Here goes my first team guesses. These are my ideal teams for everyone. Not what I think will happen, just a personal wishlist
Ash
[IMG139]http://floatzel.net/pokemon/black-white/sprites/images/25.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/3/36/Spr_5b_521_f.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/503.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/498.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/496.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/553.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/620.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/613.png[/IMG139]
Pikachu-No brainer.
Mamepato --> Hataboo --> Kenhorou-Since Ash's birds always evolve all the way, I can't see this one being much different
Mijumaru --> Futachimaru --> Daikenki-I think Mijumaru will definitely evolve all the way. Will be Ash's major powerhouse.
Pokabu-I think Ash could use a mini-powerhouse and Pokabu would be perfect. Plus I don't like Pokabu's middle evolution and I don't see it evolving all the way.
Tsutarja --> Janovy-I'd like to see one starter in their first stage, another in their 2nd, and one in their final. I like Janovy better than Chaoboo, so I choose Janovy to evolve once.
Megoroco --> Waruvile --> Waruvial-Will probably hatch from the egg. Evolves all the way.
Kojofuu --> Kojondo-If Meguroko doesn't hatch from the egg, I'm think Kojofuu will. If not, I'd love to see Ash with another pure fighting type, and Kojofuu would be a sweet Pokemon. Could evolve into Kojondo at the 7th/8th gym or in the league.
Kumasyun-Ash needs another Ice type, and Kumasyun would be perfect as a Gible-type capture. It could be a shy little baby that is bullied by other Pokemon and rescued by Ash, sort of like Torkoal. Could eventually evolve, but I can't see that happening unless there's a filler saga after Isshu.
Total Evolutions: 8
Iris
[IMG139]http://floatzel.net/pokemon/black-white/sprites/images/612.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/530.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/560.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/587.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/633.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/b/ba/607.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/3/3a/Spr_5b_621.png[/IMG139]
Kibago --> Onondo --> Ononokus-Kibago should fulfill its dream
Doryuuzu-Pretty much confirmed at this point.
Zuruggu --> Zuruzukin-I think it fits her well, and should go to Iris. Should evolve, it doesn't look much different from Zoruggu, so I don't see why not.
Emonga-I can just see Iris swinging on trees and Emonga gliding behind her. Can ride in her hair and share a rivalry with baby Kibago.
Monozu-I can see Monozu having an attitude and having issues listening to Iris. Might evolve, but I'd prefer it if it didn't.
Hitomoshi-I could totally see a Hitomoshi with her. Looks like a Pokemon she'd be interested in. Very cutesy, but a mini-powerhouse.
Crimgan-Either a Pokemon she has only for gym battles or maybe she gets it as a gift from Shaga near the end of the saga and leaves one of her other Pokemon at the gym and brings Crimgan with her, or she only uses it for the gym battle and leaves it there. Either way, I see Crimgan debuting under her care.
Total Evolutions: 3
Dent
[IMG139]http://floatzel.net/pokemon/black-white/sprites/images/512.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/506.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/4/45/581.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/4/47/586S.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/c/cb/Spr_5b_583.png[/IMG139]
Yanappu --> Yanakkie-I could see it evolving near the end of the series or in a filler arc (if there is one).
Yooterii-I can see it acting as a group pet, and being hyper. Wouldn't evolve.
Koaruhie --> Swana-Fits him perfectly IMO. Very elegant.
Shikijika --> Mebukijika-Another Pokemon I can see fitting perfectly on Dent's team.
Vaniputchi --> Baniricchi-Dent's associated with cooking and food, the ice cream Pokemon just seems made for him.
Total Evolutions: 4
Jessie
[IMG139]http://floatzel.net/pokemon/black-white/sprites/images/528.png[/IMG139][IMG139]http://archives.bulbagarden.net/media/upload/f/f3/Spr_5b_573.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/576.png[/IMG139]
Koromori --> Kokoromori-Can totally see it evolving, I just hope it gets a few episodes as a Koromori, to shine and give it some personality first.
Chillarmy --> Chilaccino-I can see Jessie with a stuck-up Chillaccino.
Gothimu --> Gochimiru --> Gochiruzeru-I can see it with Jessie as one of her prized Pokemon. Caught as a Gothimu.
Total Evolutions: 4
James
[IMG139]http://floatzel.net/pokemon/black-white/sprites/images/569.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/556.png[/IMG139][IMG139]http://floatzel.net/pokemon/black-white/sprites/images/579.png[/IMG139]
Yabakuron --> Dasutodasu-Perfect for James IMO. He could use another Poison-type, hasn't had one since Weezing.
Marakacchi-Another Pokemon perfect for James.
Yuniran --> Daburan --> Rankurusu-Mirrors Jessie's Gochiruzeru. Caught as a Yuniran and raised all the way up to Rankurusu.
Total Evolutions: 3
(I know this team was already suggested, I just can't see many other choices for James. It's the perfect team for him IMO)
