Which of the "rivals" did you like the best in Pokémon Scarlet/Violet? I only say rivals like that because I'm not sure if Arven and Penny really count. Nemona definitely is a rival though.

Clearly, Arven is the best character. He has the best story and personality. However, I really like Penny and I draw her all the time. So, my ranking would be;

1. Penny (she is my girl, I draw her so much and I want to write about her so bad)
2. Arven (even though he should be number 1 on all accounts)
3. Nemona (I like her enough, but she's the weakest link)

But, honestly, I like them all.
