Sam Manson is one of Danny's best friends and one of the few people who know about Danny's ghost identity. She is a self-proclaimed goth who's fascinated with the subliminal and nether worldly and is a very outspoken ultra-recyclo-vegetarian. She is sarcastic, forceful, bossy, passionate, and strong-willed, but also good-hearted and caring. Out of the three, Sam is usually the most rational and mature, often thinking on a realistic level compared to her friends and pointing out to Danny to focus more on ghost training and hunting.
