JoJo's Pokemon Adventure: Kanto Crusaders

(Note: This happens after the Crusaders get Polnareff and Ash becomes the Alolan Champion) (Spoilers for JoJo's Bizarre Adventure, Also Pokemon if you haven't watched Pokemon, ever) In the JoJo universe, the Crusaders, who just befriended Polnareff, are at the dock, ready to board the ship to take them to Egypt in a few weeks. After the plane crash that happened yesterday, they aren't willing to take a vehicle with other people in them. Suddenly, a rip from the Time-Space continuum appears under Jotaro Kujo, making him fall in. The others, Joseph Joestar, Muhammad Avdol, Noriaki Kakyoin, and Jean-Pierre Polnareff try to help, but get dropped in as well, Jotaro's mother, Holly Kujo, also gets transported through the rift. After what seemed like an eternity of falling, they finally land in an unknown place, full of mysterious creatures. But one thing was for sure, they were in for one heck of a adventure!
Ash Ketchum, hailing from Pallet Town, has just become the Alolan Champion, coming back to Pallet Town to celebrate his triumph against the Melemele Island Guardian. After a rest, he went to celebrate his victory at Professor Oak's Lab, along with Gary Oak. After a party, he went to take a walk with Charizard, Pikachu, talking about his old adventures along the way. Suddenly a bunch of rifts appear in the sky, all with people falling from them, Ash was curious, but he did not let curiosity get the better of him, as he kept walking.
What they didn't know, was that someone was watching them, with a bow's string drawed and a particular yellow-tipped arrow in the bow's string. Smiling with malicious intent, he let go, piercing Ash's Skin and hitting him in the leg, but what's special about this arrow is that it's a Stand Arrow. And while this was happening, the Crusaders were finding their way around the forest, Jotaro found a way out and told the others via shouting, while the others were heading Jotaro's way, Jotaro saw that Ash got pierced by an arrow.
