Super-Soldier experiments that went horrifically wrong.

Dr. Theodore "Ted" Sallis injected himself with Super-Soldier serum to prevent it from falling into the wrong hands. The serum left Sallis vulnerable to mystical energies that swept through the Florida Everglades, and he was transformed into a whole new life form, a being who retains only a semblance of humanity. The Man-Thing became the guardian of the Nexus of All Realities, a breach in the fabric of spacetime binding all dimensions together. The creature has already been confirmed to exist in the MCU, with Thor: Ragnarok showing its distinctive visage on the side of the Sakaaran Palace. This confirmed the Man-Thing had been one of the Grandmaster's past champions; given the Man-Thing had clearly traveled through a portal from Earth, the Easter egg may also have confirmed the existence of the MCU's Nexus of All Realities.

The Werewolf by Night trailer features a Man-Thing first look, showing a remarkably comic-book-accurate interpretation of the creature. The Man-Thing's most distinctive power is also shown, as it uses a "burning touch" upon one of the monster hunters; anything that feels fear burns at the touch of the Man-Thing. It's unclear whether the Man-Thing will play a major role in the Disney+ special or whether it will instead simply make a cameo, but the brief glimpse in the trailer nonetheless sets up a figure who could be key to the Multiverse Saga. As the guardian of the Nexus of All Realities, the Man-Thing would potentially be a force to be reckoned with in the coming multiverse war.

Man-Thing Suggests Werewolf By Night Is A Major MCU Addition

Werewolf By Night Man-Thing

There had been initial speculation Werewolf by Night was not really canon to the MCU; after all, the Disney+ special wasn't d on the initial Kang the Conqueror and his multiversal war.

Werewolf by Night is unlikely to present the Man-Thing's origin simply because the creature has already existed in the MCU for years. Still, assuming the Man-Thing's story parallels that of the comics, this creature is the result of another wave of Super-Soldier experiments - comparable to those that created Isaiah Bradley or the Hulk. The novelization of The Incredible Hulk even hinted Thunderbolt Ross had been involved in other failed Super-Soldier projects, meaning the comparison between the Man-Thing and the Hulk may well be an entirely appropriate one. It will be thrilling to see more of this creature in Werewolf by Night.
