A man grown up in isolation solely with Pokémon suffering, developing an unshatterable ideal of a world where Pokémon and humans are separate in order to save the former from suffering, going through exteme and hurtful measures to acquire a legendary Pokémon with whom to achieve his ideal. You challenge him to stop him, but because he has developed doubts on his journey about his own ideal, he desperately is looking for someone to challenge it.

And right before he is about to exert his dream, the other Mon representing the opposing concept appears, seeking to fight by your side. Kickass music appears. You catch it. The fight begins. He sends Zekrom/Reshiram, you send yours right at the beginning and it is finally decided which dream is the correct one. N gets his strength from wanting his friends to be free, your team gets its strength from Pokémon and humans helping each other, so the team which is stronger is simultaneously proof that its dream is the correct one.

Make a better climax - in a kid's game - where the entire game, its ideas and concepts flow in
one final battle like this, and as well as this.
