Introduction:

The Matrix media series largely consists of science fiction action movies, cartoons, and comic books. The series imagines a future in which the world that most people experience is actually a simulation made by sentient machines to control the human population while their heat and electrical activity serve as a source of energy. The world shown in the Matrix film series is one in which the majority of people are not aware that their reality is a computer simulation, or "Matrix." Action, philosophy, and transhumanism are all themes that are explored in the Matrix movies, comics, and other media.
