Samantha has long slightly wavy red hair, emerald green eyes and fair skin; she dons a green catsuit on missions. She is described by her Télétoon and film profiles as rational, logical and mature, like a big sister, although she is known to easily become gullible at times, especially when it comes to romance. She thinks up plans and diversions so that the girls can defeat the villains. Although she is fairly serious during her missions, she enjoys hanging out, shopping, and visiting salons. She is not as boy crazy as the other girls, she has fallen for a few in the series, but without much success. One of the running gags is that she is frequently brainwashed. Her last name is not mentioned in her profiles, however, in "Do You Believe in Magic?", where she is undercover as a reporter, she introduces herself as Samantha Simpson. She is voiced by Jennifer Hale in the English version and by Claire Guyot in the French version. In an interview regarding Sam's development in the first three seasons, Hale described Sam as "smart and adventurous, but now you see more of her wacky side and her girly side as well."
