Crystallene, A.K.A. Experiment 618, is an illegal genetic experiment created by Jumba Jookiba. She is designed to turn things into precious stones. Her one true place is in a mine. Crystallene is voiced by Tara Strong.
618 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, 618 was activated, captured, tamed and named Crystallene.
The first 624 experiments, including Crystallene, were rounded 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.
It is unknown whether or not Crystallene 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Crystallene is a tall, bright purple koala-like experiment with long ears, a large nose, small eyes and a thin body. Her ears are always crossed, and she has blue markings on her forehead.
Crystallene has the ability to turn objects into precious stones (crystals, rubies, diamonds, and gems) by using her eyes or fingers.
- Crystallene's pod color is blue.
- Crystallene is described by the experiment computer screen as, "Experiment 618 Primary function: Crystallization".
