Collects Thor & Loki: Double Trouble (2021) #1-4. They're brothers, gods and sons of Odin - but Thor and Loki just don't get along! Especially since Loki keeps tricking Thor into doing things that will get him in trouble. Even so, when Loki dares Thor to steal a powerful relic from Odin's vault, how can the God of Thunder say nay? As Loki summons a serpent set on city-smashing, Thor has to clean up his mess...again! But when the feuding siblings are transported to an alternate universe, they meet a very different Thor: Jane Foster! Can the Goddess of Thunder help these misbehaving brothers find their way home? Mariko Tamaki and Gurihiru - the fan-favorite team that brought you SPIDER-MAN & VENOM: DOUBLE TROUBLE - return to unleash anarchy in Asgard!
