Based on the fire giant Surtr from Norse mythology, he was adapted by writer Stan Lee and artist Jack Kirby, and first appeared in Journey into Mystery #97 (October 1963).

Surtur made his live-action debut in the Marvel Cinematic Universe film Thor: Ragnarok (2017), motion-captured by Taika Waititi,[3] and voiced by Clancy Brown.

Based on the fire giant Surtr from Norse mythology and created by Stan Lee and Jack Kirby, the character first appeared in Journey into Mystery #97 (October 1963).

Together with the Storm Giant Skagg, the character invades Earth, although the pair are met by Odin, his son the Thunder God Thor and fellow Asgardian Balder.

[9] In the title Thor the seer Volla predicts that Loki will free Surtur and other enemies of Asgard and eventually bring about Ragnarok – a war that will end with the destruction of all the Norse Gods.

[12] Surtur reappears wielding the huge magical blade Twilight, and after sending a horde of demons to invade Earth storms Asgard.

[16] Thor returns from a period of self-induced hibernation in a third self-titled volume, and enters the Odinsleep to find Odin in a limbo dimension between life and death, where Surtur stored a portion of his essence to prevent himself from being killed forever.

[18] He then set the world tree Yggdrasil on fire and attempted to turn the Vanir gods against the Aesir in preparation for his assault on Asgard.

Standing over 1,000 feet (300 m) in height, Surtur possesses physical attributes far surpassing Thor himself, the ability to generate intense heat, flames, or concussive force, a prehensile tail, capable of transforming his fingers into serpents via molecular rearrangement, flight, and interdimensional travel.

This giant weapon possesses mystical properties that allows Surtur to manipulate magical energy in vast amounts and perform nearly limitless feats, such as shattering dimensional barriers or inhibiting Odin's powers.
