Aleu was a wolf-dog hybrid and the daughter of Balto and Jenna. Aleu appeared in "Wolf Quest" as the main protagonist, and made a second appearance as a puppy during Balto's flashback in the song "You Don't Have To Be A Hero" during "Wings of Change". Her name might come from the Aleutian Islands, off the coast of Alaska. She is voiced by Lacey Chabert.
Aleu is 1/4 wolf and 3/4 husky. She is scornful of her wolf blood, but learns to accept it. She also is prone to correcting double negatives, as revealed twice: first to Boris and second to three mean dogs. She spends most of her life at home because unlike her brothers and sisters (who also have wolf in them but don't look it), she isn't wanted by humans.
