[edit] Background

Python is a twisted, depraved character who is obsessed with matching Big Boss and being his complete equal on the battlefield. He and Big Boss fought in Vietnam together, and he was considered by Big Boss to be the one person he could count on in battle. However sometime during a secret mission in Vietnam, Python received a severe injury which cost him the ability to regulate his body temperature, and as a result, Big Boss presumed him to be dead. Without intense medical care, Python would overheat to the point where he would eventually die. This eventually resulted in the need for surgery where he was fitted with a specially designed cooling suit filled with liquid nitrogen, complete with metal shunts installed in his skull to relieve himself of excess heat.

Because of this, he is able to freeze objects that are close to him by flushing the liquid nitrogen inside of his suit out into the environment, though by doing so he loses some of the cooling agent, making him heat up slightly. He is also a superb marksman, especially with assault rifles and due to the nature of his suit he is difficult to engage in hand-to-hand combat. Similar to other soldiers such as Null and Raiden he has a barcode imprinted on the back of his neck.

During the San Hyeronimo Incident, Python once again came face to face with Big Boss, but this time as his enemy. The two fought against each other, but Big Boss eventually gained the upper hand, and defeated him. Snake, with no intention of killing an old friend, instead requested that Python joined him in defeating the other members of FOX and helping to clear his name. Python accepted and helped him in his mission. Python is equipped with LNG (Liquid Nitrogen Grenades) that can be used to launch his freezing agent to long distance enemies doing damage as well as freezing their weapons.

[edit] Trivia

• If the player kills Python during the boss battle instead of acquiring a "stamina kill", Python dies and doesn't join Big Boss' team.
• Python resembles horror film villain Pinhead from the Hellraiser series due to the pins protruding from his head.
• Most likely prior to his service in the military, he was a quarterback and a scout according to info in Portable Ops.
