Tetraps looked like they were a cross between a human, bat, and boar.  They were covered in brown fur, had sharp clawed hands and vestigial wing-flaps around their arms.  They had four eyes, one in front, one on each side of the head, and one in back.  They also had four ears, two facing forward and two back.  Tetraps had a forked tongue which could inject a paralysing poison.  They fed on plasma (called amsalp) and slept upside-down like bats.

They first appeared in 1987 in the first episode of the 24th Dr Who series “Time and Rani”.

The episode starts when the TARDIS is attacked by the Rani, an amoral scientist and renegade Time Lord. The TARDIS crash-lands on the planet Lakertya. On the floor of the console room, the 6th Doctor regenerates into the 7th Doctor. In his post-regenerative confusion the Doctor is separated from Mel and tricked into assisting the Rani in her megalomaniac scheme to construct a giant time manipulator.

Lost on the barren surface of the planet, Mel has to avoid the Rani’s ingenious traps and her monstrous, bat-like servants, the Tetraps. She joins forces with a rebel faction among the Lakertyans, desperate to end the Rani’s control of their planet. The Doctor must recover his wits in time to avoid becoming a permanent part of the Rani’s plan to collect the genius of the greatest scientific minds in the universe, of which she has captured many including Albert Einstein, in order that she can create a time manipulator, which would allow the Rani to control time anywhere in the universe, at the expense of all life on Lakertya.

The Doctor manages to foil her plan and free the Lakertyans of her evil control. The Rani escapes in her TARDIS, but it has been commandeered by the Tetraps, who take her prisoner. The Doctor takes all the captured geniuses on board his TARDIS so that he can return them home.

Crazy creatures, a crazy Time Lord, and a pile of crazy scientists together with a confused regenerating Doctor, what self respecting gamer could avoid adding these to their collection……….. well not me anyway!!!! These were picked up on one of the Warlord Miniatures buy 2 get one free sale a couple of years ago (I actually thought I was buying tyres!!).
