At The End of the first world, you will have to face off with King Dedede, the greatest nemesis of Kirby. At first, King Dedede won't seem like all that much; however, as his health starts to get low, he will actually transform into a giant monster. After turning into this buffed form, King Dedede will stomp on the floor, creating two separate lower arenas by doing so. At the bottom of the tower, King Dedede will begin swinging poles at Kirby and his Friends. If you want the best shot at defeating King Dedede, use the Cutter Copy Ability and combine it with one of the Elements.
