Anti-Kirby

Anti-Kirby is a species found in the Game Boy video game The Legend of Zelda: Link's Awakening. They look almost identical to Kirby, a character in a different video game series. Just like Kirby, he'll suck any of his opponents in, thus harming them.

The only way to kill them is to attack a Magic Rod or a bomb. You'll find the species in Eagle's Tower. It should also be noted that in the Japanese version of the game, the Anti-Kirby are just called Kirby.
