Apophis was once an extremely powerful Goa'uld System Lord. The brother of the Supreme System Lord Ra, he originally commanded a minor fleet, but he grew in strength to command the power of multiple System Lords that had been killed during his reign, ultimately succeeding Ra as the dominant System Lord after his death. He held one human host in his life. He was one of the most powerful enemies of the Tau'ri and a personal enemy (ultimate nemesis) of SG-1 due to the fact that he had taken Sha're, Daniel Jackson's wife and Skaara, Daniel's brother-in-law as hosts for his Goa'uld family as well as an enemy of Teal'c of Chulak who had served Apophis as his First Prime before defecting to join the Alliance stop Apophis once and for all.
