Kinda personal ‘Screw You’ of the Chauqetrix AU because I do have a bias or two including but not limited to “Don’t write a harem AU for the 10 year old” and my general dislike of too-feminized female alien designs
Br-Omnitrix (Bro-Omnitrix, hehe. Discord friend called it the Chadtrix) where, yeah, Ben is summoning aliens but they’re more like cloned beings based off his DNA and relative personality. Like having a twin but they’re the alien he picks out, which inkeeps with the “Walk a mile in other lifeforms shoes” bit in making a life form basically just like you but a different species as a practice in empathy.
All that changes is that Ben is summoning these aliens (duh) and they actually appear his age and not mostly grown up like they do in Classic, just having his personality and a simulated life like the Ultimates did— basically making each of them a “What if Ben was a (example alien)?” all rolled into the same au.
Zs’Skayr still starts taking over Ghostfreaks transformation but it’s more like seeing a sibling turn into a person you don’t know and that transformation functionally dying to release Zs’Skayr when he breaks out. (You know that jerk is abusing the emotional leverage of the “Don’t hurt me, I’m still in here!” cliche)
And other tidbits from the talk is Ben running around with Julie chasing after Big Chill wondering what the hell is happening to him and if he’s losing another friend/Clone-brother (to include Feedback with Ghostfreak) only to see his kinda-cloned-niece/nephews pop out of a metal nest and Big Chill comes out of the maternal instincts like “Dude, I honestly did not know this would happen”
Angst and comedy potential, roll and run with it, I am never touching Chauqetrix with a 50 foot stick. Just, do as you please with my thoughts
I was also going to say “Ben-Kai Watch AU” but that’s just a ship name and would not immediately make people think “Yo-Kai Watch AU” but that’s, it’s also in the thought process
