From Bulbapedia, the community-driven Pokémon encyclopedia.
Brendan (Japanese: ユウキ Yūki) serves as the Rival in Pokémon Ruby, Sapphire and Emerald, should the player choose to play as the female character. He is also the male choice in the games, but Brendan is never among the default names for the character.
The Generation III games broke from the tradition of naming characters as their respective game colors, such as Red in the Generation I and Generation II games. As such, Brendan's counterpart is Ruby in the Pokémon Special manga. Rarudo, one of Brendan's default Japanese names, is used in the manga Pocket Monsters Emerald: Challenge!! Battle Frontier.
In the anime
Brendan's only anime appearances are small cameos in the opening of Jirachi: Wish Maker and Pokémon Ranger and the Temple of the Sea. Like in the games, he has the starter Pokémon that weakens May's. It is unknown if his relatives are the same as that of the games, where, as May is Norman's daughter (as the player is), Brendan would be Professor Birch's son.
In the games
