01 The Psychlos would win.
The Psychlos stand at 9 Evans tall whereas a Sontaran is a shortarse only being as tall as a trio of Evans'.
In addition, the Sontarans look like baked potatoes and are often killed by small children wielding sporks who have mistaken them for 'tasty' Spud'u'like meals.
Finally, Sontarans have an on off switch on the back of their necks which is a pretty stupid evolutionary feature if you ask me! You don't hear the bleedin' Creationists bragging about 'God's Grand Design' when the word Sontaran pops up in polite conversation! Oh no you don't!
In July I stood next to a Sontaran and I felt like pushing it over. (They make many people/species feel that way because they make a low humming sound that agitates the Side Wings of the Torment Brain. They also smell of pig vomit which not everybody likes.
Anyway, I wish I had now!
