Judoonia

Judoonia was the home planet of the Judoon. It had mountains 1,000 miles high. (AUDIO: Judoon in Chains) Nukeball was forbidden on the Judoon's home planet so the population was not wiped out. (PROSE: The Coming of the Terraphiles)

In an alternate timeline, the inhabitants of Judoonia had been mostly converted into Cyber-Judoon by 2493. (COMIC: Assimilation2)
