Annis hags are among the most fearsome and gruesome of their kind, often considered the most horrible of hags. Standing at an imposing height of 8 feet and weighing around 325 pounds, an Annis appears as an ancient, impossibly tall female human with deep blue skin and filthy black hair. Their appearance is both terrifying and formidable.

These hags are known for their physical prowess and their love for disguise, often using their ability to transform into exceptionally tall humans, fair giants, or ogres to deceive their prey. They prefer to divide and confuse their foes before striking, using their claws and bite in combat. Annis hags are equipped with spell-like abilities, such as disguise self and fog cloud, to enhance their deceptive tactics.
