to the comet), he becomes uncooperative in battle. Eventually, the comet passes Earth and the effects on the FM-ians subside, marking one more victory for Mega Man. (Source: Wikipedia)
