My Space Is Infinite, So Stockpiling a Billion Supplies Makes Perfect Sense

[Space + Stockpiling Supplies + Superpowers + Zombies + Ruthless Protagonist + Building a Faction]

Is the apocalypse cruel? No, I have a super-infinite space.

Is there no food in the apocalypse? No, I've stockpiled a tiny bit of supplies. (A billion tons.)

Is the apocalypse lonely? No, I've bound countless useful people to me.

Warning: No saints allowed!
