(Played by Deep Roy)
A native of a sentient, spacefaring species that may or may not be a Federation member in the Nero-derived alternate timeline year 2358. In Keenser’s case, natives are either mute, telepathic, or unable or unwilling to use universal translators to speak verbally. Keenser was the only company Montgomery Scott had during an assignment at the automated Federation outpost on the ice world Delta-Vega, and endured the silent end of a love-hate relationship with the Scotsman.
He was left behind after the visiting Spock and Kirk took Scott with them back to the U.S.S. Enterprise, but Keenser eventually wound up with his onetime supervisor as an engineer on the ship.
