>>37643131Actually, going by the Trainer Parties V1 text in the assets zip, there's more hard evidence that KOGA was the Ghost trainer at one point rather than Erika, who was seemingly always programmed as Grass (or Grass/Poison), with Agatha as an Eeveelution trainer (matching Oak's elemental starters) and Giovanni as a Flying trainer. I'd believe the idea that, in preproduction, Sabrina may have been designed as the original Ground and Erika was the original Psychic (and the boy that got cut was Bug or maybe Normal). Though that's just an educated guess. Yukata could have been either a preproduction remnant of genuine flub.
