Since moving to the SNES 16-bit land, Mega Man has taken the secret identity X, but everyone knows it's still him because he's the only blue robot who shoots three pellets at a time at other robots and steals their weapons.
For extra curiosity, there is a page "Mega Man X Tricks"
that explains some of the tricks that are and/or can be
used in the X series games.
This video takes no damage except where it belongs to the plot... sort of. You'll see.
