Here's a weird idea: MLP and Subnautica crossover. It seems weird, but maybe there's some potential for an interesting story somewhere? Maybe the mane 6 are stranded on it's planet and have to find ways to survive out in the world around them? Or perhaps an OC? I don't know, I haven't seen anyone do it yet, so why not?

Very interesting... I'll look into it but I have a lot of fics on hold.

4662987 Seeing as how no one has actually come back to this thread, me recently playing the game so much with the Precursor update, I can see how I can write such crossover.

It starts with the Precursors making the first Warper, but teleportation gates open up in Twilight's Map room where Twilight is, one in Pinkie's bedroom where's she's sleeping at and one in Big Mac's room. The experimental Warper projectiles hit the three ponies causing them to transport rapidly all around Equis until they went through the gate which brings them to the safe shallows.

Then the story begins there.
