Doctor Zager (Japanese: ゼーゲル博士 Professor Seger) is a scientist for Team Rocket who was assigned to study and analyze the Meteorite that crashed in Unova . As per Pierce's instructions, Jessie, James and Meowth dropped off the Meteonite fragment they stole from the Nacrene Museum when they arrived at MT37 KS816 in Nacrene City where Doctor Zager and Pierce were waiting for them. Doctor Zager took the fragment and with the assistance of his equipment, he was able to determine that the fragment was genuine and confirmed it contained materials not found anywhere on the planet.
After the Meteonite quest, Zager became a commander to Jessie, James and Meowth creating such machines as the Roggenrolla Cannon and the Ghost Train.
Zager also restored a Tirtouga which made the time warp in Twist Mountain open. Zager commanded Jessie, James, and Meowth to capture ancient Pokémon.
