During the Galactic Civil War, a hive of aggressive klikniks inhabited the Temple of the Blueleaf Cluster. After the Battle of Yavin, Doctor Maldien conducted illegal and highly dangerous bioengineering experiments in a laboratory on Corellia to create very aggressive and intelligent creatures. This included engineered klikniks.
Klikniks appeared in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game developed by Sony and published by LucasArts, prior to its closure on December 15, 2011.
