Dark Splinter
From Wikitroid, the Metroid wiki
Dark Splinters were Splinter Darklings that inhabited Dark Aether, although those possessed on Aether roamed there. Dark Splinters look strangely similar to Warrior Ing, and are much stronger than their Aether counterparts. One blast from a Light Beam will destroy them, or two Charge Beams. Also in the game you face a huge Dark Splinter called a Dark Alpha Splinter.
Dark Splinters were the cause of the GFMC Task Force Herakles' demise.
