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, 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 for them.
