Sam Sharp is a minor character in The Loud House. She is one of Luna's band-mates and her girlfriend, who makes her first appearance in the episode "L is for Love", in which it is revealed that Luna has a crush on her. In "Racing Hearts", she starts reciprocating her feelings towards Luna.
Sam is a thin girl with light skin, blonde shoulder-length hair with a teal streak in her bangs and four pairs of eyelashes. She has two helix piercings in each of her ears and wears pink eyeshadow.
Her outfit consists of a short, teal leather jacket with a crimson patch bearing a white skull on the back, a white T-shirt with the roundel of the RAF on the front, a pair of deep burgundy jeans cut at the knees, a black belt with silver studs, and a pair of dark purple boots.
According to Kevin Sullivan, during his first pitch of "L is for Love", Sam was named Max, which is also a unisex name.
In the Listen Out Loud podcast it's revealed the she is a volunteer at the Royal Woods animal shelter.
Contrary to popular belief, Sam was not named after writer Sammie Crowley, as Kevin Sullivan stated that he wanted her to have a name that both males and females could use, which would add in confusion to what Sam's real gender was.
According to Kevin Sullivan, Sam appears in new Loud House comics, and Listen Out Loud podcasts.
