The Zakdorn were a humanoidFederation member species. They are characterized by three pouches of thick, fibrous tissue on both of their cheeks.
The reference manual Star Trek: Star Charts, on the star chart United Federation of Planets II, placed Zakdorn at the extreme edge of the Federation in the outer sectors of the Beta Quadrant.
For nine millenia, they were regarded by potential foes as having the greatest innately strategic minds in the galaxy. Because of this perception, no one has tested the Zakdorn in combat, prompting Worf to dismissively note that "the reputation means nothing." As a people, the Zakdorn were generally replete with self-assuredness and overconfidence.
