Apollo "Ollie" Sunday (voiced by Finlay Stroud) is the son of George and Janet. He is born at the end of series two, and, like his father, possesses superhuman powers, although they are somewhat limited. The name "Apollo" was chosen by Ollie himself during a conversation with Tyler, and is meant to symbolise the link between two "heavenly bodies" (either "Apollo 11" or "Battlestar Galactica"). George originally wants to name him Pontius after Pontius Pilate, and Janet opted for Benjamin, until Tyler informed them that Ollie did not like either name. Despite being a baby, Ollie speaks fluent English and has a full set of formed teeth. By the fifth series, Ollie claims to know virtually all Earth languages. During this series, his character takes more of a back seat as he fights sibling rivalry wars with his newborn sister Cassie.
