Rylibeu is a butterfly-like humanoid alien. She has pink skin, pointed ears, green eyes and two antennas on her head. She wears a green tunic.
As shown during her fight with Basil, Rylibeu seems to lose concentration too easily; after being scolded by Rumsshi for falling out of the ring, she admits that she forgot how to fly with her wings.
Despite being the first eliminated, Rylibeu quickly recovered when prompted by Gowasu and immediately turned to cheer on her teammates.
When her universe is about to be erased, she, like the rest of her teammate closes her eyes and accepts her fate.
