Fomorian

Fomorian Giants or Fomorians are large humanoid creatures within the world of Critical Role and Dungeons and Dragons.

Creature Information
Fomorians resemble humans with purple blackish skin and bright yellow eyes, one larger than the other. Physically they appear to be somewhat impaired, usually having a very curved spine. They can be as tall as 20 feet, and have an average level of intelligence. They are very aggressive, and are considered evil. They reside in the Underdark.

Vox Machina accidentally got into a fight with a Fomorian Giant when looking for a place to set up camp on the island Yug'Voril was located on in preparation for facing K'Varn. Scanlan was able to gain control of the giant, and the group later dropped the creature on top of the structure K'Varn was using to control the Illithid colony.
