Experiment 061 was the 61st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to upgrade Jumba's technology by bringing better technology from the future.
061 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
At the unknown point, Anachronator was activated, captured and named Anachronator.
The first 624 experiments, including Anachronator, were round up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
Anachronator participated in the following battle between the experiments and the Leroy clones.
The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song Aloha Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
Anachronator is a green experiment with very long legs, short arms, big ears with yellow insides, two antennae, a stubby tail, yellow spots on his stomach and back spots and yellow markings on his back.
