The Megaroid(メガロイドMegaroido) is a creature created by the Space Pirate leader, Dragüd. He once unknowingly landed on a planet with Metroids and the parasites made quick work of his minions. By studying a dead Metroid he obtained, his scientists had designed a "far more aggressive and submissive... A bioweapon surpassing the Metroids!" Before they could perfect the mind control needed to keep it docile, it broke free of the D-Block of Dragüd's Ship while on planet Liberty, drained two scientists of their life energy, and knocked over three more Pirates while escaping through an opening door.
