Working Joe 937, designation "Chuck", was a Seegson "Working Joe" synthetic that was active aboard Sevastopol in 2137. At some point after a Xenomorph Drone got aboard the station in 2137, Chuck reported to APOLLO, Sevastopol's mainframe, that the Colonial Marshal ability to contain the unrest was poor, and that "official reports" indicated that Waits had a drastically reduced force under his command. Chuck was also informed by APOLLO that Waits has been flagged as a person of interest by a Seegson executive mandate and was supposed to be watched closely. Chuck understood APOLLO's order and heads out to confront Clark, a civilian trespasser. Chuck managed to locate Clark and proceeded to strangle him to death. After dealing with Clark, Chuck reported back to APOLLO, only to encounter Waits. Chuck told Waits that he shouldn't be there, only for Waits to respond by shooting Chuck, destroying the synthetic.
