Odin Borson

Odin is the ruler of Asgard and the father of Thor and Loki. He is responsible for Loki's imprisonment and has confined his rebellious son through magical means. Loki's escape occurs due to years of effort involving Heimdall and an errand leaf of his capture tree. Ultimately, allowing Loki to leave Asgard and carry his conflict with Thor to Earth.

Once Thor defeats Loki on Earth, he returns his brother to Asgard rather than simply leaving him defeated. Twice over, Loki escapes Odin's watch to be returned by his son Thor.

After Loki's escape and Thor's return of his wayward brother, Odin orders Loki to stay put. Naturally, Loki ignores the order and follows Thor back to Midgard.

When Thor is overwhelmed by Sandu and trapped beneath a building, Thor calls upon Odin for assistance. Odin responds by sending the Valkyries to deliver his Belt of Strength to Thor. The belt gives Thor the additional strength needed to escape Sandu's trap and continue the fight.
