Project: Titans -- A Pokemon Story (OC x Piers)
56 parts Complete Special Operative G isn't exactly what you would call a normal girl. She lives with hundreds of other people in an enormous secret base. She can't tell anybody her real name is Gia. She doesn't even know who her mother is. Plus, her father is the biggest crime boss in the whole of Kanto: Giovanni, the leader of Team Rocket.
One day, the 18 year old is assigned an undercover mission in the Galar region; She is to infiltrate and worm her way into the system, and take down the Chairman's businesses from the inside. While Galar is in disarray, Gia must collect all the Wishing Stars she can and then return to the Kanto region.
Special Ops. G has never failed a mission; never had her cover blown, never been caught, and never let her emotions lead her astray. But, when one Gym Leader gets suspicious of her identity, Gia's whole world gets turned upside down.
But there's something else Gia doesn't know. A secret project only Giovanni and select Team Rocket scientists know about. A failed experiment to create a mutation of a trio of legendary Pokemon that failed 19 years ago. Something that could destroy the world if it were to be unleashed...
(NOTE: This story is set post-game of Sword/Shield, but if Leon won the battle with the player. Also, Rose still runs the league, since Leon can't man both jobs).
