As always, Nintendo is coming out of the gate swinging with today's Super Smash Bros. Ultimate Direct. Announced as the final new challenger, Pokémon Sun and Moon's Incineroar is joining the battle. Featuring powerful throws and attacks based on the Pokémon moveset, Incineroar is strong but loves to showboat a bit. After successful attacks, Incineroar will pose for the audience (though you can cancel it at any time). With Incineroar's reveal, the final roster count stands at 74, barring any potential future DLC.
