|Robo Of Choice||Miranda|
|Game||Custom Robo (Arena)|
Serene is the champion of Forester Prep, Hillside District's elite academy. She is the first person to use the Soulboost and is the main rival in the second round of custom robo battles. She managed to get in the Robo Cup, but she couldn't get a good ranking in the end. She is very close to her sister Polly. Polly even fought the hero to avenge her sister's defeat. Lunax, the leader of the Super Novas, seems to have a crush on Serene, but the hints are only given in the Spanish version.
Her robo of choice is Miranda, which somewhat resembles her.
