The question is pretty simple, what or who would you write about if you worked at Marvel? If you want to you can specify if it's an ongoing, a mini-series, or even a one-shot, you could even state who you would want doing the art of it.
I'll start this off with my ongoing idea, All-new Marvel Zombies. My idea is that it would start out as the mysterious outbreak occurs in an alternate universe just as it did in the original mini-series, what's different this time is that a second flash of light occurs and a group of heroes appear to exterminate the undead. After fully eradicating them the group disappears into a place outside the multiverse where their mysterious leader reveals the teams mission to the readers, that thanks to events of the last couple of Marvel Zombies mini-series the undead infestation has begun to infect the multiverse and it's up to them to contain it. It's almost like the Exiles. I honestly hope it would lead to an event where they have to help save the main universe from the zombies.
