History: (Mystery in Space #103)-In the next hundred years Earth will develop a boombing buisness shuttling tourists to planets across the solar system. Ace Arn was a pilot taking tourists to Jupiter when he was forced off-course by a comet. His passengers escaped, but Ace crashed into an asteroid.The asteroid was home to a criminal gang, one member each from the worlds of Ulla, Laroo, Trago and Raagin, as well as a scientific mastermind named Zobra. Zorba designed duplication weapons and orchestrated a blackmail scheme against the four planets. Zorba accidentally accidentally killed himself before he could reveal the plans, and one criminal of each race went to his lab to recover the blackmail scheme. They discovered Ace, who had landed inside the lab, and shot him with their duplicator weapons. As a result of four duplicator rays hitting him at one time Ace was transformed into a multi-being, possessing the powers of all four aliens. Ace defeated the gang, and returned to Earth to start a career as a crimefighter. He named himself Ultra, an anagram formed from the worlds his alien powers came from.
