. "The AI weapons' main development was headed by Huey Emmerich, while Strangelove created Peace Walker's advanced decision-making AI system, known as the Mammal Pod. Peace Walker was the final culmination of AI research gathered during the development of Pupa, Chysalis and Cocoon. As such, the names given to the three prototypes all referred to the transformation stage of a butterfly's life cycle, while Peace Walker itself was often referred to as \"Butterfly,\" and its Mammal Pod, the \"Imago.\" In addition, other than the AI pod(s), the heads of the AI weapons themselves also functioned as a core to their main weapons, which would result in usage on other unmanned weapons should they be salvaged."@en . .

The AIs belonging to the AI weapons for the Peace Walker project's speech synthesis system repeated pre-set messages that would play depending on the situation. Peace Walker was the only one of the AI weapons from this project, as well as the AI weapons overall (counting ZEKE) that was capable of self-generated speech."@en . . . . .
