Actress
She was also seen in an episode of Homeboys in Outer Space, which featured TOS star James Doohan in a recurring role. In addition, Morris has become well-versed as a voice actress, voicing regular roles on Robotech (as Claudia Grant) and the Problem Child animated series.
Perhaps most notably, she was the original voice of Ororo Munroe, a.k.a. Storm, on the 1990s animated X-Men TV series; John Colicos voiced the role of Apocalypse on this series. Morris also voiced Storm and the character of Martha Robinson on the Spider-Man animated series. In 2006, she would return to Robotech to voice Dr. Jean Grant in the animated file Robotech: The Shadow Chronicles which also stars Chase Masterson.
One of her few film credits is the 1992 drama Rain Without Thunder, which featured Voyager star Ethan Phillips as a gynecologist.
More recently, she has done voice overs for the video games Sly Cooper: Thieves in Time, Grand Theft Auto V, and Fallout 4. These days Iona is still acting and works behind the scenes on many projects.
