Ocelot plays a minor role in the plot of Metal Gear Solid: Portable Ops and appears as a recruitable character in the game, his appearance unchanged from Snake Eater.
In 1970, during the San Hieronymo incident, Ocelot had become dissatisfied with the Philosophers bickering, which had pitted the CIA against the Pentagon for control of the Legacy. Ocelot eventually decided to assassinate the DCI and take control of the entire Legacy himself. From this, he hoped to hand the country over to "the Patriots", which will be founded from the Legacy. Ocelot broke his ties to the unknown benefactor, whom Gene refers to as "the Man with the same codename as Null," until this mysterious man introduced Les Enfants Terribles to him. Ocelot was intrigued and agreed to allow this man to join him in the Patriots, as long as Big Boss was allowed to join as well. Ocelot's request came true when the unknown benefactor, Major Zero, along with Ocelot, Big Boss, Sigint, Para-Medic, and eventually EVA form the Patriots. Their dream was to shape the world into one which The Boss envisioned, although Zero's vision greatly differed from Big Boss', which would eventually lead to their downfall.
Ocelot can join Naked Snake's squad if the player fulfills certain requirements. You can also unlock him by entering the password R.R.R.
