Okay no seriously someone from hell has summoned them to try and take over wwe. So the wrestlers are fighting back. Just like any zombie movie it's usually a regular guy fighting back e.g Ash in evil dead. At least these have fighting experience. Plus the character of the undertaker is in fact a Zombie of sorts himself so from kayfabe it makes sense with his character.
After the epic, epoch-spanning first issue, there was only one place for our eternal champions to end up – Wrestlemania! What will the stars of the WWE do when mystical terrorists grab the ringside seats? Will Triple H, John Cena and the Undertaker be able to stop heavily-armed, mysterious bad guys? And how do these unforgettable events tie into the centuries-old face-off between the Shadow King and the King of Kings?
And so, as Ellis' Stormwatch launched the last great revolution in superhero comic books, so does WWE Heroes launch a bold new epoch in sequential graphic storytelling!
Edit: That shot of John Cena is the most hilarious thing I've seen in a while.
