Maab is an antagonist on the Star Trek episode "Friday's Child".
He was portrayed by Michael Dante.
Maab was a Capellan male who was a rival to High Teer Akaar. Maab was in league with the Klingon agent Kras, and was opposed to the Federation gaining the right to mine topaline, which Capella IV was rich in.
Matters came to a head after a Federation delegation, led by James T. Kirk arrived. Akaar seemed more interested in doing business with the Federation rather than the Empire. Maab then made his move and challenged Akaar to combat. Maab bested and killed Akaar, becoming the High Teer of the Ten Tribes.
Maab tried to kill the late Teer's wife Eleen before she could give birth to Akaar's heir, however Kirk intervened. Taking Eleen with them the Enterprise party escaped in to the country side. Maab then took off in hot pursuit of the landing party, with Kras accompanying them.
While Maab and his people pursued Kirk, Spock, McCoy, and Eleen Maab began to reconsider his position towards the Federation. Kras became disturbed that Maab was not the weak willed puppet Kras was obviously hoping he would be.
Eleen returned to Maab and the other Capellans, while Kirk and Spock launched their own assault against Kras and the Capellans. Seeing his chance to eliminate Kirk, Kras betrayed Maab and the others, holding them at bay with a stolen Starfleet hand phaser.
Realizing how badly he had misjudged the Klingons, Maab decided to sacrifice himself. Stepping in front of the Kras, he yelled at the Klingon, who vaporized him with the phaser. Maab's lieutenant Keel used the distraction to kill Kras with his kligat.
