Ridley (Metroid Prime 3)

Ridley, also known as Meta Ridley, is Samus's primary enemy. He is a giant dragon-like villain and is the second most recurring character, second only to Samus herself.

Appearance
Ridley's appearance has undergone numerous changes. In the original game, he was a purple dragon as tall as Samus, but the first game's canon has been replaced by Metroid: Zero Mission, in which he is his normal size. In Super Metroid, Metroid Fusion, and Metroid: Zero Mission, Ridley is a dragon roughly twice Samus's height, with rather small wings on his back. In Metroid Prime and Metroid Prime 3: Corruption, Ridley is being reformed after his defeat in the first game. He is encased in a black metal suit, and is known as Meta Ridley.

History
Ridley was the one responsible for killing Samus's parents on K-2L. Samus later killed him on Zebes. He was rebuilt cybernetically by the Space Pirates during Metroid Prime, but was again defeated by Samus on Tallon IV. Ridley will appear in Metroid Prime 3, but his role is unknown. In Super Metroid, Ridley attacks Samus on Zebes again, but is defeated once more. His body is aboard the BSL station in Metroid Fusion, where it gets infected by an X Parasite and fights Samus. Why his body was aboard a Galactic Federation station is unknown.

Weapons
Ridley can shoot fireballs from his mouth and pick up Samus, crunching her in his hands. He can also swipe at her with his claws. In Metroid Prime and Metroid Prime 3, he can fire lasers from his mouth as well.
