From Bulbapedia, the community-driven Pokémon encyclopedia.
O (Japanese: オウ Ō) is a one-time character who appeared in To Thine Own Pokémon Be True!.
He is the champion of the Pokémon Ping Pong Tournament and also has a Ping Pong Training Center in Vermilion City. He is well-known for being an expert Ping Pong player.
After seeing Dawn's Ambipom's talent for Ping Pong, he invited her to train in his Ping Pong Center. After the tournament, Dawn gave Ambipom a choice- Pokémon Contests or Ping Pong. After much contemplation, Ambipom chose ping pong and left with O.

|| Ambipom ♀
- Main article: Dawn's Ambipom
Ambipom had a natural talent for Pokémon Ping Pong and was noticed by O during the Pokémon Ping Pong Tournament. After assuming they were regular players, O couldn't believe they were beginners and during the tournament watched Ambipom closely. Even though Dawn was an average player, Ambipom helped her through to the semi-finals where they were eliminated by O and Shiftry. Afterwards O offered Ambipom a place at his Ping Pong Training Center in Vermilion City which she accepted later with Dawn's permission.
