Super heroes still gotta eat, right?
Tough chick vampire hunters in the big city gotta get the talcum powder to make sure their leather pants don’t stick to them from somewhere.
Ancient Greek deities reborn in human form (whether aware of it or not) probably don’t get their milk from women turned into cows by Zeus trying to disguise them from Hera. And if they did it probably would be hella weird.
Sexy modern fey here to tempt mortal men into illicit relations need to buy lots of nappies for the resulting offspring, and lets face it, cloth is better for the environment, but who’s got the time around all that seduction?
And where do they go to buy all this? The supermarket.
Take a modern fantasy character, and make them do the grocery shopping. But let’s not just have them go and get some ramen-in-a-cup, make something happen. Maybe a mist filled with eldritch terrors rolls in, confining them to the store with other survivors (or not, Stephen King already did that). Maybe the last box of Fruit Loops has another hand on it – and that hand belongs to their nemesis.
How much fun can you have at the grocery store?
