Copy Abilities

In every Super Smash Bros. game, Kirby has the ability to copy another character's neutral special move with his own neutral special move, Inhale. If Kirby swallows another Kirby, only damage is dealt, but if he swallows another Kirby that has a Copy Ability, it can be stolen. When Kirby copies an opponent, he will also bear a resemblance to that character, usually in the form of a hat that displays a prominent visual part of the character copied. When performing copied attacks, Kirby often mimics their voices or sounds as well as their poses, and uses the same weapons as their owners; however, unless otherwise noted, alternate costumes have no effect on his Copy Ability. Aside from the obvious range differences, copied attacks are functionally identical to the originals except where noted.

Kirby can discard the ability at any time by taunting. He may also lose it when taking damage (though there is a temporary "grace period" where this will not occur), and he will also lose it upon being KO'd. Also, anything spawned by the ability will vanish if Kirby loses it. For example, if Kirby tosses a Metal Blade onto the ground, picks it up, and taunts, the blade will vanish. Kirby will also lose his ability if the inhaled character's damage meter vanishes (indicating the character has been unloaded from memory), such as in Smash 4's All-Star Mode or certain Event matches. Kirby will keep any Pokémon Trainer's Pokémon's ability, even if they change Pokémon.

In Ultimate, when using his copy ability, Kirby gains a 1.2x damage multiplier for the copied move; however, knockback is not affected.
