Latest: Crossover - Pokemon
As useless as Orion was in a battle, he was Dipper's first partner pokemon, the one he'd been given along side Mabel's Eevee Comet back when we were ten.

He heard running and, before he could even get a proper look at his surroundings, bumped into a very familiar face.
“Marilyn?!”
“Andrew?!”
They heard more running and Marilyn grabbed Stan by the hood. “What the–?! Hey!” Stan was lifted from the ground and onto a flying stick. He could've sworn he was high because this is straight out of an acid trip, “No time to explain, let's go!”

Summary
As Ford flew one way, Stan went the other.
The freezing heat of the portal caressed at his skin like ocean waves lapping the shore. The sensation was intense, overpowering everything else. He couldn't even feel the brand on his shoulder anymore.
Before the maw swallowed him his eyes locked on his brother. Ford was screaming his name, hand outstretched.
“I’m sorry.” Stan choked out.
Then, all he could see was light.Series

Summary
Pacifica Southeast was supposed to hate Mabel Gleeful forever. It was easy—after the betrayal, after the blood, after the summer the world nearly ended. Every year they’d see each other again. Every year they’d fight harder. Every year the fire would burn hotter.
But hate curdles. Hate twists. Hate starts to feel like longing when no one else ever got under your skin quite like her.
Now, the forest is breaking, the old magic is waking, and the only person Pacifica might trust to fight beside her is the girl who ruined everything.
Mabel Gleeful has never apologized.
And Pacifica isn’t sure she wants her to. -

Summary
"Pines." A voice barked. "Up."
Ford dragged himself off the bench on numb legs. He didn't dignify the officer with a glance while he rolled open the cell door, brushing past them just slow enough they could keep up.
His brother stood at the front desk of the precinct, looking about as sour as usual. "Ford, what the hell." He said, like he'd said a dozen times before.
Ford rolled his eyes. "She was the one that stole from me. I appreciate my visits here about as much as you do."
(or: Ford is the worst sugar baby ever)

Summary
"Sixer... what did you do?"
“Nine Lives Lee”, a rare Stanley Pines who ended up on the other side of the portal instead of his brother, literally falls into “The Better World”, the dimension that many versions of Stanford Pines tend to be jealous of and hold over Lee’s head as ‘proof’ that everyone would have been better off if he’d just done what his brother asked him.
The Ford of this dimension, however, isn’t quite what he seems. And neither is his version of Stanley.
