For a cat with a dramatic stare, stealthy paws, or a talent for gentle chaos, a sinister-sounding name can be a fun fit. Browse ideas by style—from fictional villains and mythology to supernatural names, gangsters, and famous cats—and choose one that suits your cat without taking the word “evil” too seriously.
“Evil” is a playful naming mood, not a judgment about a cat’s character. One Reddit poster captured the joke with a request for an “EVIL kitten” who “purrs when she chews on me.” That anecdote is one person’s description, but it points to the appeal: a grand, villainous name can be funny on a much-loved pet.

Fictional villains: bold names with instant drama
Choose a villain-inspired name if you want a familiar character reference or a theatrical sound. These examples include names highlighted in Catster’s collection; the associations below identify their well-known fictional contexts.
- Bane: the formidable Batman adversary, with a short, forceful sound.
- Bellatrix: Bellatrix Lestrange, the villainous witch in the Harry Potter stories; a dramatic option for a cat with an imposing air.
Mythological figures: a grand, legendary feel
Mythology offers names that sound ancient or powerful, but traditions and meanings vary. If a particular figure or tradition matters to you, check a reliable specialist source before choosing a name based on a claimed meaning or role.

Demon and devil names: overtly spooky choices
For a name that leans into the supernatural joke, consider Lilith, an example included in Catster’s list. The name has different meanings and associations across traditions, so it is best not to assume it has one universal definition. You can also favor the sound of a spooky name without attaching a specific religious or cultural meaning to it.
Gangster-inspired names: a tiny boss in the house
A gangster-style name gives a cat a tough persona with a wink. Capone, another Catster example, refers to the historical American gangster Al Capone. It can suit a cat who seems to run the household, though the reference is to a real person rather than a fictional villain.

Famous cats associated with villains
A cat’s name can borrow its sinister mood from a memorable fictional feline. Azrael is one example in Catster’s collection: the cat belonging to Gargamel in The Smurfs. It offers a feline reference without naming your pet after a human villain.
