Killer T Cell (キラーT細胞) is a minor character in Cells at Work!

He is a white blood cell, specifically a  

Cytotoxic T Lymphocyte (Cytotoxic Thymocyte) that works under the Killer T Division. He is tasked to kill any foreign entities and cells that are damaged or infected.

He becomes a Memory T Cell when fighting the same antigen (Cancer Cell).

He is later shown with a Memory T Cell hat.

Personality
Killer T Cell is loud, obnoxious, and quick-tempered, resulting in rivalries with many cells. He also despises it when a non-white blood cell forms a friendship or relationship with one of his kind.

History
As an immature thymocyte he went through training at Thymus school, where apprentice cells like himself learn to become Mature Thymocytes. Although in the beginning he was scrawny and weak, he never gave up. There he also met Helper T Cell. They end up forming a grudging friendship.

Abilities
Killer T Cells are strong cells who play an important role; they kill cancers cells, infected cells as such.
 * Overall Abilities: Like all killer T cells, he is tough and masculine. Possessing heightened strength, he can easily terminate threats with one strike and break walls of tissue.


 * Martial Arts Proficiency: He can wield other weapons like a knife, but free hand is his preferred choice. His attacks are packed with a lot of strength, thus one punch can kill threats like influenza infected cells.
 * T Cell Perforin Canon Punch: A legendary killer T move that only can be unleashed when one's desire to protect the body is at its limits. He was able to utilize the special technique once during the final Cancer Cell arc. It is unknown whether he will be able to use the technique again in the future.
 * Memory T Cell: Killer T Cell can take the role of a Memory T Cell when fighting an enemy he has fought before, signifying that he is familiar with most of the enemy’s moves and is using that knowledge in combat.

Trivia

 * Cancer cell called his attack by a pun --.
 * Natural killer cells and killer T cells resemble brothers-in-arm because of their complementary roles for each other. This explains the close yet competitive relationship between NK Cell and Killer T Cell in the series.
