Hitmonlee appears as a Pokémon that comes out of a Poké Ball in Super Smash Bros.. Hitmonlee uses Hi Jump Kick as its attack. Hitmonlee will remain motionless for a full second, then it will extend its leg and jump in the air at a randomly decided opponent target to inflict heavy damage and knockback if it connects. Its attack can't harm the summoner.
In the American release, Hitmonlee retains his Japanese voice instead of being dubbed like in the anime (The same thing happens to Cyndaquil and Marill in Melee). No information has been given to why this occurs.
Scizor replaces Hitmonlee in Melee. Scizor's attack is different from Hitmonlee's in that it will slash multiple times, while Hitmonlee only kicks once.
