Don't forget Inhumanoids.
Giant monsters that live in the center of the earth that rise up to kill and destroy.
Metlar: reached down his own throat into his gut to retrieve balls of lava to throw at his enemys.
Tendril: tentacled green thing, when parts were cut off they would grow into a whole new Tendril monster
Decompose: giant rotting beaked skeletion thing. anything he touched mutated into a hideous deformed zombie version of itself. and he would capture people by sticking them behind his own ribcage.
that's fuckin' saturday morning!
