Big Boss has Huey Emmerich create Metal Gear ZEKE as a weapon to defend his interests, with no desire to use offensively. After Big Boss killed Gálvez out of self-defense, Paz pilots ZEKE to launch a nuclear strike on the Eastern Coast of the United States as part of an insurance policy if Big Boss refused to obey Cipher. After hearing the ultimatum, Big Boss refuses and fights ZEKE in order to stop Paz. He is victorious, but ZEKE is heavily damaged and Paz is ejected into the Caribbean Sea. After ZEKE's destruction, Kaz tells Big Boss of being aware of the plot from the beginning, and used it to spur MSF's growth. Big Boss and Kaz realize they'll no longer be able to be away from the outside world unless they reveal their true nature. Big Boss rejects this idea, stating that his "life shall be different from The Boss'". After this conversation, Big Boss gives a speech to the MSF soldiers, telling them that if the times demand it, they will be vigilantes, criminals and terrorists, but they will be the ones to choose their battles and their causes, not governments. Metal Gear Solid V Big Boss plays a central role in Metal Gear Solid V: Ground Zeroes and Metal Gear Solid V: The Phantom Pain. He is on a mission to rescue a child soldier and Pacifica Ocean from an American black site on Cuban soil; Big Boss believes that Pacifica can be converted to MSF's cause. His rescue is successful and the medic found a bomb implanted inside Pacifica who is sacrificed to save everyone from another bomb which causes an explosive concussion wave which causes the helicopter to crash into the Caribbean Sea as MSF is destroyed by the invading XOF paramilitary force led by Skull Face. Big Boss comes out of his coma and poses as "Ishmael", a patient in the hospital where Venom Snake is being treated. He aids in an escape when the hospital is attacked by Skull Face's forces. While his mental doppelganger ventures into Soviet-controlled Afghanistan using the new mercenary force Diamond Dogs made from MSF's remaining forces, Big Boss stays behind the scenes to develop the true version of Outer Heaven.
