Killer T Cells operating in a mission.
Killer T Division is one of the immune forces in the body that is made out of T cells. They are white blood cells that are adaptive to the situation. In a human body, roughly less than 30% are T cells.
They follow orders from other T cells, namely Helper T Cell and Regulatory T Cell, and live in lymphocyte ducts that exist within the lymphatic system. They specialize in terminating infected cells, but not bacteria, and are only dispatched when there is a demand for their assistance.
Nature
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.
Uniform
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.
