I have this idea you see.
And I want it to be the best like no one's ever was.
All kidding aside, I've been attempting to form something that was a bit more....offbeat you can say. It takes place about seventy years after Ash (year 70AA haha...not really). Over time, people have become much more frightened of Pokémon (pó as they're now referred to as), and have even evacuated Hoenn and Sinnoh completely, building bubbles over their cities to protect themselves. Much of the story is set in the Kalos region. To travel now, everyone uses a teleportation system which our protagonist's father's company produces and "gym battles" are now huge events in a stadium, where there are "masters of elements", "stadium leaders" you face in front of a huge crowd, a bit gladiatorial, since trainers are much fewer, and train at highly specialized training grounds. Pokémon are bred tamed in the city limits, and everyone keeps one for protection (bought from trainers). Everything is rationed and distributed so that the city can be self sustaining.
So there's a bit of background to the environment. As for the story line itself: it begins with Cara writing a letter to someone, but there's no background of their relationship or who they are. Simply, it says, "it's been quite awile since I've last written you. I'm sorry for that, my dear friend." Okay, so you know they're close. We'll get to that in a moment. A friend visits and the world become unveiled, with her friend (Vikki, a dark-type "stadium leader", who Cara knows because her husband designs technology at, now, Cara's company) remarking on Cara's (foolish) bravery of staying in her parent's old house in the "countryside". She continues making comments of how dangerous it was to travel there (in a tank like vehicle, have you). She convinces Cara to come to the city for "Ash day", a huge festival every year which his grandson (obviously) funds. His grandson is now one of the "mayors" or whatnot of the city. Young and foolish and too rich for his own good, namely. When Cara visits Lumiose for Ash day, she is coerced into registering to compete in the annual tournaments to "live a little" and "have a bit of fun while in the city". Since her family name is widely recognized, she registers as "X" (idk, I love playing as trainer X in the games; it sounds BA). She shocks everyone by demolishing every trainer (since no one knows of her, they think she's rigged it), so Ash's grandson, who HAS met her (discussing business) steps up to face her to help her save face. Epic battle, fun, fun. It's not going to center around this at all. I just want to give Cara a bit of ethos as to why she'd be chosen to perform in an epic task, and to show how shoddy training has become; more of a game of chess with complete detachment from their Pokemon.
