Maston

Mastons are large predators native to Sentimenous Virgo. They generally weigh around 120 kg and are around 2.10 metres tall. Mastons are large and hairy and have a powerful tail. They can easily overpower a Human, but they aren't especially intelligent.

The Mastons were driven to extinction millions of years ago when their planet was destroyed. The computer of the Vipod Mor brought a Maston forwards in time to attract the Doctor and to distract the crew.
