The handsome young Antonio remembers little about himself aside from his first name.  Research into his records identifies him as the son of a wealthy Mexican family with a history of mental illness.  Police reports indicate that Antonio ran away from the mental health facility his parents paid exorbitant rates to house him in, and lived on the streets by stealing and scavenging.

Antonio's first memories place him at the scene of a car accident, where he erupted.  Antonio's instinctive teleport saved his life, but sent him into the arms of Proteus.  Experimented on, tortured, and marked as dead in all official records, Antonio only managed to escape because of a strong drug resistance and his own cleverness.  Teleporting in a sequence of random jumps and staying one step ahead of Proteus operatives, Antonio sought out the one man he trusted since he was an awkward teenager playing with T2M:A action figures: his hero, Comstock.

Now, recovered from his ordeal but still lacking any memory of his life before eruption, Antonio shadows Comstock, offering assistance and allegiance at the cheap cost of a bit of fatherly approval.
