Bishop

Bishop is introduced in chapter 7 of Metroid EX as Greed's general of knowledge. Calling himself "beguiling", Bishop is a robed figure with bull horns, an eye-like mouth in his forehead (and two eyes without pupils) and shoulderpads. He is summoned by Greed and tasked with going to the graveyard planet to await Samus Aran. Bishop reports the insignificant news of the Deadly Six Stars' complete annihilation, and Samus' recovery of five out of seven Data Capsules containing her stolen abilities.

Samus lands on the graveyard planet and encounters the Stars returned as zombies. Bishop explains that the planet is populated with the spirits of those Samus has defeated, all of whom seek vengeance. The Stars, which combine into one massive zombie, are destroyed by Knight, which reveals that they are actually robotic replicas of the Stars. Bishop is last seen expressing his anger towards Knight for interfering with his plan.

Trivia

 * The names of Bishop and Knight refer to pieces in a game of chess.
 * Bishop is also the name of a crucial character in Aliens, a film which heavily inspired Metroid II: Return of Samus.
