ash isnt going to use his older pokemon in this league dude get over it...the only reason he did it in johto was because he kind of had to get rid of all his pokemon because he never even expected to travel to johto so i'm willing to bet a lot of money that we will only see one return and thats gliscorTo tell you truth, I am not very happy about Dawn getting Togekiss. Not because of Misty, I couldn't care less what this means for her future or past or anything. But I consider this as a slap in the face of Ambipom. Seriously, if Dawn is allowed to have 6 Pokémon and 2 of them fully evolved, why ditch Ambipom out and switch it with Togekiss? This is something I will never forgive writers.
I must wonder why so many people here are surprised by Buizel not evolving. I think it was inevitable since that Pastoria Gym episode, when it show some loath towards Floatzel. Unless there will be some DP remake ten years in the future, I am not expecting Floatzel in Ash's team. I still think Buizel will be replaced with Totodile for whatever will come after Sinnoh League. Hopefully, Totodile will evolve at least once.
Also, Gible not evolving is no surprise for me. IF it will evolve at all, it will evolve after league. That much was already given. Also, I am not expecting it to evolve fully, it will either stay Gible forever or will only evolve into Gabite.
I am really surprised with both Torterra and Infernape. After Gliscor's release, I was sure Grotle will not evolve, simply because Paul has one. Now, if writers are OK with both Ash and Paul having Torterra, why they feel to ditch Gliscor out? That's simply not right. But on the other hand, it may even more confirm my theory about no Ash vs. Paul battle in Sinnoh league.
As for Infernape, I was really expecting it to go Sceptile's track, stay here for post-league saga and evolve in it. Obviously, I was wrong again. I must wonder though, what this means for Ash's team for whatever saga will be there after Sinnoh League. I am sure writers will not allow Ash to keep fully evolved Pokémon for that saga. Torterra will most likely be switched for Bayleef, but what will Infernape be replaced with? Cyndaquil seems unlikely, even if Dawn will not keep her's for that saga. So either we'll see return of Torkoal or Infernape will simply make that free room in Ash's team for swithing between his older captures. And I think the latter is more likely.
