Maybe it could have a random evolution between now and BW025, or during the gym battle. Dawn's Swinub evolved into Piloswine in DP104, so evolutions can be somewhat random without the Pokémon being focused on for the episode. Or, Pidove could evolve during the gym battle and get a win.
Swinub was a random pokemon.. A Dawn pokemon with no character traits that set it apart from other already known pokemon.. The only thing that saved Swinub
was evolving..
If DP104 was called:
Darkrai vs Cresselia! Swinub follow your nose!! Then nobody would've called Swinub's evolution random, as it made sense as how Swinub had a bigger then average part in that episode and was specifically called on for its strong sense of smell. Using that to locate Cresselia by tracing the scent of Dawn's Lunar Wing. But since it wasn't explicitly mentioned in the title, it's somehow random.
That being said, how many pokemon of Ash's have evolved randomly? The only one I can generally think of from the top of my head was Torterra in the Sunyshore Tower episode... It wasn't used for any specific reason other then to fight Team Rocket on one occasion and it just evolved.
Ow, and Quilava was kinda random as well, but it got some build up all the way from the time it was in Johto when Ash wanted it to evolve.. but didn't.. Gosh, I hope might is reading this..
This is how i think it will go, Ash's Kurumiru, should be in this battle because
I only think the bug should be in the battle because it's stage 2 evolution is possibly with Arty.
Think about it
Lt. Surge: Pikachu faced Raichu
Winnona: Swellow vs. Swellow
Gardenia: Turtwig vs. Turtwig
Crasher wake: Buizel vs. Floatzel
I think whenever Ash has a Pokemon on his main team, that a gym leader also has, or the pre/evolution of it, they want them to face each other.
So Tsutaja vs. Ishizumai, Tsutaja
Fushide vs. Mamapeto, Mamapeto recalled
Fushide vs. Tsutaja, Fushide,
Mamapeto vs. Fushide, Mamapeto (It might of already evolved, if not i hope this is where it evolves)
Kurumiru vs. Hahakomori, Hahakomori wins
Hatoopoo vs. Hahakomori, Hatoopoo.
By that reasoning, we should also have to see Fuuro's Kenhorou vs. Ash's Kenhorou when the time comes. That would mean that Kenhorou would've had two gyms to star in.. Which is a lot for a bird, especially considering that this bird has done nothing impressive yet at all. And if so, the gym pickings would probably look something like this:
Sanyou: Mijumaru
Shippou: Mijumaru (unless they let Miruhog be the lesser and make Haderia out to be the star of Aloe's team, then it would be Pokabu)
Hiun: Hatooboo (according to you)
Raimon: Meguroko? Waruvile? Pikachu? Tsutaja? (If Meguroko becomes part of the team at that time)
Hodomoe: Tsutaja? Mijumaru?
Fukuyose: Kenhorou (according to your logic)
Sekkai: Pokabu (evolved I think -> Enbuoh vs. Tsunbeaa)
Souryuu: Pikachu?
Lol, if Ash has Waruvile by the time he reaches Hodomoe, and Iris has Doryuuzu.. That would make Yakon's line up seem like complete pushovers except for his.. Gamagaru.. Since they're already on the team and such..
Really? Can you post a link to where you heard that? Either way, what is so wrong with Arti having a Hahakomori anyways?
Nothing wrong with Arty having a Hahakomori, but you said that the Kurumiru that's basically confirmed to go to Ash will become his. I think that was his point, not objecting to Arty having a Hahakomori..
