This is just a thought in regards to one of the 2 members of Alain's team that are still unknown, but if you compare his, Sawyer's/Shota's, and Ash's Team you will notice they all have Pseudo-Legendary pokemon and here is the break down of that:
Ash: Goodra
Sawyer/Shota: Salamence
Alain: Metagross, and Tyranitar
and if you compare Ash's and Sawyer's/Shota's Team you will also notice that they have a Semi-Pseudo Legendary pokemon(basically it is a pokemon that is often mistaken for a Pseudo Legendary pokemon but does not meet the criteria to be one.) and here is a break down of that:
Ash: Noivern
Sawyer/Shota: Slaking
Also here is a list of the Semi-Pseudo Legendary pokemon:
Kingdra
Slaking
Aggron
Flygon
Lucario
Haxorus
Zoroark
Volcarona
Noivern
so maybe since Ash, Alain, and Sawyer/Shota all have Pseudo-Legendary pokemon and Ash and Sawyer/Shota also have a Semi-Pseudo Legendary pokemon then maybe Alain will have one as well. So if we also take into account that it seems like Alain is going to have a pokemon that represents each generation(1-6) then we can narrow it down through the process of elimination of which one Alain might wind up with and here goes:
Okay since Alain already has a pokemon from the 2nd, 3rd, and 4th generations then we can eliminate Semi-Pseudo Legendary pokemon from those generation as he won't get them if he is only getting 1 pokemon from each generation, so that eliminates these pokemon:
Kingdra
Slaking
Aggron
Flygon
Lucario
Which leaves us with Haxorus, Zoroark, Volcarona, and Noivern. Also we can eliminate Noivern since Ash has a Noivern and there probably not going to give Alain a pokemon that Ash is currently using on his Kalos Team. So that leaves these last 3 options which are all generation 5 pokemon:
Haxorus
Zoroark
Volcarona
Now also if you notice between Ash's, Alain's, and Sawyer's/ Shota's Teams there is representation for 15 out of the 18 types that exists so if the writers plan to have it so that between all 3 teams combine all 18 types wind up getting represented then the 3 remaining types that need to be represented are Bug, Poison, and Ground and there is a way this works with Alain getting a Semi-Psuedo Legendary pokemon and then one more pokemon that will represent the last 3 types then here is how that works:
If the writers give Alain a Volcarona then that gives Alain Alain a Semi-Pseudo Legendary pokemon which also happens to be a Bug/Fire type, and then the only way that the Posion and Ground types could still be represented without being left out would be if the last pokemon was a Duel Poison/Ground type pokemon, although the only pokemon that fit that typing would be Nidoking and Nidoqueen which are generation 1 pokemon, so maybe like some one suggested Mega Charizard X is Alain's representive for gen 6 and then he winds up getting a Nidoking or Nidoqueen for his last pokemon.
So maybe Alain's Team for the league will be this:
Alain's Kalos League Team:
Charizard<-->Mega Charizard X
Metagross
Tyranitar
Weavile
Volcarona
Nidoking or Nidoqueen
so what do you think?
