The Delta Quadrant inhabitants of Norcadia Prime, a busy and hospitable world where the brutal arena sport of Tsunkatse draws enormous and enthusiastic crowds.
The Norcadians are a humanoid species with a ridged brow, native to Norcadia Prime. They appear in the Voyager episode Tsunkatse, in which the ship puts in at their world for shore leave.
Norcadia Prime is a crossroads for many species, and its most popular entertainment is Tsunkatse, a combat sport in which fighters strike sensors on each other's bodies. Chakotay, Torres and others of the crew become keen spectators, unaware that many of the fighters are captives of the promoter Penk, whose ship broadcasts the bouts to the planet.
One of the former Borg children rescued by Voyager, Mezoti, is Norcadian. She remains aboard after the visit and leaves the ship later with the twins Azan and Rebi, in Imperfection.
