Trenix
Trenix was a Gesaurian mercenary who did jobs for the Sinestrans and the Syndicate, a group that he greatly feared. He gave evidence in the case against the Sinestrans, after which he was put into witness protection by the Lawkeepers of Pandrin V and given the alias of "Tony Reynolds". Living in 1978 London and wearing a DNA coder which disguised him as a human and curbed his bloodlust, he worked as a shopkeeper at Reynolds Hardware and befriended Ann Kelso.
Seen as a threat by the Syndicate, the Sinestrans were ordered to kill Trenix. Spandrin eventually located him and blocked his ability to contact the Lawkeepers with his encrypted microparticle multibank communicator using a warped field damper. He was assisted by the Fourth Doctor, Ann and Scott Neilson and once more requested an extraction team from the Lawkeepers without receiving an answer. Eventually, Trenix removed his DNA coder and allowed Spandrin to take his body, which was then destroyed by the Sinestrans. (AUDIO: The Sinestran Kill)
