American stage and screen actor who guest-starred in Deep Space Nine as Verad, the rejected Trill candidate who seizes the station in order to steal the Dax symbiont.
John Glover is an American actor with a long career on stage, in film and on television, known to genre audiences for playing Lionel Luthor in Smallville and for films such as Gremlins 2: The New Batch and 52 Pick-Up.
His Star Trek role came in the second-season Deep Space Nine episode Invasive Procedures. He plays Verad, a timid unjoined Trill who was turned down by the Symbiosis Commission and who boards the evacuated station during a plasma storm with hired Klingon mercenaries to take Dax for himself.
Glover plays the part twice over: first as the nervous, resentful Verad and then, once the symbiont has been transplanted, as the far more assured Verad Dax, who greets Sisko as an old friend.
