Marie is the daughter of Shadow and Zephyr. She has black fur, blue eyes, and a red stripe on her head.
Marie was named after her father's only human friend, Maria. When Marie met the Rangers, she was excited to meet them, being Rosey's best friend. She had always been a fan of the Rangers but was more of a Sydney Cooper fan than a Raiden fan.
Marie is shown to be wild, reckless, and a ball of energy. She hates sitting still and doing nothing. She looks up to her father and always seeks to impress both of her parents, seeing nothing scary or frightening about them, reminding her father of his old friend Maria. She enjoys dancing and singing alongside Rosey. She also shows to have a close relationship with Flash, holding a crush on him.
On her initiation ceremony, she befriends a stygian Zinorgre, naming him Tartarus.
