In every game, we fight the villain boss, we save the world.
But what about the Champions? They never fight against the bosses in the games - except for Steven Stone in Emerald, but he wasn't a champion in that version.
Same goes for the anime. They help, but don't fight.
Do you want to see the battles of Champion vs Villain Bosses? If so, what do you want to see?
For me, I want to see Alder vs N. They actually battled in the games, but when we arrived at the scene, we were too late and missed the big fight.
