Welcome To Built In A Cave With A Box Of Prompts!

This blog will host the Marvel Cinematic Universe prompts I have come up with/been given by others over the years that I want to see find a good home. The blog's focus is primarily on the movies over the TV shows, though there may be some prompts from Agents of S.H.I.E.L.D. from time to time, as i was active in that part of the fandom before it went AU.

There are all sorts of shippy and gen prompts that I am in the process of collecting and will queue to be posted. While some prompts are too specific to swap out characters/ships, you may edit these prompts as you like...they're mostly just a starting point for more MCU fic, after all! Please give credit to builtinacavewithaboxofprompts if you use any of them (and tag us so we can reblog your fic!), and also feel free to submit your own MCU prompts via ask/submit, especially for movies and shows that are not my primary focus!
