Thor had an idyllic childhood, brought up in Asgard as the treasured son of Odin and his wife Frigga. His best friend and playmate was his adopted brother Loki, and though they were rivals for their father's throne, they still remained close companions.
Brought up in the warrior culture of the Asgardians, Thor valued strength, courage, and loyalty above all else. He desired to be exactly like his father the war hero, and often remarks on the monsters he will slay and the wars he will win when he is king.
He proves himself a great warrior, often leading his band of warriors that includes his brother Loki, Lady Sif and the Warriors Three on adventures.
Odin decides to name Thor king and ruler of Asgard as he is about to enter the Odinsleep after putting it off so long. As he is about the name Thor king, he senses that the Frost Giants have snuck into Asgard and into Odin's vault to steal the Casket of Ancient Winters. Odin, Thor and Loki goes into Odin's vault to find the Destoyer slaying the Frost Giants. Thor says that they must go to Jotunheim to teach the Frost Giants a lesson. Odin says that the tresspassers were a few and that they had paid with their lives but Thor says as king of Asgard he will lead an army to Jotunheim to attack the Frost Giants. Odin though cuts him and says that he is not king yet.

In their quarters, Thor begins throwing tables around in anger. Loki manipulates Thor into attacking Jotunheim before Sif and the Warriors Three arrive. Thor then announces that they are going to Jotunheim. They travel to the Bifrost where they seek Heimdall's permission to travel Jotunheim which he granted.
In Jotunheim, Thor leads the warriors to King Laufey's chamber where he warns them to leave whilst he still allows them. One Frost Giant approaches Thor before Loki leads him away until the Frost Giant calls Thor a princess. Thor unleashes his anger and the mighty power of Mjolnir and the warriors bravely battle the Frost Giants. Fandral is struck by a Frost Giant and warn Thor to pull back. Thor tells them to get out of there whilst he battles the Frost Giants.
As his friends leave and reach the Bifrost Bridge, Thor unleashes the full power of Mjolnir and erupts the ground around him killing hundreds of Giants, before flying at full speed to kill Laufey's beast that was chasing the Asgardians. Laufey and his whole army then surround Thor who are at the edge of a cliff. Before they attack, Odin arrives and warns Laufey telling him to preserve the peace and not respond to the actions of a boy. Laufey says that war has begun so Odin transports he and the other Asgardians back to Asgard.
