Khonshu is the Egyptian God of the Moon and the Night Sky. Banished by the Ennead Council, he sought to avenge those that had been wronged by evildoers through his avatars who were known as Moon Knights. Due to the betrayal of Arthur Harrow, his former avatar who had chosen to follow the goddess Ammit whose views were different than Khonshu's, Khonshu chose Marc Spector to be his new avatar. Khonshu planned on preventing Harrow from resurrecting Ammit, but eventually failed despite working with both Spector and Steven Grant. He was briefly imprisoned by the Ennead Council, only to be released later by Layla El-Faouly so he could face Ammit himself. In the aftermath of the defeat of Harrow and Ammit, Khonshu reluctantly freed Spector and Grant from their pledge to him, as they were ignorant that another personality inhabiting the same body, Jake Lockley, would carry on as the next Moon Knight.
Khonshu as the God of Vengeance, Khonshu is an imperious, sort of snotty, vengeful, and impulsive god who is willing to cross almost any extent to reach his goals of imparting his "real justice" on the realm of Earth, through his avatars. Khonshu is an incredibly manipulative god, who preys on broken minds like Arthur Harrow's and Marc Spector's in order to cajole them into imparting his brutal form of justice.
Despite these actions, Khonshu has his more admirable traits. Unlike the other Ennead, he refuses to "abandon" Humanity, charging his avatar to protect the innocent and punish those who prey upon them. For all his brutality against the guilty, Khonshu refuses to harm someone who has done no wrong. While he admits that his goals are not so different from Ammit's Khonshu chooses to oppose her because--his own manipulations aside--Khonshu does respect the choices of others. His haranguing Spector and Grant to protect the scarab seems to have been motivated by a genuine desire to protect the world from Ammit. Beneath all his manipulations and tantrums, Khonshu is courageous and willing to put himself on the line. He helped his Avatar by temporarily manipulating the sky, knowing that doing so would result in his imprisonment, and later chose to personally battle Ammit despite the latter being stronger than he. Khonshu also demonstrated some degree of trust in Spector, entrusting him to free him after he was sealed away.
