Gravity Falls was not based on a comic. It was a unique creation that emerged from the imagination of its makers, bringing a fresh and engaging storyline to the screen.
One common theme is the clash of good and evil. Since Reverse Falls is often depicted as a more sinister version of Gravity Falls, when the two meet, there's a lot of conflict between the good-natured characters from Gravity Falls and the more devious ones from Reverse Falls.
Gravity Falls is definitely science fiction. It combines elements of adventure, mystery, and science-based concepts to create a unique story. The presence of magical creatures and advanced technologies makes it fit the category.
Definitely not. Gravity Falls is a work of fiction. It has fantastical elements and storylines that couldn't exist in the real world. The charm lies in its creativity and departure from reality.
The Gravity Falls comics are definitely canon. They provide additional depth and background to the world of Gravity Falls and are seen as a continuation and enhancement of the original concept.
One interesting storyline could be the characters from both universes teaming up to solve a mystery that spans across their respective worlds. For example, Dipper from Gravity Falls and a character from Relativity Falls might work together to figure out a strange phenomenon that is affecting both places.
