Maguma's name literally means "magma", which could be a reference to how Maguma is weak to high temperatures.
Maguma looks like a giant brown walrus with yellow eyes, pale tusks, smooth skin, and no visible hair. Maguma also lacks a tail.
Maguma first appeared when it was awakened by missile fire at the North Pole. Maguma attacked the base and it went home to its valley. A VTOL aircraft was sent to kill Maguma, and it buried it under a pile of rocks. Maguma broke out of the rocks and attacked again. The aircraft attacked Maguma with energy beams, killing it.
Maguma's roar was an elephant trumpeting sound, but was deepened and slowed down. Maguma's roar was later used for the
Ultraman 80 , kaiju Salamandora.
