Thomas, better known as "10K" or affectionately referred to as Tommy by Cassandra, is a main character and a survivor of the outbreak in Z Nation. He is a member of the Westward-Bound Survivor Group.


In 10K's brief story line, he lived alone with his father in a national park. He was taught how to fish, shoot and take care of himself. They didn't have electricity or internet. When the zombie apocalypse came, 10K knew how to survive better than most at his age. He first revealed his nickname to Doc in "Fracking Zombies", and that after ten thousand kills, that he would go by a self-given name, "Jeff." His real name was revealed in the Season 1 finale Doctor of the Dead to be named Thomas. Cassandra calls him Tommy twice during the episode, almost in rapid succession; Murphy calls him Thomas as well, in Season 3 Episode 10 "They Grow Up So Quickly". 10K was on his way home from fishing when the apocalypse started. He was running for his life from an undead park ranger and several attackers when he hit his head on a tree. His father found him unconscious and proceeded to kill zombies in order to save him. 10K got his rifle from the dead zombie his father killed to save him, and then the two ran. Later his father was injured and 10K was forced to give him mercy, making a promise to him that he would stay strong and fight.


10K is rather quiet and observant. His real name is Thomas, or "Tommy" to his family. His first-line weapon would be his sniper rifle, with a slingshot being his secondary (as well as melee) weapon. He enjoys killing zombies; his goal is to kill ten thousand of them (hence his self-given nickname), and he is already over one-thousand kills by his first appearance. In the beginning, he was alone and seemed to like it. However, by the end, he considers the survival group his family and would do anything to protect them. This shows during season 4 when with the other followed Warren even though none of them knew what was going on.

As the settlement is overrun by zombies, he saves Brittany's father by giving mercy to a zombie that is closely following him.

10K manages to survive his plunge into the Spokane rapids, but once he makes it back to shore, with the bag of the original vaccine, aka 'Murphy's medicine, it's just one crisis after another.

Red helps 10K traverse these badlands, and it's a good thing, too: there's some sort of new menace that's tracking our hero, something that appears to be a pack of wolves but different. 10K is able to snag a motorbike and tries to get away from the area but ends up getting caught by a man and a woman who steals the bike, take the bag with the vaccines and chains 10K to a car. When 10K wakes up he doesn't have any weapons so he uses car parts to kill the zombies that are trying to attack him. Eventually, Will shoos off the remaining zombies, thanks to the powers given to him by Murphy's bite, and takes 10K prisoner as they follow the bike tracks to the bandits and, hopefully, the stolen bag of Murphy's medicine. Then they find the motorbike and 10K ends up making a run for it, he ends up faking his death by making it look like he was attacked by whatever was chasing them in the woods. He then hears the cries of 5K and he rushes to help, he ends up killing all of the Z's and turned over 5K's body but it ends up being the woman bandit and she had turned. He pikes her, takes the bag of vaccines and runs off, he makes it to the street and looks at the Spokane, Washington sign and falls on the ground. He takes out one of the vaccines and injects it into his leg, and ends up seeing Red and 5K in some hallucination of the afterworld/limbo.

The nurse had scheduled a lobotomy for 10K and proceeds to try and do the procedure because 10K keeps seizing and foaming at the mouth. Doc and one of the patients made a run into the Z-ward to try and get some medication for 10K and the rest of the patients as well. Doc makes it back just in time to stop her from even starting the procedure and tells her that he takes full responsibility for the patient (10K) and she leaves the room to check on the other patients.
