She is a zebra with predominant black stripes throughout her body, characteristic feature of the species. Unlike real zebras, Ellen's mane is entirely black, with no stripes or white tones on it. She usually wears a regular female's school uniform.
Ellen is shown to be easily scared of carnivores and is the first to blame one of them for Tem's death. In spite of this, she seems to be a very nice girl who cares deeply for her friends.
- In the anime, Ellen can be seen dancing at the Meteor Festival, even though she belongs to the acting team and not the dance team.
