Magolor

Magolor is the main villain and final boss of Kirby's Return to Dreamland, also known as Kirby: Return to Dreamland or Kirby Adventure Wii, and hails from the dimension know as Halcandra. He pilots his flying ship, the Lor Starcutter.

Story
Before the game starts, Magolor tries to use the Lor Starcutter to overthrow the ruler of Halcandra, Landia, and steal the Master Crown to gain immense power and control the universe. However, he fails, his ship is damaged and Magolor flees into another dimension.

He crashes into the planet Popstar, and several key parts of the Lor Starcutter break off the ship and scatter across the land. However, Magolor meets up with Kirby, Meta Knight, King Dedede and a Waddle Dee and he convinces them to help him fix his ship. They manage to find all five missing parts and the Lor Starcutter can fly again. Magolor then decides to use the foursome to help him defeat Landia, and tricks them into coming to Halcandra and helping him.

Once Landia is defeated by Kirby and friends, Magolor comes in and steals Landia's Master Crown, reveals his intentions and flies through a dimensional portal towards Popstar. However, the four heroes chase after him on Landia and destroy the Starcutter. He then engages in a battle between his former pawns in a two phase battle, but is defeated and dies, allowing Landia to regain the Master Crown.
