In William T. Quick's two novels detailing the aftermath of the Oberon's crash on the planet Ashlar, Jonathan was one of the central characters. He was the genetically-enhanced son of chimpanzees Pericles and Aspasia . After Pericles had disappeared in the electromagnetic storm and the Oberon had crashed onto the nearby planet, surviving humans Grace Alexander and Molly Benavides decided to instil genetic improvements in the still-unborn foetus to improve the colony's chances of survival. The enhancements caused the death of Aspasia, but Jonathan was born safely and raised by Molly, who had recently given birth to a son, David, fathered by Leo Davidson before he too had disappeared in space.
