Seti (or simply known as Pharaoh) is the minor character but is the true main antagonist from The Prince of Egypt.
Pharaoh Seti I may appear to be a wise and kind old man, but his cruelty brews just beneath the surface. He is vicious and cold, having every Hebrew baby boy killed because they were "only slaves". However, he had done it out of fear that the Hebrews might one day rise in number and power to start a rebellion that will threaten his legacy.
Role in Film
Pharaoh Seti I is the ruler of Egypt alongside his queen, Tuya. He is the father of Rameses II and the adoptive father of Moses. At the beginning of the film, he ordered his Egyptian soldiers to kill every male Hebrew baby out of fear that the Hebrews would grow in number and rebel against him. Later, he reprimands Moses and Rameses after a temple is destroyed. He is especially hard on Rameses, who he feels he must prepare for the throne. Moses appeals to Seti's better nature and promises him that Rameses sought only his approval, and would succeed if he only had the opportunity.
Seti later appears at the feast where he appoints Rameses as Prince Regent, by Moses's recommendation. Moses suggests Hotep and Huy pay tribute to their new Prince Regent with a gift. They bring out Tzipporah, a Midian girl captured as a concubine for Rameses, who eagerly gives her to Moses because she is too spirited. After Moses struggles to restrain Tzipporah, he jokingly "lets her go" into a small pool behind her. Seti is indifferent to this display, but his wife is ashamed of the behavior.
After Moses is told by Miriam that he is a Hebrew, he has a nightmare of his people being killed. As Moses searches for answers through historical etchings throughout the palace, he finally finds a mosaic of Seti ordering the massacre of infants. Pharaoh finds a devastated Moses and reveals to him that he had the Hebrew infants killed to keep their population in check and prevent any rebellion against him. He attempts to comfort Moses with a hug and justify his behavior, but when Seti tells Moses that the children were "only slaves", Moses backs away from him in disgust. Seti dies some point after Moses escapes into the desert and passes his throne to Rameses, who surpasses his rule.
Seti I is the son of Rameses I - pharaoh in the time of Joseph, but unlike his father who discovered a positive attitude to Joseph and his family, he reveals a negative attitude towards them, and when he became pharaoh, he began to subjugate the descendants of Joseph and his family, and so make also his son Rameses II. According to the apocrypha Joseph and Asenath, the son of pharaoh in the time of Joseph, wanted to marry Asenath, and therefore he tried to kill Joseph the husband of Asenath.
Pharaoh's voice actor, Patrick Stewart, also plays Jean Luc Picard in Star Trek: The Next Generation.
He had two daughters and one son with his queen Tuya.
He may have had a daughter named Thermuthis by an unknown woman. Thermuthis is believed to be the one who actually adopted Moses (not Tuya)
He also moved the Egyptian capital from Thebes to Memphis. Ramses afterwards made the capital Pi-Ramses (which was built by Pharaoh Horemheb), which was also where Seti I would build his summer palace.
