10 Star Trek Characters You Totally Forgot Existed

10. T'Rul

Ladies and gents, Deep Space Nine now has a new starship. It's called the USS Defiant and it's super fired up, armoured to the ends of the earth and has a Romulan cloaking device on loan from the Empire.

Because of this minor fact, the cloak will have to (emphasis on this) be operated by a Romulan. No ifs, no buts.

Which would be brilliant if it were not for the fact that the on loan factor is rarely brought up - but not as little as the disappearance of a Romulan from the bridge of the Defiant.

Appearing in just two episodes, Sub-Commander T'Rul was set to be an essential part of the series thanks to the Defiant's cloak but never appeared again. Luckily for actress Martha Hackett she would drop into Voyager as Seska and the rest is history.

But even if Hackett did traverse to the Delta Quadrant it's amazing how fast the significant presence of a Romulan on DS9 was cut. Never again would there be a Romulan on the Defiant as part of her contingent and activating the cloak would be down to the regulars once The Search was completed.
