From Bulbapedia, the community-driven Pokémon encyclopedia.
These are my predictions for the main characters' teams in the anime!
I just think that Chimchar will evolve. Once. Yeah, yeah, I know, everyone wants Chimchar to evolve ALL THE WAY, but save that for the BF.
I think Piplup will FINALLY evolve (It's LOOOOOOONG overdue), as will Buneary after giving up on Pikachu. Why Dunsparce? I like it, and I think it's severely under respected. NEXT!
Brock gets a Beldum, and then, around the time of Sunnyshore, Beldum evolves!
Jessie FINALLY lets Seviper go, and replaces it with a Kecleon to aid Wobbuffet in being annoying!
James gets an over-affectionate Slugma!
For the BF, Ash leaves Gliscor, Grotle, and Buizel at Oak's and takes along Corphish. He subequently captures a Carvanha. By the third Facility, Corphish evolves into a Crawdaunt, and shortly afterwards, Monferno also evolves! Yay!
Dawn recieves an Eevee after leaving Zangoose and Pachirisu at home, and near the end of the BF, Eevee evolves into a Leafeon, possibly in Ilex Forest. She catches a Snubbull, which quickly evolves into a Granbull.
Happiny and Metang evolve.
Jessie gets her Lickitung back, and one episode later, it evolves.
James gets his Cacnea, now a Cacturne, back. Slugma eveolves.
