Mire Giants are creatures native to Vanaheim.
History[]
Mire Giants were used to drag skiffs through the river. Thor fought against one of them after being stranded on Vanaheim by Loki. He later rode a skiff that was being pulled by a Mire Giant in order to reach Frostgrinder in hopes of returning to Asgard. The Giant was attacked in hopes of stopping Thor, but Thor saved it and rode it to Frostgrinder. As Thor went to Frostgrinder, the Mire Giant got angry and attacked Thor, although Thor defeated it.[1]
