i wish ash won the sinnoh league championship. i think the writers got bored of him having infernape and pikachu and decided "that's it, create a character with a team of legendaries and mythicals"
they also made ash a lot dumber by the end of that series, like whe he was using his gible and torkoal against tobias when he should have used charizard or infernape or snorlax or something
