Melanie Merville

Melanie Merville is Ranger 3, the Yellow Ranger of the Train Quasar Guardians.

Personality
Melanie is the twin sister of Niles, having been born several minutes after him. She is a sports-minded young woman with a confusing character. Though she is more of a tomboy, she is really good at housework. Because of this, she is quite popular with the boys; although, she hates the idea of romance. Alice acts as the team's big sister, not having a tolerance for under handed attacks.
