>>45368717I like the idea of different pokemon a lot, but yes, usually people just do shinies or shadow pokemon or something else that's already established by the game.
The fantasy supplement for PTU has a bunch of really neat pokemon variants that I honestly wish were real. Honedge based on different swords like rapiers and kopis, klink and voltorb that used to be part of some kind of Antikythra mechanism, customizable homunculus Reuniclus, really neat stuff. A martial artist trainer who uses a taijijian Honedge could be fun. Maybe it becomes shuang gou when it evolves into Doublade, and for Aegislash it becomes the Sword of Goujian and a rattan shield.
