Brago

The Pokémon Poacher Brothers are a trio of brothers who catch and steal Pokémon.

Season 5: Master Quest
Brago, along with his brothers, Chico and Blurt, were the poachers, who wanted to steal the egg from Tyranitar. However, their plan failed, though Larvitar had the nightmares of the brothers. When the heroes returned with Larvitar, they went to capture both Tyranitar and her child. However, Tyranitar, who was captured, saw Larvitar in fear and managed to use Hyper Beam to blow them away. They were soon arrested for the crimes.
