Ultraa's origin was very similar to Superman's, in that he was born on an alien world, and sent to Earth to escape its destruction. He landed in the Australian Outback and was raised by Indigenous Australians under the alias Jack Grey. Retconned as native of planet Almerac, raised there and arrived on Earth as adult.
