Tauran

Taurans were bull-like creatures with grey fur and big muscles. Alinquos had a Tauran bodyguard in The Nocturne. Tasha Williams knew that no one ever won a fight with a Tauran.

A hooded figure had Taurans working for him. He had them capturing alien species, to be released at an unspecified time. The Taurans were killed by a Voltron mistakenly summoned by the figure. (PROSE: What Lurks in the Shadows)
