Star Trek: 10 Things You Didn't Know About Weyoun
2. Count Them Up
Across the course of DS9 there are five Weyouns to appear on screen, leaving Jeffrey Combs with the dubious honour of being the person killed the most times in Star Trek history. Four is eliminated in To the Death, Five dies offscreen in a mysterious transporter accident that Damar has nothing whatsoever to do with. Six takes his own life aboard a Runabout with Odo in Treachery, Faith and the Great River.
The seventh clone has his neck snapped by Worf rather unceremoniously when he and Dax are captured during the ten-part finale. Eight would be terminated in What You Leave Behind by Garak marking the end of the clone line since their production facility had been destroyed.
The first three Weyouns are never mentioned in the series with both theirs and Weyoun Five's death occurring off-screen.
