In J. M. Barrie’s Peter Pan, the fairy who becomes jealous of Wendy is Tinker Bell.
Tinker Bell is Peter Pan’s fairy companion and one of the story’s most important supernatural characters. Her jealousy arises because Wendy receives Peter’s attention and becomes part of his adventure with the Darling children.
Barrie presents Tinker Bell as passionate, impulsive, and capable of both loyalty and harmful decisions. Her small size is central to the story’s imagery, while her speech is represented through sounds that humans cannot understand directly.
Disney’s 1953 animated film made Tinker Bell a silent, highly recognizable visual character, but Barrie’s original Tinker Bell speaks in a fairy language. The character’s name is sometimes shortened to “Tink” in adaptations and fan usage, but Tinker Bell is the canonical name.
