Jingo clan
From Tardis Wiki, the free Doctor Who reference
The Jingo clan were a group of Sontarans of which Jingo Linx and Jingo Trak were members.
A feature of the clan was a shade of skin akin to rotting wood, (PROSE: Lords of the Storm) except for Trak, who instead had been enhanced with cybernetic features. (GAME: Lost in Time)
