Erik Hellstrom, also known as Odin, is the third antagonist of Disney's 2003 direct-to-DVD film Atlantis: Milo's Return. He was one of Whitmore's competitors.
He was voiced by the late William Morgan Sheppard.
Erik Hellstrom used to be a well known businessman and rival to Preston T. Whitmore. After the stock market crash destroyed his company, he went insane, believing himself to be the Norse god Odin.
One night, he went into Whitmore's manor and stole one of his possessions, an ancient spear called the Gungnir, presumably an artifact of Atlantean origin. When Milo and his friends track him down in the frigid Nordic Mountains, he presumes Kida to be his long-lost daughter and kidnaps her.
His intentions are to end the world in Ragnarok. He creates a lava beast (Surtur) and then an ice beast to destroy the world, but well-placed explosives used by Vinny to distract the monsters long enough for Kida to retrieve the spear and vanquish the beasts by crushing them with Hellstrom's castle, Asgard.
After the castle's destruction, Hellstrom mourns for his lost castle before he is presumably taken to a mental hospital.
