a Martian scientist (once Chief Scientist of Mars), Jero, a Venusian, and a pet chameleon dog, Loopy, whose color changes according to his mood, he discovered many alien worlds (and a sub-atomic universe) in his spaceship 'The Pioneer'. In recognition of his work, he was given the authority to protect the people of the new worlds he discovered from danger as 'Commissioner for Protection of Planetary Peoples'. Chris eventually found 'The Starfarer' and his parents' graves on the planet where they had died saving the rest of the crew in a crash. Other adventures involved saving the ancient Earth monuments from aliens in need of metal to save their universe, and rediscovering a second moon that used to orbit Earth millions of years ago. He was present during the DC Universe Crisis on Infinite Earths, first in his own time to help Superman and the Forgotten Heroes defeat the Forgotten Villains at the start of the Crisis, and then towards the end of Crisis to help with powering the time machines critical to saving the universe.
