While in Cardassian makeup to film her Star Trek role, she "took the opportunity to walk around the lot at Paramount and scare the schoolchildren on buses. Until finally Security called the stage at DS9 and said, 'Could ya'll do something about keeping your aliens contained over there?'" 
She is perhaps best known as Elizabeth Lochley in Babylon 5 and its spin-off Crusade, working with Andreas Katsulas, Bill Mumy, Patricia Tallman, and Walter Koenig on the former and Daniel Dae Kim on the latter. Scoggins reprised her role in the Babylon 5 DVD film, Babylon 5: The Lost Tales - Voices in the Dark.
Before Babylon 5, she had regular and recurring roles on Lois and Clark: The New Adventures of Superman with Teri Hatcher and K Callan, Highlander, Dynasty with Joan Collins and its spin-off The Colbys with Ricardo Montalban, Joseph Campanella, and Judson Scott.
She starred in the 2004 television movie Homeland Security, in which Andrew Robinson, Megan Gallagher, Leland Orser, and Glenn Morshower also appeared. She also had a guest appearance on the short-lived TV adaptation of the film Blue Thunder, which Jeri Taylor produced.
