Invincible Pokémon Brothers

The Invincible Pokemon Brothers are a trio of brothers that use Fighting-type Pokemon, more specifically, The Hitmon-trio evolutions. Both are the main antagonists of "Gotta Catch Ya' Later" and "Cerulean Blues" were they pester Misty on challenging them to a battle. They resort to cheating, even in single battles. For example, Kai, the leader of the group's Hitmonchan would get beaten by Misty's Politoed, the other two brothers would illegaly send in their two other Pokemon, Hitmonlee and Hitmontop to outnumber Politoed, but ended up being defeated by Ash's Pikachu and Brock's Forretress respectively. Turns out, The Pokemon Brothers were in cahoots with Jessie, James and Meowth of the Team Rocket trio, only because the TR trio promised them gold, but it turns out that the trio had lied to the Pokemon Brothers. Ash's Pikachu, Brock's Forretress, and Misty's Politoed all attacked the TR trio and the Pokemon Brothers sending the six of them blasting off into the sky.
