Warning: This post contains potential spoilers for Super Smash Bros. secret characters on the Wii U.
We've seen some of these before, in a comparison of veteran characters' final smashes from Super Smash Bros. on the Nintendo 3DS and their corresponding moves in Super Smash Bros. Brawl. This video by GameXplain however, catalogs the final smashes for all 51 characters in the game.
Super Smash Bros. for Wii U launches in North America on Nov. 21. For more on the game, see this video of its 8-player mode.
