this war would obviously end in a fight between the champions
To bad Hoenn has 2 champion and Jhoto has 1
Everybody would be like, noooo! thats not fair! so then Gold, the new champion would enter the attle to make it even, too bad its only canon pokemon is Marill
But for the heck of it, lets say it has Typhlosion, Noctowl, Azumarril, Sunflora, Ampharos and something like a tyranitar or donphan or something
Brendan canon team would be Starter (but it'll be mudkip in this case because lolmanga) Swellow, Camerupt/Magcargo, Tropius/Breloom and Ludicolo/Wailord, but because we're trying to make this even, he'll have Manetric and something cool like salamance or Hariyama or Aggron
So then it becomes a 3 vs 2 battle, and thats when Red kicks in because he wants to get stronger which makes no sense whatsoever, but whatever, he enters with his G/S team because it doesnt repeats types like in HG/SS
Now, it becomes 3 vs 3
Then the matches are at random
it is Lance vs Brendan, Wallace vs Gold and Red vs Steven
Brendan and Gold go to the next round and the battle between red and steven is a tie because metagross used explosion
So it ends up in a match between Gold and Brendan
Swampert > all
Brendan wins
But brendan is a fabulous guy and wants the war to be over because he wouldnt be able to enter his contests
