Grace Santana was the wife of Chato Santana. She was accidentally killed by her husband when he lost control of himself and his powers.
Grace married Chato Santana and had a son and daughter with him. Eventually, Chato used his pyrokinetic skills to his advantage and became a crook, becoming known as "El Diablo" on the streets. Upon Grace discovering his criminal activities by finding a stash of money and a pair of pistols, the two had an argument, with Grace threatening to take their children away to her mother's. El Diablo lost his temper, which led to him having a hard time controlling his pyrokinesis. This resulted in an enraged El Diablo setting their house ablaze, unwillingly killing both Grace and their children. A devastated, remorseful El Diablo handed himself over to police custody voluntarily.

- ―Grace to Chato Santana[src]When El Diablo's mind was telepathically assaulted by Enchantress, the latter implanted a vision of El Diablo being with his family, with both children sleeping on the couch next to their father. All of a sudden, Grace came in the living room, asked Chato if he missed her. She suggested to put the children to sleep and spend time together with her husband.
