In Pokémon Black and White, Kudari is one of the leaders of the Battle Subway alongside Nobori. He first appeared at the end of BW045 with Nobori when they detected Team Rocket's interference with the track switches. Later in BW046, the pair searched for the source of the disruptions and saw two mysterious figures before they vanished into shadows. In BW047 and BW048, Kudari and his brother were riding a subway that stopped, where they met Ash, Cilan, and Iris. They reappeared in BW051 to have a tag battle against Ash and Cilan. Nobori is referred to as "big brother" by Kudari, indicating that he is the older twin.
