The Anti-Shadow Suppression Weapon is a type of android that appears in the Persona series. They were constructed by the Kirijo Group as a part of their experiments on Shadows and were created to wield a Persona and do battle with the Shadows.
Appearances

Aigis is the only Anti-Shadow Suppression Weapon that appears in Persona 3. Shuji Ikutsuki states that Aigis is the only one left.

Metis appears as the sister unit of Aigis. It is later revealed that she isn't an Anti-Shadow weapon at all, but Aigis's emotions that she discarded after the death of the protagonist.
Persona 4 Arena
Aigis and Labrys are playable characters in Persona 4 Arena. It is revealed in Persona 4 Arena that the Anti-Shadow Suppression Weapons were created and tested on Yakushima, and were given "souls" by having a Plume of Dusk implanted within their personality modules. Due to lacking the technology to create a personality from scratch at the beginning of the project, the generations of Anti-Shadow Weapons prior to generation seven had their personalities based on the personality of a girl who allowed herself to be used in the experiments in order to be useful despite her illness.
In order to gather test data to develop later generations, the earlier generations of Anti-Shadow Suppression Weapons were made to fight not against Shadows, but against each other. After their destruction, the memories of the units are transferred to the surviving unit, a practice that would continue even after the later generations of Anti-Shadow Weapons moved on to fight against actual Shadows.
