The ADR-01: Jeri Type is a major antagonist in the anime series Digimon Tamers. It is a spy type agent that is at the same time a separate being and a part of the D-Reaper's artificial intelligence, based and modeled after Jeri Kato, Takato Matsuda's friend. It was created after the program kidnapped Jeri and used her negative energy and sorrow for Leomon's death to feed itself and follow the Tamers into the Real World. As the name implies, it is the first agent created by the D-Reaper.Like Jeri and the D-Reaper, the ADR-01 was voiced by Yoko Asada in the Japanese version, and Bridget Hoffman in the English version.
