Pyramid Head is a false myth in Grand Theft Auto: San Andreas, Grand Theft Auto IV, and Grand Theft Auto V. Pyramid Head is a fictional character from the 2001 psychological horror video game Silent Hill 2. Pyramid Head is a tall creature with a man's body and a large pyramid-shaped like mask, which is his actual head, as his most distinguishable feature. Players believe that Pyramid Head can be found in the Grand Theft Auto universe.
Grand Theft Auto: San Andreas
The Pyramid Head is rumored to be found in Rodeo, Los Santos in a Creepy House. Because of its suspicious rust texture, it is hinted that the Pyramid Head lives there. Although various photos show Pyramid Head, most of them are mods so their existence is false.
Grand Theft Auto IV
Pyramid Head is a dangerous demonic humanoid that pursues Niko Bellic and Luis Lopez in a hunt for their lives throughout Liberty City. Pyramid Head has rarely been reported and is presumed as a false or made up myth. However, the popularity of his role in a machinima known as Silent Hell has led many people to insist that he exists in the GTA universe. There are various photos and videos online that apparently show proof of Pyramid Head, but most of them are just mods or hacks.
Grand Theft Auto V
Not many reports have been submitted about Pyramid Head. There has been a decent sized jump in the topic. Not much is known about him in GTA V, but he sure has been causing some commotion. As mentioned in the GTA IV section above, Pyramid Head is not a common report, for it is quite rare. Also, is is most likely determined that Pyramid Heads' behavior will be hostile toward players. Like the previous games, the possibility that Pyramid Head existing in the game are near nonexistent since acquiring rights to feature the character solely as an Easter Egg would require Rockstar to pay royalties to Konami (who own the Silent Hill franchise.)
