Trenix

Trenix was a Gesaurian mercenary.

Biography
Trenix was naturally aggressive and worked as a mercenary, doing 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. (AUDIO: The Sinestran Kill)
