Amanda was born in Maine. Being a fairlie, she had special abilities other humans didn't have. In her case she can levitate objects, persons or herself. When the military started studding, she was sent to a special house. However, Amanda escaped with her friend Jess and went to Orlando, where they lived in an abandoned church. Here she teamed up with the Kingdom Keepers and helps them in their duty to save the magic from the parks.
As the story progresses, her relationship with Finn becomes mutually romantic. However, due to her power to push things away leaking into her relationships, this accidentally causes her to distance herself from him at times; Finn laughs at the problem, considering himself her yo-yo. How strong their love for each other is can be shown with the example that when Finn was put under a spell by the Evil Queen to kiss Jess, ensuring she would sleep forever, and not be able to use the dreams of the future to help the Keepers, his feelings for Amanda caused him to kiss her. Amanda didn't resist the kiss, showing she had been waiting for him to do so, and was later awoken by piercing her finger on a spike of a water wheel. Another example, perhaps as one to show how strong love can be, is that when Amanda had drained herself to hold back a tidal wave Ursula created, Finn's kiss to her cheek gave her energy.
- Amanda's backstory is almost similar to Wolverine, both are super-humans who were experimented on by the military but escaped and later joined heroic groups.
