Ymir is a Marvel Comics character that appeared in The Avengers: Earth's Mightiest Heroes, Hulk and the Agents of S.M.A.S.H., Ultimate Spider-Man, and Marvel Super Hero Adventures: Frost Fight. He is awakened from his ice volcano prison on Earth by Laufey as part of the Frost Giants' plot to bring an endless winter to Earth. Ymir then attacks Thor and the Hulks as they work to defeat Ymir. When Skaar tried to repeatedly stab Ymir, he froze Skaar who was caught by A-Bomb before he can hit the ground. Thor tells Hulk that they will have to find Ymir's weak spot. Skaar's sword was left in Ymir as the Hulk's act as they attack the weak spot. Before Ymir can hit A-Bomb, She-Hulk gets both of them out of the way. Thor comes up with a plan where he and Hulk attack Red Hulk enough to heat him up and throws him towards Ymir which cracks up Ymir. Thor then fires his lightning which shatters Ymir as Laufey retreats back to Jotunheim. Later, Ymir collaborates with Loki to steal the powers of Santa Claus.
