When in his mother's womb he was damaging her but his mother would not abort her child. She died 6th months into her pregnancy and her child was taken from her womb after her death and surprised the doctors to find that he was fully grown to a baby and in great health. His father took him in but started blaming him for the death of his wife. As time went on he started drinking and started abusing his child. Eventually when in a angry fit he locked his son in a freezer. The boy found the space becoming unbearable (his power activated and made the space sterile) and started pounding on the door. Getting angry his father got a stick to beat his child and opened the freezer. The child jumped out at him and grabbed his face with his hands. The touch did hurt his father but the father then died of a heart attack. Blaming himself for his father's death the boy ran away and began living homeless.
Gauntlet is an NPC that can either be a villain or a friend to the heroes. He has a power that he has no control over, a power that will kill people that he has skin to skin contact with, and this means any person with a cellular structure. Because of this he considers himself to be a monster (and may even be one) and is very protective of the homeless of which he is one as well.
