Loki is depicted as a trickster that can change his look to meet the needs of whatever he wants.
In Norse mythology, Loki is best known as the trickster god. A lot of the time, he uses his cunning to help the Æsir out of trouble – other times, he’s the reason they’re in trouble in the first place. The Æsir are infuriated by him and dependent on him. He helps the Æsir and marches against them in Ragnarok.
