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.
He did not like Brad's companion Pokémon Smoochum, namely because he feared it would ruin Brad's action star persona and thus put him out of a job. He was hoping Brad would get rid of Smoochum on his own, but he wouldn't. His manipulation tactics and threats to Brad's career prospects failed. That was when he told two police officers, who were really Team Rocket in disguise, to get rid of her. Team Rocket planned to keep Smoochum for themselves.
Brad managed to save Smoochum in front of an audience of his fans, where he confessed that Smoochum was his best friend. Vitzo believed it was all over for Brad's career and hid his head in shame. However, Brad's fans loved Smoochum. Vitzo then tried to play it off as Smoochum was all his idea, though Ash and his friends shook their heads at Vitzo's glaring self-interest. Later, he even let Smoochum star in movies alongside Brad.
