Commander Bai is a formerly attractive alien who becomes a villian in Space Face Part 2 . It is revealed that, being the "most attractive race in the universe", Bai's people found a way to convert their own self-esteem into energy with which to power their space ships. However, during a routine mission to pick up space beer, their ship's hyperdrive malfunctioned and sent him deep into space, along with his crew, where they became stranded. During the time spent stranded in deep space, the aliens eventually let themselves go, meaning they could no longer use their vanity to power the ship, leaving them stuck. They then embarked on a mission to find a being vain enough to power the ship, fix their hyperdrive and send them home again, which is why he abducts Matt.
