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])
Following this defeat, Phul was given command of the Patroller DRAAT, a significant downgrade from his previous ship, and sent to patrol a vast area of nothing. Phul wanted revenge on Bain, though, and ordered the ship into Federation space. After learning about the Hermes 5 debris on Carsullis, he took the DRAAT there hoping to catch Bain. He was able to obtain the Hermes 5's backup computer core, which the Carsullans were worshipping as an Oracle, as well as Lieutenant Shelly Marsden and Cole Anfibon, who were both on Carsullis to get the core. The Anomaly arrived, again under the command of Prosak, and while Phul and Prosak exchanged demands and threats, Marsden and Anfibon were able to set off explosives, severely damaging the DRAAT, and escape. Lieutenant Commander Tovar finished the Breen ship off with a torpedo volley and beamed the Hermes 5 computer core back to the Anomaly. Phul and his crew abandoned ship before the DRAAT exploded.

Phul was too humiliated to return to Breen space and went to drown his sorrows in a bar in the hinterlands away from the Breen or the Federation. He was beamed away from there by the members of FOBBER, who recruited him to join their revenge plot against Bain. (The Bain Of Our Existence [BG])
