American character actor, born 1947 and best known as Mike Ehrmantraut in Breaking Bad, who played Shel-la, leader of the Ennis, in the first-season Deep Space Nine episode Battle Lines.
Jonathan Banks is an American actor with decades of film and television credits, including Airplane!, 48 Hrs., Beverly Hills Cop and the series Wiseguy. He reached his widest audience as the fixer Mike Ehrmantraut in Breaking Bad and its companion series Better Call Saul.
His single Star Trek role came in Deep Space Nine's first season. In Battle Lines he plays Shel-la, leader of the Ennis, one of two factions exiled to a prison moon in the Gamma Quadrant where artificial microbes revive the dead so that their war can never end.
Shel-la meets Sisko, Kira, Bashir and Kai Opaka after their runabout crashes, and shows little interest in peace with the rival Nol-Ennis even when Sisko offers a way off the moon.
