According to Marvel Studios' Senior Illustrator Jackson Sze, Surtur could have looked a whole lot different in Thor: Ragnarok.
Sze's concept art for the film shows a Surtur that is decked in metal armor that the artist hoped would be true to his nature as a fire demon. In the piece, the character's prominent horned helmet has shifted up to the top of his head, echoing Marvel's established Asgardian aesthetic more clearly.

An early take on Surtur. I thought I could bring the fire demon aesthetic closer to Thor's world by designing him with twisted and forged metal works reminiscent of fantasy armors. - - - Final Surtur design for the film was done by @aleksibriclot - - - - #thorragnarok #surtur #marvelstudios #marvelcinematicuniverse #fire #armor #demon #conceptart #characterdesign #digitalart #digitalpainting #illustration #conceptdesign
"I thought I could bring the fire demon aesthetic closer to Thor's world by designing him with twisted and forged metal works reminiscent of fantasy armors," Sze explained on post. Marvel ultimately decided to go with a more traditional depiction of the villain. Sze credits Surtur's final design to artist Aleksi Briclot.
