A squad of vampires attack the Avengers at the Avengers Tower and are defeated, with the Avengers capturing their leader – who turns out to be a Black vampire Widow. Through her, the Avengers are offered a deal from Dracula, King of the Vampires, that he will only trade the Black Widow for Captain America. The Black Widow had traced the Red Skull to Transylvania, captured and turned by Dracula. Captain America tells the Avengers that the only way to save her is to destroy the vampire who bit her. Iron Man starts a scientific analysis of the Black Widow of finding a cure for her condition.

( I will try ad Dalinda later.)

On the way to Transylvania, Captain America loads silver-plated strike discs into his belt pouches while recounting that Dracula was an uneasy ally of the Allies in World War II, as the Allies helped him keep Transylvania free from the Nazi oppression. The Avengers land outside Dracula's castle, which is under a spell that makes it always night. They fight vampires and Dracula, and then split into three groups Thor and Hulk guard the entrance, Iron Man continues to try and find a cure, and the rest enter Dracula's Castle to rescue the Black Widow.

Dracula captures Hawkeye and Falcon and uses them to force Captain America's surrender. Dracula reveals that Red Skull has told him that Captain America's blood, with the Super-Soldier Formula, will make him immune to sunlight. Before he can harm Captain America, other Avengers attack. Dracula bites the Hulk. He becomes a minion vampire under Dracula's control, and Dracula becomes Hulk-like. Ordering the Hulk to destroy the Avengers, Dracula grabs Captain America once more, but the gamma-irradiated blood from the Hulk incapacitates him.

Gamma-irradiated blood affects Dracula, similar to sunlight. Iron Man postulates that if they make the Hulk angry enough, his gamma-blood will rid him of the vampiric infestation. The Avengers attack the vampire Hulk, burning out the vampire blood elements. Dracula, weakened, escapes healing from Hulk's blood's damage to him. Castle is destroyed, and the Avengers fly off in the Aven-Jet Prime.

Iron Man uses gamma-irradiated blood to help cure the Black Widow, who remembers nothing after being bitten by Dracula. "You're fine, Nat?" Deadline says as she places a hand on the black window. Nat nods.
