Mimas

Mimas the giant son of Gaea, born to oppose Hephaestus. Mimas was defeated in the first Gigantomachy after Hephaestus dumped a volley of molten iron onto him.

Appearance
Mimas is a 25-feet tall giant (comparatively short), with his skin and dragon-scale legs as black as charcoal. His long oil-black hair is glittered with copper wires and smashed circuit boards. He wears coal-black (possibly Stygian Iron) armor, and carries a massive sledgehammer in his hands.

Abilities

 * Prowess in Battle: In spite of being short for a Giant, Mimas is shown to be a very powerful warrior, since he was able to fight Hephaestus himself in the first Gigantomachy, and only lost after Ares began fighting him as well. In The Blood of Olympus, Mimas was able to battle Piper and Annabeth at the same time.
 * Disruption: as the bane of Hephaestus, Mimas claims that nothing goes right in his presence - maps are misread, devices break, data is lost, and "the finest minds turn to mush." Hence, attacking him with a plan of attack will never work.
 * Giant Immortality: As a Gigantes, Mimas can only be killed by a god and demigod working together, and when he is harmed by anybody else, he heals at an accelerated rate.250px-Sadness_gaia.jpg
