is only in Metal Gear Solid 4 that the player is finally able to canonically defeat Ocelot (albeit as Liquid Ocelot). Before the final battle, Ocelot remarks that he and Snake still had "a score to settle." While potentially referencing Snake and Liquid's rivalry, this statement is also ironically true in regards to Ocelot's previous battles with both Naked Snake and Solid Snake.

Metal Gear Solid: Peace Walker

Metal Gear Solid: Peace Walker is the first Metal Gear Solid title not to feature Ocelot. He is indirectly mentioned in one of EVA's tapes to Big Boss, as the reason behind the assassination of The Sorrow, Ocelot's father, by The Boss, Ocelot's mother, in 1962. He is also indirectly mentioned in Strangelove's tape to Big Boss, regarding The Boss's confession toStrangelove of when she discovered that was pregnant with her child in the middle of a mission. He also was given a subtle reference in the HD version of the game, where his catchphrase, "You're pretty good", was the name of an achievement/trophy issued to players who successfully managed to shoot a soldier in the rear end and instantly down them.

Super Smash Bros. series

In Super Smash Bros. Brawl, during Solid Snake's in-game Codec conversation with Mei Ling regarding Pikachu, Ocelot is briefly mentioned as Snake recounts the famous torture sequence in Metal Gear Solid, implying that the lethality of Pikachu's electric-based attacks pales in comparison to the interrogation he endured at the hands of Ocelot. He also appeared as a sticker, which can only be worn by Ganondorf.
