Demagihr possessed two remarkable abilities that made him a formidable foe. One was his capacity to create spatial rifts, allowing him to move in and out of his surroundings and reappear elsewhere. The other was a fusing gas that merged objects together. During the Creation War, a team of Covenant heroes encountered Demagihr, separated from his main forces, in a trap set by the cunning adversary. The Covenant soldiers were saved when Demagihr's gas merged three of them into a single entity, granting them the power to defeat their opponent.
