Sprite (Eternal)

Although physically a child, Sprite is an Eternal, a member of an ancient and extremely powerful immortal race, who is commonly depicted as a mischievous trickster figure.

[4] Sprite later advocates the appointment of the Black Knight as Sersi's Gann Josin (sharing a mental bond) as compromise with Ikaris, who wants her killed.

Although he presented himself to be unaware of his past or abilities, he also served as a spokesman for Hero Registration (as the series is set during the Civil War event).

[9] Sprite was later seen boarding a train to run away from the problems he caused that led to the awakening of the Dreaming Celestial, and was ultimately found by Zuras.

Sprite has no apologies for causing the current situation, and, satisfied with the life he lived, although promising vengeance, allows Zuras to kill him by snapping his neck.

Sprite, in his former incarnation, successfully used the reality-warping powers of the Dreaming Celestial to provide himself with a human body that would have aged to adulthood normally, if not for his demise.
