Demon Twins of the Falls

When Stanly activated the portal, he did it with the intention of getting his brother back from whatever dimension he lost him in. He did not anticipate what he'd lose in his efforts. Dipper and Mabel Pines were flung across the multiverse. They managed to return to the falls, at the beginning of their journey. Turns out time is a relative concept. What will happen when they realize they are no longer humans, but now share a species with a demonic Dorito.

I've decided to branch out from MHA content. I'm going into Gravity Falls First since it's my favorite. You might have seen this posted somewhere else. That was a secondary account. I posted it there before deciding it'd be best to just post it here. It will be removed and won't be updated any further on that account.
