You can start to study up for the upcoming release of Super Smash Bros. Wii U with this compilation video of final smashes for all 51 characters in the game, compiled by YouTuber GameXplain. Familiar friends like a winged, fire-breathing Yoshi and Mr. Game & Watch turning into Cthulhu are joined by new sights, like Mega man ganging up on his opponent with alternate versions of himself and Pac-Man transforming into a ravenous, two-dimensional nightmare.
Note that while there is nothing new shown here that has not been revealed elsewhere, but of course the video contains spoilers of unlockable characters:
Super Smash Bros. Wii U arrives soon on November 21, 2014.
