Váli
In Norse mythology, Váli or Boe or Bous (Latin) is a god and the son of the god Odin and Rindr. Váli has numerous brothers including Thor, Baldr, and Víðarr. He was born for the sole purpose of avenging Baldr, and does this by killing Höðr, who was an unwitting participant, and binding Loki with the entrails of his son Narfi. Váli grew to full adulthood within one day of his birth, and slew Höðr before going on to Loki. He is prophesied to survive Ragnarök.
