Shauna the amorous rival, she could be the main rival, she challenges you more often and her team could have more pokemon. The final battle she has a full team of 6 pokemon and has some strategy in use.
She could romantically flirt with you irregardles of gender (E rated of course).
After the league she finnaly get a passion for pokemon breeding and she could be found in her home town middling her bussines, you can challenge her once per day but she battles you in a triple battle and now she has a team of 3 Blisseys level 100 with suicide movepool (as a thing part of her new pasion in breeding).
This battle can be changed if you contact her via holo caster and invite her in a date in any city. You will find her in a cafe and the date start with a pokemon battle with her old team but now is a real challenge.
