The first batch of news out of the final Super Smash Bros. Ultimate Nintendo Direct is that Ken from Street Fighter and Incineroar from Pokémon will be joining the roster. These are confirmed to be the two final characters appearing in the game. The rumors about Banjo and Geno were big ol’ lies.
Ken is an echo fighter of Ryu. He has a heavier Shoryuken with a different shape, and his whirlwind kick hits multiple times. He has two Final Smashes like Ryu, and he moves a bit faster than Ryu. Incineroar can do a Cross Chop, which is powerful but leads to easy self-destruction. In general, he seems to have a lot of vicious, in-your-face moves.
