Robar

Robar was the engineer on a recently revamped solar yacht, the Tiger Moth. The ship was attacked during its shakedown cruise by Sontarans searching for a Rutan agent. Robar was the first of the crew to be killed by the Rutan stowaway, and his form was used by the creature to lure others to their deaths. (RP: Shakedown: Return of the Sontarans)
