Doctor Phillip (t'phil) Kerridan

A scientist aboard USS Aerostar, Phillip Kerridan presented himself continually as a thorn in the side of Captain Andy Baxter. He assisted Lt. Larkin with the creation of a subneutrino transmitter, which was used to send Andy Baxter's consciousness across the galaxy back to the Alpha Quadrant ("Cat-Astrophe" [VEX]). When that didn't work out, Kerridan went on to help fix a jumbled of cris-crossed minds when the Aerostar visited 20th century Earth later that year ("Out of Time" [VEX]). After repeated sabotage attempts aboard the Aerostar, Kerridan was found to be an undercover Romulan spy from the Tal Shiar known as T'Phil ("Turned Inside-Out" [VEX]). Afterwards, after crew returned to the Alpha Quadrant, Captain Baxter fed him to a hungry Flarn and blew him up along with the rest of the evacuated Aerostar ("Confrontations" [VEX])..
