Like too many catastrophes. The virus came from a world of hope and love. It all started when Hank Pym went to the quantum realm to save Janet. But something wasn't right. She had a virus that corrupted her brain and turned her into a zombie. Soon it became a worldwide pandemic and the Avengers' heroism has sealed humanity's fate because when Earth's mightiest heroes fell, nobody stood a chance.

New York 3:00 P.M.

A man walked through the empty streets. This was one of the most skilled combatants Shang Chi, as he looks around. He sees some zombies eating something. "That seems like overkill." He says. He then sees more zombies and fought back punching and kicking off their heads with ease.

He continues to fight and avoid getting bit while Doctor Strange arrives to help.

"Careful. Don't let them bite you." strange warned.

A zombie gets shot by Kate Bishop while another one gets reduced to a star shaped mess on the pavement by America Chavez and Spider-Man and Ms. Marvel help defeat some Zombies.

"There's too many of them!" Ms. Marvel cried.

Things seemed grim until the heroes retreated into the Sanctum Santorum.
