Ar'jykke

Ar'jykke Grssh'hgnkh (known by its human shipmates as Diamondhead) is a Tholian, and a member of the USS Admonitor's civilian crew.

History
Not much is known about Ar'jykke. According to his own testimony, he was captured and placed in the research laboratories on Typhon III, and underwent grotesque biochemical weapons testing from Federation scientists (despite the fact that Typhon III was a slave colony and never had any research labs). According to his testimony, the break-out caused him to be released. Remarkably so, he and his containment chamber were beamed into the cargo hold of the USS Admonitor without being detected by any of the crew and over the past one-and-a-half years, remained alive yet undetected in the cargo bay.
