Meowlody is a 2011-introduced and all-around character. She is a werecat and a student at Monster High. Meowlody, principally recognizable for her white hair, has a twin sister by the name of Purrsephone, who is principally recognizable for her black hair. Along with Toralei, their best friend, sib from another crib, and leader all rolled up in one, the trio are some of the worst causers of trouble at the school. Despite giving Toralei the reins under most circumstances, Meowlody has a crafty mind of her own and can operate solitarily or while instructing her sister. Though she and Purrsephone get along well, Meowlody often is insensitive to her needs and wellbeing.
Meowlody is rarely heard speaking, but she occasionally makes cat sounds. In the English version of the cartoon, credit for this goes to America Young, who also voices Toralei and Purrsephone.
While Meowlody is prone to reliquish the role of criminal mastermind to Toralei, she is just as well off without her. Meowlody has a penchant for pranks all of her own and is willing to take risks to execute them. Her sister and default partner-in-crime is not all that pleased with that, but Meowlody needs little effort to convince her to join in. Given her enthusiasm, Meowlody doesn't respond too well when a prank backfires, liking neither the consequences nor that the prank itself never reached its potential.
While Purrsephone is frustrated that she and Meowlody are seen as interchangeable, Meowlody is not at all bothered by it since the kind of people that think that are the ones that don't matter to them. In fact, she likes the extra edge of confusion being part of a set of twins gives her.
Meowlody has a mirror theme going on with her sister in how they look and how they dress. Both have a grey skin or fur and white facial marking. They also have white stripes running over their legs and arms, but Meowlody has her stripes on her right arm and left leg, while Purrsephone has them on her left arm and right leg. Meowlody is more easily distinguished from her sister by her hair though, which is white, whereas Purrsephone's is black. In line with the white markings on their limbs, Meowlody has a black-and-white striped lock of hair hanging from her left side, which Purrsephone has hanging from her right side.
Meowlody and Purrsephone dress in similar outfits because it's easier for them. Like Toralei, they have a biker look going for them, but the twins' choice of clothes reaches more for the feminine. The main colors they go for are white, black, crimson, and orange, with black and orange being more dominant in Meowlody.
Just like catty, Toralei, Meowlody and Purrsephone are werecats. According to folklore, they are humans who transforms to human-like cats, panthers or tigers. Werecats are similar to Werewolfs, as Werecats are also known as "shape-shifters".
Werecats are not featured as often as Werewolves are in popular culture, but a notable movie with Werecats is Cat People directed by Val Lewton. It tells the story of a young woman, who believes herself to be a descendant of a race of people who turn into cats.
Meowlody is the twin sister of Purrsephone. They live in a good household, where their pranks are not approved of but generally not reported on either. Their mother dotes on them and has so far denied Purrsephone the possibility to throw away embarrassing photos from when she was a child and affected by hairballs because she thinks the photos are cute.
In her diary, Toralei says that Meowlody and Purrsephone are "like [her] sisters". This sentiment is presumably shared by Meowlody.
Meowlody's best pals in life are Purrsephone and Toralei.
Until some years ago, Meowlody and Purrsephone owned a male canary who would sing them awake every morning. However, Purrsephone developed an allergy to the bird, forcing the sisters to give him away. They still miss him.
Meowlody and Purrsephone went for the same werewolf when looking for a dance partner in "Fright On!", suggesting she has a similar taste in dates as her sister. Though Purrsephone hasn't been in romantic context since, Meowlody has caught the attention of Manny Taur, who gave her flowers in "Hiss-toria". She appreciated that and expressed jealousy when Manny and Iris started dating
