Liquid Ocelot

He placed genetic engineering scientist Naomi Hunter under house arrest, forcing her to access the Sons of the Patriots System.

---

Using Big Boss's genetic code to enter the Patriots' AI network, Liquid Ocelot succeeded in taking over the Sons of the Patriots. Renaming it the Guns of the Patriots, he used it to disable every gun and weapon in the world. He then stole the Arsenal Gear-class battleship from the Patriots, and outfitted it with Metal Gear REX's rail gun. He then attempted to use a nuclear warhead launched into orbit from the rail gun to destroy the Patriots' core AI, "JD", in space.
