Týr

This is the Norse god Týr, god of Single Combat, Law and Justice. He lost his hand and arm by sticking them in the mouth of the great wolf Fenrir (long story) but thanks to superior Asgardian Cyber-technology, he's able to fight another day!

Fun fact: That little arrow on his chest? It's a T-rune and is named after Týr, and it's where we get the letter 'T' from. His name is also where we get "Tuesday" ("Tyr's Day" or "Tiw's Day") from!
