Fluke was the keyboardist for the 63rd line-up of Pakafroon Wabster. With the band's popularity on the decline, they went on a trip to Malphapalooza in an attempt to save their careers, but along the way time spillage from the ship's engines placed them in a time loop, during which they constantly relived their deaths in the destruction of their ship.
When the Tenth Doctor and Rose Tyler arrived on the ship in the TARDIS, they tried to save the passengers, but failed and died with them when the ship exploded. During this iteration, Fluke blamed Clifford Banks for the burn holes in the space suits which might have saved them and shot him with an energy weapon. He later threatened to kill Rose, and died when Wabster grabbed him at the same time he fired his weapon. When the loop restarted, the Doctor and Rose, unlike the others, remembered what had happened and used their knowledge to save the band members' lives, expose Jacey's plan to kill them, and free them from the loop. During this last iteration, the Doctor removed the power pack from Fluke's weapon and revealed that the curry he had been eating had been spiked with a psychosis agent. (COMIC: Interstellar Overdrive)
