>>54035143The reasons they must not do this are the following three.
1: She's a popular starter AND the new main character's partner, so she can be treated differently.
2: Pokemon are allowed to have accessories anyways, they just can't evolve with full costumes.
3: If she has a mask, there can be a big emotional moment where she reveals her face for the first time. If they say it's skin, they'll be taking that away from her for no reason.
This is why they must not say the mask is skin.
