Angela Costain is best known for voicing Nabiki Tendo in the English dub of Ranma ½, a role she held through most of the series' run. She also voiced Ryonami.
The one notable gap in her work came during Season 6, when Costain stepped away to attend flight school. Her sister Elaina Wotten-Costain filled in for her during that time, but Costain returned to the role starting with Season 7.
Beyond anime, Costain has appeared in live action TV work, though Ranma ½ remains her only venture into voice acting for anime.
