Zreeg

Constable Zreeg was a Wrarth Warrior of the Star Council police force sent with Sergeant Zogroth in pursuit of Beep the Meep.

According to one account, they both arrived on Earth circa the 1980s and, with the Fourth Doctor's help, took Beep into custody. (COMIC: Doctor Who and the Star Beast)

Another account suggests they instead arrived in 2023 and were killed after explaining Beep's true nature to the Fourteenth Doctor. (TV: )
