What Happens in the Ironheart Finale with Mephisto?

Mephisto makes his MCU debut in the Ironheart series finale, portrayed by Sacha Baron Cohen. He is revealed to have granted Parker Robbins (The Hood) his powers—his cape infused with dark magic that slowly corrupts him. Additionally, Mephisto tempts Riri Williams with a Faustian offer: restore her friend Natalie in bodily form instead of artificial intelligence.
Mephisto’s arrival broadens the MCU’s narrative into the supernatural realm. Known for power-swapping deals in the comics, his presence connects to mystical threads from WandaVision, Doctor Strange, and upcoming plots involving characters like Wanda Maximoff and the Fantastic Four. This sets up potential story arcs in Phase 6, including Avengers: Doomsday, Doctor Strange 3, and Spider-Man: Brand New Day.
