Sprite (Lia McHugh) is a character in the Marvel film, The Eternals. She’s an Eternal, an immortal, superpowered being created to eradicate Deviants to help populate the Celestial race. Sprite and nine other Eternals get sent to Earth but are forbidden to interact in human conflicts. She has the ability to project realistic illusions. She is close friends with Sersi, but she also has an unrequited crush on Ikaris, which causes jealousy. At the end, Sprite requests that Sersi uses the remaining energy from the Uni-Mind to turn her into a human. This allows her to start aging, thus ending her unwanted childlike appearance.
