Age: Late 40s

Thomas Richards is a character and an antagonist first encountered in Issue 13 of Image Comics' The Walking Dead. He is a psychopath convict, who survived the outbreak trapped in the prison cafeteria, along with Axel, Dexter, and Andrew. He served as the primary antagonist of Volume 3: Safety Behind Bars.

Even though he died quite soon after his introduction, Thomas' role was partly significant. As a minor antagonist to the survivors, he exposed the biggest threat to stability in a zombie apocalypse: fellow survivors. The survivors had not encountered many violent or extremely dangerous humans before their arrival at The Prison, and as such, were unprepared for the deceitfully insane but crafty Thomas impressed upon the group. Although his personality was hidden due to his quiet nature, he was soon exposed as a bloodthirsty psychopath, as shown from his horrific obsession with decapitating people, evident by his murders of the Greene twins and attempted murder of Andrea and Patricia. Thomas' logic also seemed to be hypocritical, as he berated Andrea's use of strong language but then proceeded to shout graphic profanities at her, both whilst trying to kill her. Before they realized he was a psychopath, he seemed to be a quiet person, who was described as "nerdy" as well as nice, as he helped the women with their laundry and such.

It's VERY important that he doesn't come across as creepy/disturbing when he's not murdering, as to not telegraph his true intentions.

He COULD have a calm/quiet voice, COULD have a friendly voice and/or COULD have a southern accent, but don't let these limit your vocal choices at all.
