Magolor comes from the planet Halcandra and captains the Lor Starcutter starship. One day, he crashes his ship on Planet Pop Star, this destroys the Starcutter, spreading it's parts across Pop Star's many territories. He is eventually discovered by Kirby, King Dedede, Meta Knight, and Bandana Waddle Dee. He asks for their help, originally coming off as an unlucky captain. After Kirby and co. fixes the Starcutter, he takes them to his planet of Halcandra, but he is shot down by the dragon Landia. After Kirby defeats Landia, however, Magolor shows his true self, an evil, greedy monster who wants to take over the world. The only thing that was stopping Magolor from reaching this goal was Landia, who was guarding the Master Crown. He pretends to congratulate Kirby on taking down Landia, but then grabs up the Crown and throws it on his head. He completely changes his look, and reveals that he originally attacked Landia, but was beaten, so he crashed the Starcutter on Pop Star. He then met Kirby, and used him as a soldier to take down Landia. He then opens up a wormhole, and flies off, bent on taking over the universe. Kirby and co. awaken Landia, and chase Magolor down. They follow him to another dimension, and He attacks in the Dark Starcutter. They destroy the Starcutter, and fight Magolor. After the battle, he falls, only to rise up again in a more demonic form. Kirby and Co. then fight him again and beat him, this time for real. He falls, and the Master crown is destroyed. Magolor reverts back to his normal form, and disappears.
Despite his apparent destruction, When the player gets 100% completion, He appears to congratulate the player.
