The Zombie Apocalypse

Y/n, Echo(my oc), Carl, Shiro, Katie(also my oc), Pidge, Hunk, Allura, Keith, Lance, Rick, Judith, and Coran are in a zombie apocalypse but what will happen in the in the apocalypse? An explosion happened that made the apocalypse had started. What will happen to every one in this?

I made a mash up with Voltron and The Walking Dead so Yay! I'm a fan of both so I had to do this. I also don't own The walking dead and voltron. They go to the owners.
