Pighead

Pighead is the main antagonist of Saw the video game. Pighead is a masked and silent character, never speaking a word in the game (wheather he, or she' can,t speek or if this was done simply to keep others from learning their identity and to raise mystery is unknown). Pighead is apperently an apprentace of Jigsaw (Saw), the villain of the saw franchise, he has had two other apprentancess inthe series: Amanda Young and [Mark Hoffman, but neither one apear to be the character. Pighead kidnaps the games hero, David Tapp and has a key put in his chest before placing him in one of Jigsaws reverse bear traps, after the man is shot by zep hindell (another one of the saw victims) and left injuried in the sewers near jigsaws lair in the first saw movie, where Jigsaw apperently discovered him. After Tapp escapes the trap he learns that Jigsaw had taken him to an abbandoned assylem where he has everal other victims locked away in, it is also leant that the key that was put in his chest can be used to oppen the various traps in which the other vitims are encased, hench the other victims are given weapons to kill Tapp with so they can free themselves with the key they plan to cut out of his chest. Pighead appears throuought the game to kidnap you and force you into traps, he also appears once to fake the kidnapping of amanda, who has joined the game to help test Tapp, now that her part is complete they need to get ther out of their without Tapp learning she's an apprentace of Jigsaw. At the end of the game Pighead becomes it's only boss, Jigsaw informs Tapp that Pighead is disobbeying his orders, planning on killing Tap even though he had finished his tests, Pighead arrives and tries to kill Tap, but Tapp eventually electrocutes him to death, an act that Jigsaw calls murder.

Identity
Pighead,s identity is never revealed in the game, he never speaks and his face is never seen, even after he is killed Tapp does not bother to remove his pig mask, some think it could be Hoffman whom they think in that case survived the electrocution and merly faked his death, however it is unlikely that anyone could survive such a large shock of electricity, so it is unlikely that it is hoffman, wheather, this persion is likely a never before seen third apprentace of Jigsaw, it is unlikely that we will ever learn who he (or she) was.
