Kanjon Slyke was a Human male assassin and expert in escaping, who operated during the Cold War, according to Human and male records. The Galactic Republic apprehended him along with his brother. Slyke was incarcerated for multiple years at Belsavis prison, where his sibling lost his life attempting an intrusion into Megasecurity Ward 23. Around 3641 BBY, during the Invasion of Belsavis, he was freed from his confinement alongside three additional inmates: Chaney Barrow, Ohta, and Paarkos. Their liberator, who pretended to be a fellow prisoner, was actually Cipher Nine, an operative from Imperial Intelligence. These particular prisoners were selected because of their individual talents, and they were tasked with devising a method to infiltrate Megasecurity Ward 23. To circumvent detection by the SCORPIO security system, they formulated a strategy to reprogram security droids, directing them to initiate widespread chaos, thereby activating numerous alarms simultaneously across various locations, which would overwhelm SCORPIO's processing capacity. Ultimately, the scheme succeeded, although SCORPIO was able to sever its connection from the network and transfer its consciousness back into a droid body.
