Wabster was the founding father of the rock band Pakafroon Wabster. He died in a bizarre rollerblading accident, but fifty years later he was dug up and animatronically reanimated. He accompanied the current line-up on a trip to Malphapalooza, 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, Wabster died when he saved Rose from Fluke by grabbing 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 reprogrammed Wabster to power down the engines. When Jacey tried to shoot the band members herself, Wabster saved them by grabbing her at the same time she fired her weapon. This jolt of energy stimulated his neural pathways, bringing him fully back to life. (COMIC: Interstellar Overdrive)
