In the past in Mega Man X games, X used to do all the real fighting, while Zero said he was off to destroy power sources, and other such unverifiable tasks. Zero even had the audacity to tell X that one day he'll be as strong as Zero.
This time X lays back and relaxes while letting Zero go put his moneylightsaber where his mouth is. This leaves Zero to fight off an entire army, as well as Sigma. Zero does such a good job showing how incompetent X is, the series has been transformed for TASVideos to be a Zero series from here on out.
