So my thought process was that we will get a Z-move for each type and depending on the move used when activating the Z-move ex thunder/volt tackle it will be either physical or special.
But since some pokemon get signature Z-moves will these even be stronger? And maybe they will activate a form change like Ash-greninja? And what about if they are physical/special? Will it be depending on the move used or will they be already split into categories from the start?
