8. The Asari

Game Appearances: Mass Effect

Original Gender: Hermaphrodite

In the Mass Effect universe, the Asari are a race of sexy blue aliens that just happen to have the ability to mate with any creature of any race and any gender. While their outward appearance may seem most similar with a human female - save for the blue skin and tendril hair - they don't actually have males or females on their planet. Every single Asari is the same biologically and their equipment works with whatever their mate happens to carry making them perfect companions for threesomes.
