Steven Universe/Gravity Falls Crossover

Fun little Steven Universe/Gravity Falls Crossover idea…

Instead of Lapis being the mirror gem, its actually Bill. Sealed inside a mirror and thrown through the portal into another universe. Steven’s universe. This immediately weakens him since he draws power from what he knows. What he knows is determined by how much he can see through his peepholes. You know, any little drawing of him.



He’s weak because there are no images of him in Steven’s universe, not even on the currency. This is probably why he was thrown in the portal in the first place, Dipper or whoever figured that they’d at least throw him somewhere he would be powerless.

So he’s stuck and discovered by, I dunno, Rose or Pearl or someone and put away (they sense the danger or something, idk) until Steven gets his hands on him couple of years later. Being the charmer he is, Bill manages to get himself free with Steven’s help.

Anyway, so as soon as he’s out he pulls Steven into the mindscape with him and introduces himself. Up until that point he had been unaware that he was in a different universe so he uses too much energy isn’t able to keep Steven long and vanishes, though he tries to keep an eye on him using any little accidental images of himself that he can.

Eventually when he does realize his power has been severely cut and he’s stranded (maybe even still injured? He’d have to be in order to be defeated in Gravity Falls), Bill kinda panics.

Using as much as his power as he can, he puts Beach City to sleep. This effects everyone except the Gems because they don’t sleep and Steven because he’s half Gem. The reason? He needs people to dream of him. If they dream, they’ll write it down. Draw him. He’ll be an inspiration and eventually his image would be spread around just as it had been done in his old universe. He’ll gain power and become strong enough to return to the universe of Gravity Falls.

This is the plan, but he’s sloppy. He’s trying to do centuries of work in one night and the results could be fatal to those of Beach City.

The problem the Gems have is that they can’t see him and fight him. The only way to interact with Bill is to be asleep which the Gems simply can’t do. That leaves it up to Steven. None of the Gems want him to do this, not even Garnet.

Of course, he does it anyway. He finds Bill and is given a summary of what he’s trying to do. At one point Bill realizes that Steven himself might be a kind of battery whose energy he could take from his gem. When he tries (acting innocent as though he’s just curious about the gem) Steven’s shield blocks him. (”…Ow”) The forces Bill to realize he should stop and learn about this place instead. Steven is happy about this and insists there are a bunch of places Bill can live. He’s seen them since he’s traveled around with the Gems so much.

Bill manages to convince him to put images of him wherever he goes. (”Just so I can take a peek at the area myself, kid. You do this for me and I’ll avoid messing with this town, deal?”)

(Sorry, have only drawn Steven twice before… and that was like 2 minutes before this.)

Beach City wakes up with no ill side-effects, thankfully. The Gems don’t like the deal at all and are suspicious of Bill, whom they still haven’t seen.

And… and that’s all I’ve got so far. Maybe I should finish watching Steven Universe. Ha.

Ima go crawl in my hole now.
