|For the myth in GTA SA, see Pirates (GTA SA).|
Some players believe that some form of pirates may appear in Grand Theft Auto V, whether they're dead or alive. Regardless of age, no pirates have appeared in this game, or any other games for that matter. The only real evidence for their existence is the ability to use the knife underwater.
Aside from that, it's mostly speculation from the large map, the large Pacific Ocean, and sunken ships out in the ocean, and the existence of plenty of random encounters in the game. There is a similar theory that rival treasure hunters were originally going to be present in the game, potentially taking objects from wrecks before the players take them. Over the time, many players have developed various mods, including legendary ghost pirate ships in the game such as the Flying Dutchman.
