Isohgin

Isohgin is one of the "nightmare-duo" from Eternal that are said to be the best hunters there. He is the tall one of the two and mostly just repeats what Yadokhan says. Together, the two of them transform into a sea anemone on a hermit crab with Isohgin being the sea anemone on the top. His last episode was episode 38 along with his partner.
