God is the final boss of Silent Hill 3, encountered at the end of the chapel. Heather Mason must kill God and put an end to Her religion, the Order, in order to save the world.
God grew in Heather Mason's womb, due to Claudia Wolf's plotting and Valtiel's (the attendant of God) constant vigil. Claudia also torments Heather throughout the game, letting God feed off of her anger, hatred and despair, believing that a deity who is familiar with such emotions would be kinder and more empathetic than one born of happiness. The birth of God ensures the death of the host mother which is one reason why Heather is reluctant to give birth to God.
God appears as a huge hideous half-skeletal being whose face resembles a porcelain mask with the likeness of Alessa Gillespie: Heather's true identity and Claudia's childhood friend. This is likely because the manifestation of God, as previously established in the first Silent Hill, takes on the appearance of what the host, or ritual performer, perceives God to look like. She possesses Alessa's dark disheveled hair.
Due to God's unnatural and hasty birth, as well as the hate and anger in Heather's heart, She is twisted and malformed, with Her legs lacking flesh and ending at the knees. Her spine and pelvis are visible.
