Birky

Anti-Kirby (plural form: Anti-Kirbies ) is an enemy in The Legend of Zelda: Link's Awakening and its Game Boy Color port, The Legend of Zelda: Link's Awakening DX. They are directly inspired by Kirby from the Kirby series, and have the same appearance as him. Anti-Kirbies are purported to be the evil twins of Kirby, though their Japanese name seemingly identifies them as the character himself, despite there being more than one in the game. Anti-Kirbies have the same inhalation ability as Kirby.

Anti-Kirbies only appear on the first floor of Eagle's Tower, where they jump around the room in random directions. If an Anti-Kirby notices Link, it tries to inhale him into its mouth. If an Anti-Kirby successfully inhales Link, it spits him out a few seconds later, causing Link to lose a Heart. Anti-Kirbies are invulnerable to some of Link's attacks, including his Sword. Link can only defeat an Anti-Kirby by using the Boomerang or the Magic Rod, or by throwing a Bomb to explode near it.
