Vampiro was a professional wrestler, who also happened to be an Eternal. Among the 100 other Eternals created by the Celestials a million years ago, he was tasked to protected humanity for centuries. Transitioning from his celestial duties, he embraced a dual life as a beloved professional wrestler named "El Vampiro," facing challenges that intertwined mortal and Eternal conflicts, ultimately meeting his demise in battle against the Deviant El Toro Rojo.
Despite a presumed demise during the Eternals' collective madness, Vampiro later resurfaced, joining Druig's faction before meeting a tragic end in a confrontation against the alien Horde in San Francisco. However, their battle was interrupted by the arrival of the alien Horde which caused the two sides to unite against the common threat. The rest of the Eternals joined the fight but Vampiro was killed by a Horde bug before the threat was neutralized.
Months ago, after learning that the true purpose for which they had been created by the Celestials was not what they had thought it was, all of the Eternals were driven mad by the dark truth. In their madness, they either killed each other or committed suicide. Vampiro was presumably among those who died during this madness.
Following this mass murder/suicide event, all of the Eternals were eventually resurrected by the Machine. "Vampiro" would have been one of them.
