Sonic Fanon Wiki

Compared to her twin sister Jayme, Amy Acorn, better known as Swift, is a natural athlete. Born to Sally Acorn and Monkey Khan, she isn't exactly her mother's favorite daughter, although she doesn't care, saying "I was born to run, and nobody can stop me, even my mum!"


Swift appears in Flashfire212's Book Two: The Sickness onwards.

Forms and Fusions

Like her mother, none.


Swift looks like her mother and sister, but wears a green mini-skirt and singlet for comfort while running.


Swift is one of the fastest Mobians around, only being regularly beaten in races by people like Manic and Sonic, the fastest beings on Mobius. She is able to accelerate at similar speeds to Manic, but cannot hold a similar pace to him in a short distance, requiring time to build up momentum. In a long distance, she is VERY hard to beat, with even Sonic admitting she was talented. In combat, Swift is powerful, especially with her kicks and dodges, anything that requires leg strength. After Will's surgery, she has him train her in combat, and she eventually learns how to control air currents and the wind using Chaos Energy, which she stored by converting both chemical energy (the energy she normally burned off by running) and kinetic energy (from her running) into Chaos Energy when she needed it. She would also run in circles to create whirlwinds and tornadoes, both of which she uses to her advantage. She has a Wind-type affinity in Chaos Energy.
