>>47522872I think using existing pokemon types would unironically give more flavor. Rather than outright fanfiction you would be classifying the experiments based on pokemon's parameters.
Stich, Angel, and Leroy would have to be legendaries. Angel I was going to dismiss at first but it turns out that she's like a vaguely weaker version of stitch aside from her singing power.
Maybe have some of the "elemental" experiments as starters? The whole 600 series of experiments are military weapons so they should probably be legendries
