Sersi () is a fictional character appearing in American comic books published by Marvel Comics. The character is depicted as a member of the Eternals, a race of superhumans. She was also a member of the Avengers and God Squad. Sersi first appeared in the 1976–1978 comic book series The Eternals. Gemma Chan portrays Sersi in the Marvel Cinematic Universe (MCU) film Eternals (2021). Publication history Sersi first appeared in The Eternals #3 (September 1976) as Sersy. Although The Eternals was published by Marvel Comics, it was not treated as part of the Marvel Universe, but rather as a stand-alone series. The characters were later incorporated into the Marvel universe. In the 1980s, she made guest appearances in the series The Avengers and Captain America. Later, Marvel Comics continuity was retconned so that Sersi was the Greek mythological enchantress Circe, as introduced in Strange Tales #109 (June 1963). In 1990, Sersi joined the Avengers team, after her fellow Eternal Gilgamesh left the team following an injury. Sersi left the team in 1994. After Malibu Comics was acquired by Marvel, Sersi and the Black Knight were incorporated into the short-lived Ultraverse imprint along with other Marvel characters. During the 2006 relaunch of the Eternals, the character was redesigned by Neil Gaiman. Sersi and the other Eternals returned in Jason Aaron's Avengers. They were then all killed in a story arc involving the Dark Celestials in issue #4.

Although Sersi still had the appearance of a child at this time, she was already thousands of years old.
