What is Tinkerbell's weakness?

Tinkerbell's primary weakness is her vulnerability to feelings of jealousy and insecurity, particularly in her relationships with others, such as Peter Pan and Wendy. This emotional turmoil can lead her to act impulsively or spitefully, which can create conflict. Additionally, as a fairy, she can be physically weakened if someone does not believe in her, as her magic is tied to the belief and faith of others.
