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.
In United States, Beeza is voiced by Tara Strong, and 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.
