In the Ruby-Spears Mega Man animated series (as we like to call it, as it sounds more professional and sophisticated that way), one of the best moments in each episode was usually when our hero would suddenly swipe the powers of his enemies and use them to turn the tide. Part of that was due to the cool weapon diagrams, part of it was due to the instrumental version of the theme song kicking in, and part of it was just seeing how creatively they interpreted/how badly they screwed up some weapons. A couple of years ago (as it turns out), YouTube user JadePharaoh put together a compilation of these moments and set it to some nice remixed Mega Man music. Check it out:
Of course, there are three moments which stand out among these. One, of course, is in "Electric Nightmare," when Mega Man steals Pharaoh Man's weapon (kind of surprised they didn't end on that), another is from "The Beginning" when Proto Man joins in, and the last is from "Mega X", when X gets in on the action-- in triplicate! Too bad that last one didn't make the cut, though.
