Malmooth

The Malmooth were a humanoid insectoid race native to the planet Malcassairo. (DW: Utopia)

Biology
The Malmooth were beings with blue, chitinous skin and a tall head. They had a pair of mandibles at the side of their Human-like mouths, however the only purporse they seemed to serve was to express emotion. (DW: Utopia)

Culture
The Malmooth language required its speakers to divide their name into two syllables and speak them at the beginning and the end of each sentance, for example "Hello" would become "Chan-Hello-tho" in the case of a Malmooth known as "Chantho". To not do this would be akin to swearing in other languages. (DW: Utopia)

History
The Malmooth evolved on their homeworld of Malcassairo and built an organic city where they lived. However, with the dying of the universe, the city decayed and nearly all of the Malmooth became extinct, save for a young female called Chantho, who worked with Professor Yana at Silo 16 on Malcassairo. Chantho was later killed when Yana returned to his old self - the Master - however not before she shot the Time Lord, triggering his regeneration. (DW: Utopia)
