Pokemon Legends: Bill

Dipper disappears. Mabel, Stanley, and Stanford are so determined to find him, that they build a portal. Unfortunately, Stanford gets separated from the other two, and ends up in another place, with no memories. The people who live there call it Hisui. He feels uncomfortable, out of place there. Yet, it gives him comfort to see two others with no memories: Ingo, and Mason.Meanwhile, Mabel and Stanley are in a place which is apparently called Nimbasa. They lost their twins. Thankfully, they meet a man named Emmet, who also lost his twin. The three of them gang up together to try and get their twins back.AKA as that one au where Bill nearly dies, possesses Volo, makes Arceus distressed leading to Dipper ending up in Hisui with no memories (meeting Ingo and Stanford who both also have no memories), while the other three twins (aka as Mabel, Stanley and Emmet) sow chaos in Nimbasa on their quest to find their twins.ALSO Stanford thinks his name is Stanley, and Dipper kinda thinks his name is Mason (it is, actually. he just prefers to be called Dipper)
