Oshawott (ダイケンキ, Daikenki) appear as a newcomer in Super Smash Bros. Revolution, revealed at the end of the Direct of Ultra Pokkén Tournament.
Oshawott is confirmed to have no alternate costume.
Oshawott's Shell Armor ability comes into play here. It prevents Oshawott from taking critical hit damage from attacks (with the exception of Final Smashes, including Marth's Critical Hit). Like its Pokedex entry in Pokémon Y, Oshawott will immediately retaliate when attacked by slashing with its scalchop, which is exactly what it does in its down special Revenge, which functions as a counter. Oshawott has Squirtle's neutral special from Brawl and it works exactly the same way. Surf was Oshawott's move back in its Pokeball days. It works the same way, except it can be cancelled by pressing the button again and Oshawott can jump to attack in the air if started on the ground. Oshawott's up special Aqua Jet gives Oshawott Super Armor during the attack.
