I named mine Odin
It is quite fitting for the little guy! Other good names are Osiris (egyptian, not viking, but still a very cool name. God of the afterlife). Some good viking names: Asmund (divine protection), Brynjar (warrior in armor), Destin (determined), Dustin (Thor's stone), Eirik (King forever), Gandalf (an elf with a wand), Gustav or Gustavo (staff of the Gods), Haldor (the rock of Thor), Jari (helmeted soldier), Jarl (noblemen), Kensley (from a clearing with a spring), Loki (the Trickster), Odin (Fury), Ralf, Ralph Raoul and Raul (as wise as a wolf), Ronald and Ronaldo (wise ruler), Sven and Svend (boy), Tait (cheerful or happy), Tarben (bear of Thor), Thor (God of Thunder), Vali (powerful, strong), Vernon or Vern (of the alder tree), Vidar (fighter in the woods), Viggo (Battle). I hope this helps
Keep us posted on what you name him, he is a cutie!
