From Bulbapedia, the community-driven Pokémon encyclopedia.
Vitzo (Japanese: ボイド Boyd) is the manager of actor Brad Van Darn and a character of the day who appeared in The Screen Actor's Guilt.
Vitzo did not like Brad's companion Pokémon Smoochum, namely because he feared it would ruin Brad's action star persona and subsequently put himself out of a job. He hoped Brad would get rid of Smoochum on his own, but he wouldn't, even in spite of his manipulation tactics and the threats to Brad's career prospects. As a result, Vitzo appointed two police officers, who were really Jessie and James in disguise, to get rid of her. In reality, Team Rocket planned to keep Smoochum for themselves.
Brad managed to save Smoochum in front of an audience of his fans, after which he confessed that Smoochum was his best friend. Contradicting Vitzo's concerns, Brad's fans turned out to love Smoochum, and Vitzo then tried to claim Brad owning Smoochum was his idea. Later, he let Smoochum star in movies alongside Brad.
