This irate character was a belligerent male Rodian located within tower 214 on the planet Byblos. Possessing a strong aversion to droids, this Rodian may have unknowingly been involved in U-THR's plan to free Crimson from the clutches of the Imperial Customs agency. It's plausible that U-THR goaded the Rodian into pursuing him into the Imperial Custom's office as a distraction, thereby enabling Crimson to make their getaway.
Within the solitaire adventure Crimson Jailbreak, the reader is presented with the option of utilizing the irate Rodian to stage a diversion, representing one of several available paths. Alternatively, they could choose to reprogram a binary loadlifter.
