Samantha "Sam" Manson is a gothic female student, Danny's best friend and girlfriend, Tucker's best friend, and an ultra-recyclo vegetarian who, in the first episode of the series, changes the menu to grass on bread and gets covered in meat by the Ghostly Lunch Lady. She takes pride in being unique, and often insults Paulina by saying she's "a dime a dozen"; even though, she is jealous because Danny likes Paulina and Sam likes Danny. On the surface, she's tough, but sometimes, showing that she's really got a heart of gold.
Sam appears as one of the dueteragonists in the Nickelodeon animated television series Danny Phantom. She is voiced by Grey DeLisle.
