Tyr
Tyr (Old Norse: Týr) is the god of law and retribution in Norse mythology; he was also associated with war and heroic glory. He is a member of the Æsir. He is the son of either Odin or the jötunn Hymir. One notable feature of Tyr is that he has only one hand. Tyr was known in Gothic as Teiws, in Old English as Tīw, and in Old High German as Zīo, all of which stem from the Proto-Germanic name *Tīwaz. The English weekday Tuesday bears his name (from Old English Tiwesdæg - “Tiw’s Day”).
How Tyr lost his hand
At one point in time, the gods decided that the wolf Fenrir (also called Fenriswolf) could no longer go free. They wanted to lock him up onto a chain. But he broke every chain they tried to put on him. Finally, they had the dwarves make a magical chain. But Fenrir sensed what the gods would do. So Fenrir asked that one of them put his hand into his mouth. Knowing that if Fenrir was left unfettered, he would have grown strong enough to kill all the God's and destroy the world. Tyr was the only one who had the courage. When Fenrir sensed he had been tricked, he bit off Tyr's hand. Tyr remained handless forever.
Fenrir will remain bound until Ragnarök. Then, Tyr's opponent will be Garm, the guard dog of Hel.
