Rena is a force of nature, both on and off her glidewing. A young racer from The Peaks tribe with pink hair, Rena stands out on the race course, sometimes enough to distract her competitors while she steals the lead. A tomboy through and through, Rena loves proving to Billy that anything he can do, she can do better. Their trash talk resembles flirting too much for Suma’s comfort. Rena, for her part, thinks Suma is a wet blanket who is holding Billy back. Needless to say, the two girls don’t get along. Billy and Rena became great friends after a race where the Pirate King crashed into her. Even though they’re still rivals in the air, they’re there for each other when it counts.
Not knowing she is having a "crush" on Billy, or the two are just friends. No matter what it is, it always annoys Suma.
