Vindor is the towering champion of the crystal-revering Gelrakians, whom Commander Jack Ransom defeats in single combat to free a Cerritos away team in the episode Temporal Edict.
Vindor appears in Temporal Edict, the third episode of Star Trek: Lower Decks. When Ensign Vendome presents the Gelrakians with a wooden fertility totem in place of the promised honour crystal, the insulted locals attack the away team and take them prisoner.
Their leader offers a trial by combat: one officer must face Vindor, a huge warrior who seems able to bellow only his own name. Mariner and Ransom argue over who should fight; Ransom settles it by stabbing her in the foot, then strips off his tunic and batters the champion until he yields.
Beaten, Vindor admits that he only pretends to be a simple brute. He lets people think he can say nothing but his name, when in truth he loves to read.
