Moxx of Balhoon

The Moxx of Balhoon was a guest onboard Platform One to watch the destruction of Earth in 5,000,000,000, representing the solictors "Jolco and Jolco". He was killed in the heat of the sun's expanding.

His legs were crippled by a disease so he travelled around on a fast-moving anti-gravity chair. The chair also replaced his body fluids every twenty minutes so that he didn't sweat glaxic acid. He greeted visitors or friends by spitting in their faces, such as when he met Rose Tyler. (DW: The End of the World)

The Moxx also had a brother named the Elth of Balhoon, who later avenged his death by kidnapping the survivors of Platform One's sabotage. (DWBIT: Reunion of Fear)
