Loki is a happy and curious child who is kind to others when he engages in conversation with them, believing that he should help people whether they be living or dead. He is fond of exploring and learning Norse mythology, particularly from Mimir and Freya. Throughout his childhood, he has made great strides in controlling his temper and no longer lashes out as he did before. He sometimes charges recklessly into battle without hesitation. Despite learning about his godhood, he still retains his childlike qualities. Loki has also become more independent and is obsessed with figuring out who he is as an individual outside of his father, and expresses a lot of confusion and uncertainty on the matter.

Loki, referred to as Atreus in some Greek tales, is the Norse God of Mischief and the Champion of the Jötnar. Introduced as the son of the "Marked Warrior" and Faye, Loki joined his father on a journey millennia ago to spread his deceased mother's ashes on top of the highest peak in all the Nine Realms. On their journey, his father taught him how to survive and fight as a warrior while he taught his father to open up to those that can help them. During Fimbulwinter, he sought answers about his Jötunn heritage, something his father cannot answer. This makes him secretly partner up with Sindri to reexamine the Jötnar shrines, where they learn that a God of War and Champion will be of great importance during Ragnarök. As his father found out about his secret activities, he reluctantly agrees to help Loki, hoping to prevent Ragnarök. While Ragnarök was prevented, Utgard-Loki previously banished Loki to Jotunheim and took his place to challenge Magnus Chase and his friends.
