Purrsephone

Purrsephone (black) and Meowlody (white) are werecat twin sisters. Both Purrsephone and Meowlody are close friends with Toralei, who functions both as their third sister and leader. They are voiced by America Young.

Personality
From their first appearance, they played no other role than lackeys to Toralei, being as scheming and cruel as she can be. They mentioned that sometimes, they go along with another's plans without considering the consequences, or perhaps not even caring. Like Toralei, they live life on the edge, but they also take time to enjoy the simpler pleasures. They also hate when they are treated like they don't have a mind of their own, whether they're being compared to each other, or as lackeys to another monster. Meowlody appears is the dominant one of the two, dragging Purrsephone into schemes she has second thoughts on. Meowlody also has little care for whether others view her as an individual or an interchangeable twin, while Purrsephone is eager to find means by which others could never mistake her for her sister again.

Portrayals
They appear several times in the webisodes, usually by Toralei's side. They rarely speak or produce sound at all, such rare instances being "Road to Monster Mashionals" and "Why Do Ghouls Fall In Love?". They are voiced by America Young.

Physical Appearance
Meowlody and Purrsephone have a mirror theme going on between them. 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. Similarly, while Meowlody has white hair and Purrsephone black hair, they both have a prominent black-and-white striped lock in their haircut, which Meowlody has hanging on her left side and Purrsephone on her right side.

Classic Monster
Just like Toralei, Purrsephone and Meowlody 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.

Family
Their mother has been mentioned in the dairy and they both have each other.

Friends
As shown in Toralei's diary, they are each others' best friend, but are fiercely loyal to Toralei.

Pet
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.

Romance
Neither Meowlody nor Purrsephone seem to be looking for romantic involvement at the moment. However, both went for the same werewolf when looking for a dance partner in "Fright On!", suggesting they have a similar taste in dates.
