Piggsy is an antagonist in the 2003 horror game Manhunt, released by Rockstar Games. Piggsy is a deranged mass murderer who uses a severed pig's head as a mask and has lost all connection with reality and is completely inhuman in behavior.
GTA San Andreas
Piggsy's existence in San Andreas was sparked by various online rumors during the release of the game, but it gained popularity when YouTube myth hunter DarthDementous posted a video about the Shady Creeks Creature in 2008. In the video, a short figure resembling Piggsy was seen in a freeze frame shot near the end of the investigation. This video prompted a large discussion within the GTA community about the existence of a pig-like creature in GTA San Andreas, thus the birth of a new myth called Piggsy. Piggsy has been reportedly sighted in GTA San Andreas around Mount Chiliad and in Shady Creeks. Piggsy is said to carry a Chainsaw around, to maim and kill his victims.
There are various in-game clues that support Piggsy's existence in GTA San Andreas. First of all, both Manhunt and GTA San Andreas were released by Rockstar Games. There is also an action figure of Piggsy sold in San Fierro at Zero's RC Shop. The small three-dimensional action figure has been proven to exist in the game files, so many believe a larger interactive version exists too. Of course, the 3D action figures have bendable and rotatable parts which most toys like action figures and dolls have. The action figure located in Zero's RC shop serves as an Easter egg to reference the Manhunt video game. Unfortunately, most of the online photos or videos that supposedly show Piggsy are the result of mods. A balding redneck pedestrian that is believed to be Leatherface has dialogue in which he says "Watch it, piggy." The pedestrians connotations to another chainsaw killer and the reference to Pigs make it likely that this is evidence of Piggsy's existence within the game. Many early internet rumors have Piggsy and Leatherface feuding.
Nevertheless, this was one of the largest and most popular myths in GTA San Andreas.
Some bizarre pig grunts can be heard in Vice City Alleys with players theorizing that it could be a reference to Piggsy, with some claiming that the Chainsaw Killer, also known as the Apartment 3C Killer, is in fact Piggsy himself. Despite being released after Vice City, Rockstar is known for hinting future games prior to their release so this is possible. Further veracity is yet to be revealed.
Grand Theft Auto V
There is currently no conclusive evidence that Piggsy physically exists in Grand Theft Auto V. The closest possible evidence of Piggsy in-game is the bloody pig mask which can be purchased at the Vinewood Masks Shop on Vespucci Beach. This mask can only be purchased in GTA Online.
