Punisher of the dead (Call of Duty zombies x punisher male reader.)

After an event that ravaged the world of a universe of heroes and villains, an anti hero/vigilante saw his world and reality being destroyed. As before his death, a portal opened up to an unknown dimension. To escape the dying realm.

In a world overrun by the undead, Y/N Castle, known as the Punisher, finds himself in the midst of a global zombie outbreak. As he fights to survive, he stumbles upon a group of survivors holed up in a mysterious, long-abandoned research facility. Uniting with this diverse band of fighters, he learns of the facility's dark past and its connection to the origins of the zombie plague.

As the group battles wave after wave of relentless undead, they uncover clues that lead them deeper into the heart of the facility. Along the way, they encounter twisted experiments, uncover the truth about the outbreak, and face off against a powerful, enigmatic enemy who seeks to weaponize the zombie virus for their own nefarious purposes.

With his skills as a battle-hardened vigilante and his unwavering determination to protect the innocent, the Punisher becomes an invaluable asset to the group. Together, they must navigate treacherous traps, solve cryptic puzzles, and confront their own inner demons as they race against time to stop the spread of the virus and prevent a global/universal catastrophe.

As he wouldn't be the only person to be from an alternate reality/world, where there were survivors from other worlds that faced destruction and annihilation. Only fate can determine what happens.
