Impa is a non-central character but her name is mentoined alongside Link's and Zelda's to have a special meaning in Hyrule Historia.
Sure. Original holder of the Triforce of Power, been around the series since the NES days, first ally of Link in Hyrule Warriors (first announced second playable character alongside Link even), having a major revival role in Skyward Sword, NOT being a ****ing one-off whilst staying prominent in the series and NOT named Link, Zelda or Ganon...
Sure, Impa has no merrits to be in Smash.
This has been disproved too many times. And yes, Ganondorf needs a new moveset, what the **** else is new?
Also, all Specials are supposed to be offensive, yet we have a trillion Counters and Reflectors... DA **** IS UP WITH THAT!?
