15 Fantastic Four Villains Who Could Be The Next Big Bad Of The MCU
3. Mephisto
Like many major characters in the Marvel Universe, Mephisto became an adversary or ally to countless heroes and villains. Debuting in The Silver Surfer #3, he's crossed paths with everyone from Spider-Man and Daredevil to Ghost Rider and Thor.
Regarding the Fantastic Four, Mephisto has tried to capture and torment their souls, including Franklin Richards. In one event, he imprisons the soul of Doctor Doom's mother. Although he's often overcome, his immortality prevents him from ever being truly defeated.
While some may not consider Mephisto a notable Fantastic Four villain, this character is an ideal big bad for the MCU, especially given his history with remaining heroes. He plays a role in the creation of Scarlet Witch and Vision's children which allows him to easily move into WandaVision.
With rumors that Ghost Rider will return to the silver screen in Doctor Strange in the Multiverse of Madness, the table is set for Mephisto to weave his way into the MCU with help from the Sorcerer Supreme and Scarlet Witch. We've seen how the Avengers face a threat from space - how would they counter a demonic invasion from hell?
