The Marvel version of Thor first appeared in Journey into Mystery #83 (Aug. 1962) which was created by Stan Lee, written by Larry Lieber, and drawn by the legendary Jack Kirby.

Australian actor Chris Hemsworth is perhaps best known for portraying Thor in the Marvel Cinematic Universe, including the films Thor, The Avengers, Thor: The Dark World, Avengers: Age of Ultron, Thor: Ragnarok, and Avengers: Infinity War.

Balder, the god of light, is one of Thor's closest childhood friends. It is later revealed that he is actually the son of Odin and Frigga, making him Thor's half-brother. (Loki was adopted!)

Although she has battled alongside Balder, who has developed an unrequited attraction to her, Sif has never shown affection for anyone but Thor and certain individuals who have proved worthy to wield his hammer, such as the noble alien warrior Beta Ray Bill and the mortal Eric Masterson.

A mystical wolf-like creature of the Asgardian dimension Niffelheim, the Fenris Wolf was a child of the trickster Loki and the giantess Angrboda.

Standing over 1,000 feet tall, Ymir is one of the few beings whose power makes him capable of battling Odin to a standstill. The character can generate intense, deadly cold and regenerate from as little as a particle of ice.

The Warriors Three is a group of Asgardian adventurers that are among Thor's closest comrades. The group consists of Fandral the Dashing, Hogun the Grim, and Volstagg the Valiant. Balder is not a member of this group, though he is also one of Thor's staunchest allies.

Once a year Odin must undertake the Odinsleep to regain his strength. During this time Asgard is vulnerable to attack from its many enemies, most notably Odin's adopted son, Loki.

Although not technically a part of the Asgardian dimension, Midgard is considered one of the Nine Worlds because of its significant connections to Asgard.

Huginn and Muninn are Odin's pet ravens. They guided Thor to find the means to end the Ragnarök cycle and again through Hel to find Odin.
