Hey! We will allow some minimal effects on personality or character, optionally. However, as Pokemon should be chosen with a goal in mind for character development or growth, we would just ask that any changes in mentality are subtle, slow-growing, and don't stray too far from their original character to the point of making them no longer recognizable.

For example, a soft-hearted character might embrace their own anger more, but it should be realistic around things they do feel anger about and normally hold back. Slip ups that make them feel horrible afterwards, because of the type of person they are. That sort of thing!
