The Zygons of Zygor, are shape shifting aliens that contain venomous sacks within the tongue and are apparently, surprisingly good kissers.
Their home planet, Zygor was destroyed in a stellar explosion, or in the Time War. Doctor Who writers are quite indecisive.
|Hey sweetcheeks, apparently I'm a great kisser, so pucker up!|
Giant, orange and covered in suckers, the Zygons have red blood and speak in a whisper and a gurgling voice both at the time. They are hermaphrodites but when younger, are white in colour, suckerless, feminine and graceful. Obviously as they got older, things went very wrong.
Most of their technology seems to be quite organic and the interior of Zygon ships could easily have been created from coral or a living substance. They have also created the Scarasen, which is organic, stupid, produces milk and is known as the Loch-Ness monster because of its time in Scotland. The Zygons feed off it's milk which is just wrong and rather disgusting.
