WARNING: This article contains potential major spoilers for Marvel's Thor: Ragnarok, arriving in theaters Nov. 3.

By now, fans are accustomed to pivotal scenes and surprise characters from superhero films being revealed months before the release through merchandising tie-ins. (Remember the Captain America: Civil War LEGO set with "Giant-Man"?) So, why should Thor: Ragnarok be any different?

Although the enormous fiery demon Surtur has been long rumored -- and even expected -- to appear in the Marvel Studios sequel, the first confirmation arrives in a wave of newly announced toys from Funko.

A flaming Surtur, grasping his enormous sword Twilight (aka the Sword of Doom), appears as both a Mystery Mini and a Pop! Vinyl figure. Fenris Wolf, whose involvement in Ragnarok shouldn't be surprising either, is also depicted in Mini form.

Based on the fire giant from Norse mythology, Surtur was introduced into Marvel Comics lore in 1963 as a native of Muspelheim who's merely biding his time to destroy both the gods and humanity. Like his mythological counterpart, Marvel's Surtur plays a key role in the events of Ragnarok, known as "the destruction of the gods" or "the twilight of the gods."

Surtur has been a recurring foe of Thor throughout the decades, and has crossed over into animation on several occasions -- from Spider-Man and His Amazing Friends to Hulk Vs Thor -- as well as into video games.

Directed by Taika Waititi, Thor: Ragnarok stars Chris Hemsworth as Thor, Tom Hiddleston as Loki, Cate Blanchett as Hela, Idris Elba as Heimdall, Jeff Goldblum as Grandmaster, Tessa Thompson as Valkyrie, Karl Urban as Skurge, Mark Ruffalo as Bruce Banner/the Hulk and Anthony Hopkins as Odin.
