Carla is a beige dog with long brown hair, and small floppy ears, along with a small, oval-shaped nose. She wears a yellow button shirt, a dark green jacket, a teal skirt, long white socks, and small, dull purple shoes.
Carla is very enthusiastic and joyful. She is polite and kind to everyone, no matter the age. She also likes programming, as shown in "No More Pow Cards". However, it is implied that her programming skills are not on the same level as Dendy as she admits that it would have taken her ages to write the override program Dendy created to make the Hero Computer recognize Kappas. She recognizes Dendy's skill and was happy to allow Dendy to run her program after checking it. While she was suspicious of Dendy's program at first, she checked the program to ensure it did not do anything malicious, however, this may have simply been to ensure that Dendy's program could do exactly what Dendy said it could do, showing due diligence on her part.
In "Dendy's Power", she is shown to live and work in The POW Card Industries Cloud Server. She is shown to be easily frightened as she hid inside the server when she learned the server was being attacked by the Shannon virus and was thankful towards Dendy and K.O. for defeating her, repaying them by fixing K.O.'s POW Card glitch.

- Her cheerful personality, quirky demeanor, and overall design might have been inspired by Isabelle from the Animal Crossing series.
