What is the name of the antagonist in Metroid Dread?

The antagonist in Metroid Dread is Raven Beak. He is the leader of the Mawkin, a militaristic Chozo tribe, and the central villain behind the crisis on the planet ZDR.

Raven Beak wants to exploit Metroid DNA to create a powerful army and conquer the galaxy. He previously helped contain the Metroids on SR388, but turned against the scientific Thoha tribe when they planned to destroy the species. He murdered nearly all of them, sparing Quiet Robe because Thoha DNA could control Metroids.

Raven Beak manipulates the Galactic Federation into sending E.M.M.I. robots to ZDR, intending to use them to extract the Metroid DNA inside Samus. He also disguises himself as the computer voice ADAM while guiding her through the planet. This deception is why some players initially mistake ADAM for the game's main threat.

Kraid, Ridley, and Mother Brain are important Metroid villains, but none is the principal antagonist of Dread. Raven Beak is ultimately revealed as the mastermind and final boss.
