With the 8th Gym badge on its way within the next 5-7 episodes, we're nearly on the road to the League and since everyone is now discussing the league, rivals and battles, I thought it would be better to make a separate thread for it... I might also edit this post as we get more information.
For the purposes of this thread (or just my post), I'm going to assume Ash will use reserves as it seems very unlikely Noivern plus new 6th capture or Goodra will be used in most of the battles, also with 3 Pokemon being weak to Electric and Ice types each, his team is at a high disadvantage if he uses just this 6.
I will also assume Alain will NOT be at the League until we get credible reasoning to believe so.
Also, the writers are smart enough to know that Sinnoh League was by far the best, and one of the reasons was we got to see the old guys return. And if they want XY to stand as an amazing arc, they should do the same here, because more often than not, Leagues make or break a series. Most of us hate BW due to the dreadful league and rivals, XY has already done a pretty good job with the rivals, but we do need to see more...
Anyways, the way I see it, first round will be similar to BW, with Ash facing Trevor in 1-on-1, it could be a 3-on-3 like the battle with Nando, but I believe Trevor hasn't got much development, and seeing him with 2 very new Pokemon could be too much.
So, Round 1:
Ash vs Trevor
Talonflame vs Charizard, wins
In Kanto, Hoenn, Sinnoh and Unova, the round 2 opponent was either not shown or only one battle was shown, I believe the same will happen here but with a twist, I see us only seeing the 2nd/3rd part of a 2/3-on-2/3 battle, or a double battle, and I believe we will see either Gible, Totodile, Pignite or Snivy evolve, though the latter two may not appear in the league at all since they are very recent.
Personally, seeing Gible or Totodile evolve would be the most fitting.
Ash vs Tierno, like Sinnoh and Unova, Ash should also be facing a rival here, this battle could either be a double battle or a 2/3-on-2/3.
Interestingly, though I doubt it will happen, I'd like to see Squirtle coming back, for this post, I'll consider Squirtle coming back as we do not know any other Pokemon Tierno's and Ash's have a rivalry with.
For a double battle:
Pikachu and Squirtle vs Raichu and Blastoise, would be very fun to watch and quite interesting too
For a 2-on-2 or 3-on-3:
Pikachu vs Raichu, wins
Pikachu vs (Mega) Blastoise, loses
Squirtle vs Mega Blastoise, wins
[Squirtle gets knocked out by a random 3rd, which Goodra finishes off, or Goodra also beats Mega Blastoise if Squirtle cannot]
Final rounds (full battles):
Now, since I believe Ash will minimum get to the semis, possibly final, I don't see top 16 battles happening, as we've only ever had maximum 3 full battles in a league (in Hoenn) and I can definitely not see 4 happening, however if there is a top 16 battle, I believe we'll only see the end of it, and possibly get a sighting of Ash-Greninja so that everyone knows about him and that Ash gets hyped up
Top 8 battle:
Unless Ash is destined to lose at the semis while still battling Sawyer, the top 8 battle will NOT be against Sawyer, this will be with a COTD, and we will hopefully see a good battle akin to Ash vs Katie of the Hoenn League
Top 4 battle:
Ash vs Sawyer
I have pretty much figured this battle out and I believe this is very predictable.
Now, I am still unsure as to who will win this match, but I believe it goes 70-30 Ash's way, and this is how I see it going.
Noivern vs Salamence, tie
Hawlucha vs Slurpuff, win, or tie, if it wins, Aegislash will knock it out
Pikachu vs Aegislash, win
Pikachu vs Camerupt, lose
Corphish vs Camerupt, win
Corphish vs Clauncher, during which Corphish evolves, this will either be a win or tie
If Corphish wins, it will then be knocked out by Sceptile
Ash-Greninja vs Mega Sceptile, I believe Greninja will get knocked out leaving Sceptile at 33% health, this will also show how very Sawyer has come, being able to beat the Pokemon he has studied so hard against and kept continuously losing to.
Ash's Sceptile vs Sawyer's Mega Sceptile, though a close battle, Greninja weakened Sceptile too much and Ash's Sceptile is able to finish off his hard work.
Wow, Ash makes it to a final for the first time, for the sake of preparing for an Elite Four challenge and an epic battle, I hope he uses his best six Pokemon he has, even if he's to lose the match, I have no idea how this battle will go and who will win, but I reallly hope Ash uses these 6 Pokemon:
Goodra/Snorlax/Krookodile (whichever one doesn't get to star in the top 16 and top 8 battles)
So, that's it from me, what do you guys think?
