Dark Shredder

From Wikitroid, the Metroid wiki

Dark Shredders, Dark Aether counterparts of the Shredders, are enemies that appear in Samus Aran's fight with the Chykka, and are mainly there for powerups, like energy and ammo. Like their Aether counterparts, Dark Shredders come out of water when agitated and attack by exploding near their enemy.
