Thot Phul
Thot Phul was a Breen officer as saw Reginald Bain as his nemesis. He first encountered the USS Anomaly when he was in command of the XAXRDAARD. At that time, the Anomaly was still called the Hermes 7, and it was on its way to deliver Cabral to his date with Jacinda. (‘’If I Only Had a Brain’’ [BG])
After learning that the Hermes was now the USS Anomaly and that the ship was heading to Breen for peace negotiations, Phul hired a holographic assassin to attempt to kill Reginald Bain. This failed, and Rosalyn Bain beat him up badly for trying it. Phul did not see his attacker, since she was cloaked at the time. (Mrs. Bain, You're Needed [BG])
When Thot Luss intended to take the Regularity to Earth and defect to the Federation, Phul had the XAXRDAARD pursue. He was pleased to learn that the Anomaly was also chasing the Regularity, and he planned to destroy both ships, avenging himself on Bain. He chased the Anomaly into DeanSpace. Unbeknownst to him, this was a trap, and the Anomaly was actually under the command of Commander Prosak when the two ships engaged in battle. Prosak beat Phul easily, destroying the XAXRDAARD. Phul and his crew were able to get to their escape pods and get out of DeanSpace. (Every Space You Take [BG])
