The Virus - Gardevoir TF Story (Patreon)

A remnant of Team Rocket led by a woman with lingering ties to their former leader conducts inhumane experiments on Pokemon, culminating in an accident none of them could have anticipated when a Ralts gets exposed to a mysterious stone from another land...

Based loosely on the games and more towards the earlier Pokemon Adventures manga that had a surprising amount of grit and danger to it, liked the way they portrayed Team Rocket and the other groups in the first few arcs so I went with that in mind for this story.
