Magnus and his friends encountered Harald at the pier and requested that he take them fishing. After being paid in Red Gold by Sam, Harald allowed her and Magnus to come but not Hearth and Blitz. They set sail to Jotunheim and threw in the bait. Before long they got a bite. Harald pleaded with Sam and Magnus to cut the line but they did not. Jormungand then surfaced and then Ran appeared soon after. After the demigods retrieved the sword Harald set sail for shore. Sam made sure he left them in Midgard rather than Jotunheim.
- Cryokinesis: As a frost giant, Harold has some control over the cold.
- In Norse mythology, Thor went on a fishing trip with a giant named Hymir. The part where Magnus goes fishing is similar to Thor's experience, Harald plays the role of Hymir.
