1. Jack Harper (Oblivion)
Can't complain living through the apocalypse flying around the desolate landscapes in the Bubble-ship. And also the likeliness of stumbling upon some amazing hidden spots and setting up shop, starting over again.
2. Luke Hobbs (Fast & Furious 6)
You'd need a driver, someone good with a gun and someone not to be messed with. Who better than Hobbs, any apocalypse baddies come our way he'll spit out some badass one liners before taking them out. Safety comes first in the name of Hobbs.
3. The Doof Warrior (Mad Max Fury Road)
The wasteland must be a pretty depressing place, I'd miss music so having this guy perform whilst attached to a bungee chord on a giant speaker system is a no-brainer, you could have yourself your very own end of the world party.
With these three in tow I reckon the apocalypse would be rather smooth sailing.
