Koopa Klaw is an attack used in the Super Smash Bros. series that can be performed by Bowser. The name originates from the characters' species, which is Koopa Troopa, or his Japanese name which is King Koopa. The move can be executed by pressing side B.
There are two different things that will happen if Bowser uses this move. If Bowser is close to an opponent, then he'll grab him or her then start to consecutively bite them. If he's farther away, then he'll simply claw them, leaving three marks in the air for a short times (as shown in the template's image).
