Fire Entity

A mysterious creature made of pure Fire, a Fire Entity attacked Toa Metru Vakama while he was searching one of the Makuta of Metru Nui's lairs for boat materials. It was defeated when Vakama absorbed all of its heat and froze it. Vakama himself was left unconscious, and by the time he awoke, the creature was gone.

This creature was not only able to control heat and flame, it was heat and flame. It had the abilities to levitate on updrafts of hot air, throw fire balls, and unleash massive amounts of heat without rest. It did not appear to be capable of speech. If it was, it never demonstrated it.
