Peace Walker (Basilisk)

Basilisk, officially called Peace Walker, and once referred to as Butterfly, was an AI weapon developed by the Peace Sentinels. It bears a resemblance to a Metal Gear because the designs were in part based off of Soviet Blueprints of a bipedal locomotive weapon stolen by Huey Emmerich. Although technically bipedal, Basilisk's primary mode of transportation is more similar to a quadrupedic machine. It has two AIs: One is a Reptile Pod, whileas the other is the Mammal Pod, deliberately more advanced than the Reptile Pod in order to give it the capacity to launch a retalitory nuclear strike if it verifies the strike as an imminate threat. Unlike Metal Gears, however, Basilisk is completely incapable of launching a Nuclear Weapon by itself, only launching out of self defense, as part of the theory of Deterrance. However, it can be tricked into launching a Nuclear Weapon into a country that never even launched at all through false data. It also transmits the false data to third parties, as revealed by Coldman when he initiated the launch code with his dying breath. Its armanants, aside from the nuclear launcher, include an immobilization ray, flamethrowers, regular missiles, mole missiles, and various other weapons.
