Behind the scenes
According to the non-narrative source, The Ultimate Monster Guide, which this wiki does not consider a valid source, his legs were crippled by a disease, so he travelled on a fast-moving anti-gravity chair. The chair also replaced his body fluids every twenty minutes so he didn't sweat glaxic acid. His favourite song was "Yap Cap Forward Bigga Toom Toom Toom".

According to Doctor Who: The Encyclopedia, he was portrayed by Jimmy Vee but voiced by Silas Carson.
