Disney Channel Rewind Scholarship

My two favorite Disney shows are The Owl House and Gravity Falls. These are two popular Disney shows that are already suspected to be connected somehow, and my crossover would double down on that. The title of the episode would be "An Old Friend" and the story would follow the main character's mentor, Eda, telling a story about one of her "old friends." This friend would be Uncle Stan, from Gravity Falls, and he'd too would be telling the ones he raised about a witch who couldn't be captured and had spent years trying to find. This witch would of course be Eda. Eda, if you don't know, likes to play around a lot, and this was especially true when it came to her childhood self, hence why she'd consider Uncle Stan to be a friend instead of someone who tried to capture her. Later in the episode, the two worlds would cross as Bill Cypher makes one final grand return and makes the two worlds begin to clash together since he is all knowing and all powerful, abling him to bend reality as he so pleases. The two groups of the main characters would then have to get together to stop Bill Cypher, or delay him as best they can as King, the little guy (didn't want to spoil anything about him) for The Owl House, would get be sent to search for a way to contact The Collector, another world bending entity who's also a child. His only limits are that he's restrained by magical power like all others in the Boiling Isles. With the two groups together, they'd all start planning while Bill himself is plotting as well. Bill plans to overtake every world imaginable, starting with the Boiling Isles, but he underestimated their magical power. Not wanting to be seen as a coward when he's supposed to be some world conquering diety, he continues his conquest, one that he might just win unless something big is done against him. The only thing that would stand a chance is illusion magic so powerful that it tricks the all-seeying triangle with a top hat into thinking that he's trapped himself, but more on that later. Stan and Eda would be constantly motioned towards one another by Mable from Gravity Falls and Luz from the Owl House. The two children find that they share a lot in common, with the main difference being that Luz was more out there than Mable was with her more standard girly expressions. The rest of the groups would be planning more, recommending different things, and occasionally teaching Dipper various aspects of their world and magic, eventually going on to show him glyph magic. Of course, this wouldn't be a Gravity Falls crossover without Soos, the big, lovable guy who can always be found with his signature cap, question mark shirt, and cargo shorts. He'd be in the human world still, watching over the Mystery Shack as a familiar face in the form of Lilith with Hooty (the main reason why the Owl House is called such). From there, Soos would have various interactions wirh other characters, giving more comedic relief. To wrap this all up, it'd be revealed that Eda and Uncle Stan were once together, and how that relationship went could be revealed further down the line. Everyone manages to lure Bill into their trap, and while he didn't fall for it as first, he would a second time, then erase himself before he went mad, and this process was far shortened by The Collector, and that concludes my crossover episode.
