Pepper is a very fun, comedic little skunk who loves to crack jokes and play usually harmless pranks on others. Sometimes her pranks or jokes can be mean or rude, but she doesn't seem to realize this until the person she has teased or pranked begins to cry or tells her off for it. Pepper will also use her humor or tricks to try to perk others up when they seem upset. Being a skunk, Pepper hates it when others reference a natural skunk's musk. She isn't normally smelly and it only happens when she is nervous or scared. When she is excited or very happy, she'll release a pleasant smelling scent instead. It's been revealed however that she can also willingly spray if she needs to use it for some reason.
Pepper is an adorable and lovely light gray tomboy skunk with gray coloring inside of her ears. Her muzzle, chest, stomach, back, and tail streak are pure white. Her eyes are a pale shade of pink with a slight red hue. Her hair is a tuft of pale blue-gray bangs.
Despite fans of the show supporting "Sepper" (Sunil/Pepper), Pepper has befriended a squirrel (which Blythe Baxter named "Shivers") after they lead him back to his home when they promised to clean it out after he stole the pet's stuff. She has also fallen in love with a Polecat European Polecat named Captain Cuddles in the episode "Sweet Pepper".
