A new piece of fan art casts one of WandaVision's stars in a more devilish light.Artist Raf Grassetti recently posted his take on the Marvel Cinematic Universe's version of Mephisto on Twitter, using actor Evan Peters as inspiration. Grasetti's design gives Evans the signature spiked hair and red skin of the demonic overlord, with a organic sort of armor.RELATED: WandaVision Theory: Why Pietro Is DEFINITELY an Imposter

Peters first appeared on WandaVision during the fifth episode, titled "On A Very Special Episode..." There, he reprised his role as Wanda Maximoff's super-speedster brother Pietro -- better known as Quicksilver. Peters previously portrayed a different version of Quicksilver in 20th Century Fox's X-Men film franchise prior to the studio's acquisition by Disney; fans have speculated on whether this Pietro comes from an alternate universe or is really Mephisto in disguise, given a pair of comments he made in the latest episode "All-New Halloween Spooktacular!"

Grassetti is best known as the art director for the God Of War video game series. He has posted other works of fan art on social media based on franchises including Teenage Mutant Ninja Turtles and Star Wars.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau and Kathryn Hahn as Agnes. New episodes air Fridays on Disney+.
