Surtr was the host of the Duel of Legends Cup. He invited the greatest duelists in the world to come to his island Ragnarok, and participate in order to become the king of Duel Monsters. Little is known about him by those he invited, but many are surprised by his Transcenders and the fact they are able to wield cards such as the Earthbound Immortals.
The tournament ends with Surtr's defeat at the hands of the player. He is willing to divulge information about the Transcenders, but Odin quickly silences him and sends everyone to Bifrost, an underground tunnel in Yggdrasil. Here, Odin states Surtr himself is also a Transcender and that he is to follow any and all of Odin's commands. As Surtr denies those claims and refuses to obey Odin after being double-crossed despite assisting him so far, he is dragged down deep beneath Bifrost.
After the player descends to Hlidskjalf and manages to defeat Odin once, Surtr resurfaces and attacks Odin, stating he now understands how a duelist is like while still denying being a Transcender. However, Odin only has his armor damaged and survives the hit, and retaliates by destroying Surtr.
The journal entries that can be found in Niflheimr confirm Odin's claims about Surtr - his body was found inside a coffin in Yggdrasil by a team of scientists, whose leader described him as indistinguishable from a human being. This would make Surtr the perfected Transcender whose creation got Odin's spirit sealed away, as its development was one step of a plan to seize control of the entire world.
