Kornan
From Tardis Wiki, the free Doctor Who reference
General Kornan was a Kchrusivour who led an attempt to invade Earth in the 23rd century by posing as harmless Zonians. This plot was thwarted by the Eleventh Doctor. He reversed and locked their perception filters. This left them trapped in Zonian form and they were taken prisoner by the authorities. (COMIC: The Kchrusivour Gambit)
