Kracko is a recurring boss in the Kirby series. He is a large cycloptic thundercloud with multiple yellow spikes jutting out of his body. Kracko's attacks mostly revolve around lightning and electricity. Kracko's first appearance was in Kirby's Dream Land, and he has since appeared in almost every Kirby game to-date.
In Kirby Star Allies, Kracko is unusual. After he is beaten in his first phase, he duplicates himself and he and his duplicate become Twin Kracko. Kracko also has his own counterpart in the Heroes in Another Dimension sub-game.
In Kirby Air Ride, Kracko appears in Top Ride mode as an item that, when collected, summons him to perform powerful lightning attacks on opponent racers.
