Kudari is one of the leaders of the Battle Subway in Pokémon Black and White, along with Nobori. Kudari made his debut appearance at the end of BW045 along with Nobori where they detected Team Rocket's tampering with the track switches. In BW046 the pair went in search of what or who was causing these disturbances and they caught a glimpse of two figures before they disappeared into the shadows. In BW047 and BW048, Kudari and his brother met Ash, Cilan, and Iris as the subway they were riding had stopped. Kudari and his brother reappeared in BW051, where they had a tag battle against Ash and Cilan. Kudari refers to Nobori as "big brother" indicating that he is the younger of the twins.
