i hate zombies and i wish this stupid fad would die. they're even worse than all this My Little Pony guff.
If it died, it would just come back from the dead. You know how it goes. Anyhoo you need to watch the Zack Snyder Dawn of the Dead remake.
While the gears in my head are going...
An alternate reality line of post-apocalyptic Joes would be amazing. Though probably too gritty for the kiddos. Maybe a couple 7-packs, a comic mini-series (4-6 issues) and that's it.
It worked for the X-Men and Age of Apocalypse.
Instead of having a Joe 7-pack and a Cobra 7-pack, have a Survivors 7-pack of assorted Joes/Cobras. Plus just for kicks, stuff the survivor pack with fan favourite b-squad guys like Doc, Shipwreck and maybe just one of the Crimson Twins and then do up the a-listers (and the other Crimson Twin) as zombies/mutants.
