Like all Eternals, Sprite has superhuman strength, can mentally manipulate gravitons enabling levitation and flight, can mentally create illusions to disguise his form, and has a limited ability to psionically manipulate atoms and molecules to rearrange the shape of objects. He can project cosmic energy as heat, light, and concussive force. Sprite's life force is augmented by cosmic energy granting him a lifespan of thousands of years, immunity to disease and aging, and is virtually indestructible.
Sprite is a mischievous Eternal who maintains a perpetual youthful appearance. He was the inspiration for Shakespeare's character Puck in "A Midsummer's Night Dream." Once, after fellow Eternal the Forgotten One (the Avenger "Gilgamesh") fell in battle with the Lava Men, and was sent to Olympia to recuperate, Sprite's well-intentioned tinkering with the city’s malfunctioning concealment technology had cast Olympia into the otherdimensional Negative Zone. There, the warrior Blastaar blew the Eternals to atoms, but they soon regained their physical forms and defeated him with the aid of the Avengers and Asgard’s Warriors Three.
Recently, while hiding his identity, Sprite became a television child star.
