Charles "Chuck" McCabe (born February 11, 1960s) is the husband of Patty McCabe. He was the adoptive father of Mari in the original timeline where Mari's village was destroyed, but the heroes known as the Legends prevented its destruction so Mari was never an orphan.
After bailing Mari out of prison, the two talked as they ate. While leaving, they were later jumped by a couple of thugs. Chuck offered his wallet with all of its contents, but he was knocked down. Mari was able to tap in to her necklace and beat the thugs, though unbeknownst to Mari. They headed back to Chuck's house, where he gave Mari coffee, offering something stronger if she wished. He suggested she stay in her old room, but she left instead. When she returned, Mari spoke of her belief that her necklace was magical. Despite his skepticism, she demonstrated a feat of strength with the kitchen table, before they headed outside. Mari demonstrated climbing up a wall for Chuck, before also almost jumping from a ledge like a bird. However, she instead came inside. Mari voiced her belief that her necklace would reveal answers to her past, before Chuck got up to answer the door. He was confronted by the Flash and the Arrow, who began to chase after Mari.
When Amaya Jiwe lost her totem, it caused a ripple in time that created a version of history where Mari never received her totem and had become a vigilante hero in Detroit without her powers. She had been hurt trying to save people in a burning building and Chuck had gone to the hospital to see her. He had been approached by Nate Heywood and Wally West, who had come to check on Mari in place of Amaya. They posed as journalists and told Chuck they wanted to do a story on his daughter's heroism, but Chuck told them that he would prefer that Mari learn to take better care of herself.
Because of the Legends' intervention in Zambesi 1992, Mari never became an orphan, therefore she was never adopted and raised by Chuck, along with his wife Patty.
