Killer T Cell

Killer T Cell is loud, obnoxious, and quick-tempered, resulting in rivalries with many cells and is prone to being violent. He also despises it when a non-white blood cell forms a friendship or relationship with one of his kind and doesn't tolerate any failures from anyone under him.

Killer T Cell is a tall, masculine cell with tan skin, blond hair, and gold eyes. He wears the killer T cell non-bulletproof vest uniform.

They have the tendency to be loud, rude and rambunctious, though still have an innate nature to care for the body. Like other immune cells, non-immune cells tend to distance themselves from them due to their violent lifestyles. Killer T cells seem to have a code of not being involved with other cells as it will make their jobs of terminating infected cells harder (as expressed by Killer T Cell).

As immature thymocytes, they are raised and trained in the thymus gland, it is said that only 2% of the trainees last long enough to become matured T cells. Here, their ability to distinguish between normal and infected cells are tested. They are trained by Dendritic Cells, Macrophages and Monocytes.

They are Naive T cells until they encounter their first virus, or until they are activated by outside help, which allows them to be an Effector T Cell for a short period of time against a specific enemy. As Killer T Cells, any member may play the role of a Memory T Cell if they have encountered the same strand of pathogen before.

All Killer T cells wear the same uniform. They wear black buttoned shirts with two front pockets and black pants along with a belt. They also wear black shoes and a cap with "KILL" printed on it. When a Killer T cell becomes a memory T cell during an invasion, the cap will be switched into another cap with "MEMORY" to avoid confusion between the two cells. Naive T cells also shares the same uniform but they wear caps with "NAIVE" instead.
