Description
Purple Rat, also referred to as Purple Mouse, is a Destructoid that appears in the Android Kikaider television series. It is the twenty-first Destructoid created by the evil organization DARK under the direction of its leader, Professor Gill. Its Japanese name, Murasaki Nezumi, literally translates to purple mouse, and consistent with the series' pattern, it is the purple animal-themed member of the Destructoid lineup, in this case based on a rat or mouse.

The character appears in the twenty-first episode, an installment titled Brutality! Purple Rat's Poison Fangs. In that episode, Purple Rat infiltrates a laboratory dedicated to the study of communicable diseases with the goal of producing a new plague for DARK. This mission sets it apart from many of the more straightforwardly combative Destructoids, since its objective is biological warfare and the creation of a devastating disease rather than a direct physical confrontation alone.

In terms of personality, Purple Rat is presented as an obedient instrument of DARK rather than an individual with a developed inner life. Like other Destructoids, it exists to carry out Professor Gill's orders and has no independent moral compass. Its actions reflect the cruelty of its creators, as it is willing to endanger civilians and target a medical research facility to advance DARK's plans for conquest. It behaves with aggression and determination once engaged in combat, but its characterization remains that of a specialized weapon rather than a thinking antagonist.

Purple Rat's role in the story is that of a one-episode threat. It is dispatched by Professor Gill to complete a sabotage mission, and its scheme is uncovered during the course of the episode, bringing it into direct conflict with the hero Kikaider and his allies. Its defeat at Kikaider's hands prevents DARK from obtaining the plague it was sent to create, and the creature does not appear again after that encounter.

Its key relationships are defined entirely by its allegiance to DARK. It is subordinate to Professor Gill, who sends it into the field, and it operates alone rather than alongside other Destructoids. Its principal adversarial relationship is with Kikaider, the android who opposes DARK's operations and ultimately destroys it. There is no indication of any personal bond or loyalty beyond its programming.

Purple Rat undergoes no character development. It is introduced, carries out its mission, and is destroyed within a single episode, which is typical of the Destructoid model in the series, where defeated units are replaced by new models in later installments.

Its notable abilities are centered on a combination of physical strength and built-in weaponry. Large horns grow from its face, and these horns are powerful enough to break through concrete walls. It is also equipped with a number of named weapons: the Electroshock Rat Rockets, a pair of cone-like rockets set into its nose; the Rat Photo-bomb Flash, a pair of lamps located in its neck; the Rat Guillotine, a tentacle that serves as its right arm; and the DARK Germ Gas, a toxic white mist that it releases from its mouth. In addition, it can fire a projectile known as the Lightning Mouse Firework, which produces sparks when launched. The title of its debut episode draws attention to its poison fangs, indicating that its bite carries venom as well.
