After his return, his parents left Earth to find new worlds to colonize on the exploratory spaceship 'The Starfarer', and were not seen again. According to one version of his story, Chris then vowed to go to Space Academy so he could journey to find them when he was older, and after graduating from Space Academy '99' was appended to his name because of his 99% rating at the Academy, and he later became the greatest space explorer of his day. Another version of Chris's story has him not returning to Earth, but traveling in space to find the last surviving aliens to continue his training with them, appending the KL to his name in honor of the alien race, the K'l, and the 99 in acknowledgement that there were only 98 of the aliens left alive when he was with them. Whatever the correct version, accompanied by Halk, 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'.
