Rudy Zoom was the boss of an expedition to go to the Sun and, in his own words, a "handsome quadrillionaire".
When Rudy was ten, he built his first hoverbike. When he was twelve, he started selling them. By the time he was sixteen, he was worth sixty billion pounds. He claimed to be the first man to swim the Mariana Trench, the first man to climb Olympus Mons and the first man to "cycle the rings of Saturn". Eventually, he aspired to be the first man on the Sun, and hired an all-woman expedition to do so. Professor Alice Dubrovnik believed him to have been a "reckless, egotistical fool", but also pointed out that he was also the only one to fund Alice's work on the graviton inverter. Alice's graviton inverter was used on the sunship the Pollyanna to stop the Sun from crushing it with its gravity. After ten years of planning, the expedition of the the Pollyanna reached the surface of the Sun. When the Umbra had infiltrated the Pollyanna, Rudy offered to negotiate with them. Clara Oswald, realising what might happen, eventually agreed and encouraged him, as it was their last chance. When the Umbra tried to devour Rudy's mind, his mind was "like poison" to them, as he didn't have any self-loathing in his mind for them to feed off. (COMIC: The Eye of Torment)
