Iona Morris (born 23 May 1957; age 59) is an actress who, like her brother Phil Morris, first appeared in the Star Trek franchise as a child, playing an Only in the original series episode "Miri". Also like her brother, she would go on to reappear on Trek; in Iona's case, she played Umali in the Star Trek: Voyager episode "Workforce". Her brother had previously appeared on Voyager in the episode "One Small Step". She and Phil are the children of Mission: Impossible star Greg Morris.
Morris attended the same high school as L.A. Law star and Star Trek: The Next Generation guest actor Corbin Bernsen. Morris and Bernsen would subsequently co-star together in an episode of Citizen Baines, starring James Cromwell and Matt McCoy.
After her first Trek appearance, Iona Morris went on to make guest appearances on such television shows as the 1980s update of The Twilight Zone (in a segment with Terry O'Quinn), Night Court (co-starring with John Larroquette and Bumper Robinson), Hill Street Blues (starring Megan Gallagher and James B. Sikking, in an episode with Marc Alaimo and Eric Menyuk), The Cosby Show, Murder, She Wrote (with Leon Russom), Moesha, and The District (starring Roger Aaron Brown). 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.
