Funko's line of Thor: Ragnarok Pops may reveal a secret villain not yet seen in the film. As reported by SyFyWire, the GameStop exclusive figure from the wave is Surtur, the evil fire giant who is behind both the mythical Ragnarok and some versions of the comic book Ragnarok, the downfall of Thor and the gods of Asgard.
If Surtur is part of the line due to inclusion in the film, rather than a thematic connection, this would be the first look at something approximating his onscreen appearance.
Meanwhile, Hot Topic's exclusive figure is a bearded Thor (with his long locks as well), holding what appears to be the head of a fire giant - possibly Surtur himself. The figure and packaging give no indication as to any potential story context.
Thor: Ragnarok is due out in theaters November 3, 2017.
