Rain is Apello's Exosian daughter. She has a coywolf form with light purple fur and violet markings, tipped ears, and tail, purple hair, and amber eyes. She wears a blue moonstone necklace she gains power from, a black tank top, jeans, and white skull over her left ear.

Rain is shown to have a similar personality to her mother. Tomboyish, sassy, intelligent, and quick tempered, Rain is the most stubborn on the team. However, she does have a soft spot for her family. Rain is also shown to care deeply for Jason, as shown comforting him when he is upset when he thinks his sister is dead. Rain also shows to have a seductive side as shown dancing and singing to distract the evil talent scouts and their new henchmen, as to allow her friends to slip past them.

Rain was given her moonstone necklace by her mother on her 5th birthday, stating she was Chandra, the moon goddess's chosen and she would be able to harness the moon's powers and would be responsible for protecting it once she came of age.

Trivia:

Rain is named after her aunt, Reyna, who has similar purple fur to her.

Ironically, Rain's name is a reference to storms. However, she is responsible for the moon and not storms.

Rain is the first to mention her and her siblings' father, Salazar. While the others think he disappeared during a mission, Rain states he abandoned Cyclonia as evidenced by overhearing an argument between her parents, leading to Sal being banished from the terra. What caused this argument is unknown.
