Reginald Fortean’s Abomination
This MCU villain might be too terrifying to show on screen. The story behind this guy includes Fortean, who took Gamma-Activated Tissue from the corpse of the original Abomination. Then, when he made contact with it, he was encased in an Abomination-like shell. He has an eight-fingered hand crown that sits on top of his head. Now, he has superhuman strength, enough to match the strength of the Hulk. Additionally, he can regenerate from grievous injuries like lost organs, has a claw on every single one of his fingers, and can generate a corrosive acid that can dissolve the flesh of the Hulk (Screen Rant).
