Magmouth

Bio: The Alien crystal activity has brought about violent disturbances deep within Earth's core. The resulting volcanic upheaval awakens an ancient, fiery elemental formed from molten rock.

Special abilities: Like a walking volcano, this brimstone beast fires red-hot magma from its gaping maw and can set foes ablaze.

Design Process: "Magmouth" was a combination of two separate concepts. The first was a rocky, craggy creature that was basically solid rock. The second was more akin to flowing magma.
