Pinky is a main character in the animated series Pac-Man and the Ghostly Adventures. She is a pink ghost with long hair and pink eyes, and she is both the shortest member and the only female member of her ghostly group. Following the events of the first episode, she becomes one of Pac-Man's ghostly allies, joining Blinky, Inky, and Clyde as a friend of Pac-Man rather than an opponent.

In terms of personality, Pinky is generally sweet and flirty, though she can become quite angry on several occasions. She usually spends her time with Blinky, Inky, and Clyde, and she has a strong crush on Pac-Man. This affection influences much of her behavior and her view of others: she regards Cyli as a rival for Pac-Man's attention, while Cyli in turn views Pinky as somewhat ditzy. Despite this, Pinky remains a loyal and caring companion to her friends and is willing to stand alongside Pac-Man when danger arises.

Her main motivation is her devotion to Pac-Man and her desire to support him, as well as her loyalty to her fellow ghosts. In the story, she serves as one of Pac-Man's core allies in the ongoing conflict against Betrayus and the Ghostly Host, using her ghostly abilities to help defend Pac-World.

As a ghost, Pinky possesses the typical traits of her species: she is a spectral ectoplasmic entity that can levitate, pass through objects, and leave trails of ectoplasm. She also demonstrates a degree of body manipulation, such as being able to reshape herself to resemble a Cyclops ghost even though that is not her natural appearance. Her development across the series centers on her transition from an adversary to a trusted friend, with her crush on Pac-Man and her spirited personality remaining consistent parts of her character.
