In J. M. Barrie’s Peter Pan story, the fairy who helps Peter fly is Tinker Bell.
Tinker Bell is Peter Pan’s fairy companion and a major figure in the Neverland story. Barrie presents her as small, energetic and jealous of Wendy’s closeness to Peter. Her communication is described through the sounds of bells rather than ordinary human speech.
In the stage play and later adaptations, fairy dust became closely associated with flying. Barrie’s original story also links flight to happy thoughts, with fairy assistance helping the children reach Neverland. The exact rules and visual appearance of fairies vary among adaptations.
Disney’s 1953 animated film made Tinker Bell one of the most recognizable characters connected with Peter Pan. However, the character originated in Barrie’s earlier stage and literary works, not with Disney.
