A hulking, terrifying figure that embodies Hate, Witiko’s form is that of a pegasus skeleton animated by ice, sleet and snow, with a giant rack of antlers. Immense in size, Glados (who, in turn, is half a head taller than Celestia) would barely be able to scrape this monstrosity’s chest with the tip of her horn.
As most ponies would be stricken terrified by her form, as well as minor factors such as giving off a sub-zero aura that can freeze mortals solid when they get too close, and her size being unconductive to fitting inside buildings, Witiko prefers to take the guise of an alicorn when around pleasant company.
