Thor was a poor Asgard villager who stole riches from the wealthy and gave it to the poor. At some point, though, he was severely injured by the Valhalla Palace guardians when he tried to hunt near the Palace. Almost dying, he is forgiven and healed by Odin’s priestess Polaris Hilda, despite his harsh words about her reign. Ever since he felt her pure and warm Cosmo, and was moved by Hilda’s frustration about not being able to help everyone in Asgard despite being Odin’s priestess, Thor swore to protect her as her guardian.
Despite noticing that Hilda’s Cosmo had changed, he fought against Athena’s Saints hoping that she would return to being the kind person she once was. He even threw one of his hand axes against Saori, and when she returned it to him with her Cosmo, he praised her strength. Finally, he asked Seiya to rescue Hilda after being defeated. His armor resemblesJörmungandr, the sea serpent, who faced the Norse god Thor at the Battle of Ragnarök.
