There was a Kid vs Kat AU that I made in 2023 called Moved On Coop AU, it was basically the aftermath of The Kat Went Back where Coop's life hasn't been the same, with Millie, Lorne, Harley, and Fiona losing their memories of Kat, Dennis Chan ends up becoming Coop's enemy because of a reason that was purposely added onto the AU.
Reason: Dennis Chan had enough of fighting Kat and he wanted a break from it.
Eventually, Dennis and Coop ended up arguing, resulting in them to stop being friends and Dennis became somewhat a bully towards Coop in the AU. Which was the worst decision ever that I've ever made in this AU.
Then Coop was forced to stay with his aunt due to circumstances that I didn't include in the AU, and he made new friends, he got a girlfriend name Joyce. A year later, he saw his old friends again and they became rivals since, eventually leading to somewhat friends but enemies.
Trust me, I don’t regret making the AU but I regret making Dennis Chan a jerk towards Coop, I could've made him ignore Coop or something but the whole purpose of the Gacha community (at least to me) is out of character development is kinda normal unless said otherwise and yeah, obviously, I do regret making Dennis an idiot.
It was in 2023 when I was a teenager, struggling with mental issues and I had the idea for a very long time before I made it come true.
It was in Gacha style, check out my channel with the handle: AutisticGirl2008 and see my old videos, you'll understand it.
If I do plan to remake it, I would like suggestions for it.
