Beeza is the leader of the species whose planets have been constantly destroyed by Buster, the giant dog. She is used to this by now and takes the destruction as if it's no big deal.
She is a short gray-skinned alien with dark turquoise hair and large black eyes with white pupils. On her forehead is a wheel-shaped ornament with what appears to be two feathery yellow antennas coming out of it. She wears a simple pink robe with a purple sash around her waist. Overall she resembles most female members of her species.
Beeza is a friendly and calm character who is always polite and hospitable to others. Due to her home planet(s) having been destroyed so many times, she takes the destruction and chaos lightly. Having experienced apocalyptic scenarios so many times, she has become indifferent to the thought of mortal danger and does not seem to mind the idea of being captured, tortured or destroyed, as seen when Lord Hater threatened her in "The Rager". Because of this, she comes off as very easy-going.
Beeza is voiced by Tara Strong, the same female actress who voices Timmy Turner and Poof in The Fairly OddParents series, Bubbles in The Powerpuff Girls series, Twilight Sparkle in the My Little Pony: Friendship Is Magic series, Raven in the Teen Titans and Teen Titans Go! TV Series, and more.
In Latin America, she is voiced by Camila Díaz Fraga, who is also currently the official Latin American dub actor for Dove Cameron. ("Liv and Maddie", "Cloud 9"), as well as additional voices on Wander Over Yonder.
