Quiox
From Tardis Wiki, the free Doctor Who reference
Quiox was considered one of the most dangerous planets in the universe. It was home to all manner of predatory life forms. Among the more notable species were the giant Night Butterfly and its larvae. For some years Agent 99 managed to live a quiet life in hiding holding a position of respected authority before leaving with the Doctor and returning to Earth. (DWAM: The Secret Star Trail)
