What will Serena evolve her eevee into?
I'm hoping Sylveon
Confirmed to evolve into Sylveon
Skip to 43 minutes in, you can see it evolving into Sylveon
Different anon here, but I feel like Pancham is sort of like Clemont's Chespin/Ash's Oshawott in the sense that it's cute and marketable on it's own without the need for it to evolve. It also helps that Chespin and Pancham clash a few times.
if she gave a damn about the looks she'd go for leafeon
That's my bad, I thought Pancham was also Dark.
Anyway, it could always evolve using Greninja or James' Inkay. I could definitely see the writers bending the rules like this if they want Pancham to evolve, it'd be similar to how Ash's Sliggoo bent the rules (evolving from its own Rain Dance, which doesn't work in the games)
