The publicly acclaimed inventor of the GRAF Shield, Xenobius was an Alpha Neosapian scientist. Algernon, the true Inventor of the GRAF Shield, allowed Xenobius to take credit for his invention under the condition that Xenobius would shield from the rigors of the everyday world and allow him to work in piece. This arrangement was in place for almost a year when it finally fell through. When Professor Algernon sabotaged the GRAF Shield on Venus, Xenobius was forced to take the blame for shield’s failure. He was never seen again and presumed killed.
