Moxx of Balhoon
From Tardis Wiki, the free Doctor Who reference
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 an unnamed disease so he travelled around on a fast-moving anti-gravity chair. The chair also replaced his body fluids every twenty minutes so the Moxx doesn't sweat glaxic acid. He greets visitors or friends by spitting in their face, as he shows when he meets Rose Tyler.(DW: The End of the World)
