Jonathan Kent is the father to Superman; he became infected by the Anti-Life Equation and was converted into one of the Anti-Living.

Upon becoming infected he attacked Martha, who was able to knock him into their barn cellar and lock him inside. Once their son returned to collect them Martha informed him of what had happened. Superman then went to see for himself and opened the barn door, Jonathan then attacked Clark who sadly forced him back into the cellar and sealed him inside once again.[1]

Five years later, the Justice League manages to create and distribute a cure to the 2 billion infected still alive on Earth. Including Jonathan, who soon reunites with his grandson and expresses his surprise at how he's grown.[2]
