Magmoor

Magmoor are creatures found on Tallon IV that inhabit areas of extreme heat, specifically, certain areas of the Magmoor Caverns, which are named after them. Magmoor are predatory creatures. They hide and wait under Lava, and only become detectable when they rise out to attack their prey with powerful blasts of fire. Though intimidating, they are actually very easy to defeat, as a charged blast or missile stops them from attacking. If frozen by a uncharged Ice Beam shot, only the head will be frozen. If a charged ice beam is than fired at him the ice will get thicker. Even though they live in extremely hot environments, Magmoors are vulnerable to the Plasma Beam.

Humourously, Samus can fire a Missile to release a large stalactite from the ceiling and it may fall on a Magmoor which often emerge under one, killing it instantly.
