Again, with Jack Atlas, his boss paid people large amount of money to lose, like the example in the show was that the guy had a counter that would help him win, but he didn’t play it because he needed the money. In Pokemon, it would be not using the full powers of your mons and letting them take damage when they could have avoid it and the like.
And it’s simple: stealth rocks and rockslide, the latter on a mon that outspeeds Charizard’s 100 speed, like Alolan Dugtrio, or who can take the hit, like Heatran. Charizard is a UU pokemon for a reason.
And it would help people to like Hop when him being vulnerable is followed up with reminding you that his brother, Leon, is the undefeated champion.
