Tritovore blaster
From Tardis Wiki, the free Doctor Who reference
A Tritovore blaster was a small energy weapon used by the Tritovores. It had violet lights on its right and left sides. On San Helios, a Tritovore (either Sorvin or Praygat) tried to use his blaster to kill a Stingray which had eaten a fellow crew member, but was eaten instead. (TV: Planet of the Dead)
