This is basically if Dipper and Mabel became superheroes.
Dipper would have flight, heightened senses, and the ability to sommon a giant battle hammer at will, all at the cost of becoming color blind and dyslexic.
Mabel have have flight, bio-illumination, and the ability to shoot shooting star shaped energy out of her hands.
Dipper and Mabel gain these powers by accidentally touching a strangle, purple rock called a Powerite. Together, they have to save Gravity Falls from super villains like Gideon, who has telekinesis, and Pacifica, who can turn anything she touches into gold.
Also, this au would likely consist of Dipcifica somehow, but that’s optional.
