Valhallen is a member of the Justice Friends segment on the Cartoon Cartoon Show, Dexter's Laboratory. He is a parody of the Marvel superhero, Thor with the personality of real-life guitarist, Eddie Van Hallen.
He is the Viking God of Rock and has the personality of a laid back rocker. Although he doesn't look or seem the type, Valhallen is a wise man (likely due to him being a god) and shows much more common sense than Major Glory or the Infraggable Krunk. Due to his rocker status and good looks, he is able to woo tons of girls. His Golden Axe (what he calls his guitar) is the source of his godly powers and being separated form it is his only major weakness. Without his magic, he is reduced to a stereotypical nerd.
