is a character introduced in the 2006 role-playing game Shin Megami Tensei: Persona 3 by Atlus. She is an android created by the Kirijo Group, and the last surviving model of their experimental anti-Shadow weapon. Besides possessing a wide variety of high-tech weapons, from machine guns and rocket launchers to long-range guns and "rocket punches," Aigis also has access to the power of Persona she uses alongside the main cast to defeat the Shadows attacking mankind. Across the game, Aigis starts showing human-like traits and it is revealed the reason for her attachment to the game's protagonist whom she seeks to be safe.
Aigis was created by Shigenori Soejima who despite being bothered by her inclusion in the game as a result of being android, came to find her design one of his favorites due to the amount of freedom he was provided in creating her. Aigis is voiced by Maaya Sakamoto in Japanese and Karen Strassman in English. Critical reception to the character has ranged from mixed to positive with criticism aimed to Strassman's voice work and praise at her character development.
