While growing up, Amalie actually used to be quite nice. She has a sister, 3 years younger, who she actually used to be friends with. However, something tragic soon happens, an accident that results in her losing the use of her legs and making her wheelchair bound. For what she thought may be the rest of her life.

To her family, it seems like she just went missing, but to her she was offered the chance of a lifetime. One day, after leaving home to go for a 'walk', she meets up with a mysterious Scientist. Doctor Eggman. He had the promise of her being able to walk again, which of course she took, why would't she? The Hedgehog would return home, age 15, now walking again, a miracle really. Amalie would soon spend time asking the others their opinions on things, like having robotic limbs, and other robot-related questions... But, well, nothing too specific really. Bunnie Rabbot was the only Mobian she truly opened up to, revealing her own robotic legs, confiding in the fact that well someone helped her walk again.

A year passes, finally she stops pretending. Amalie reveals her true intentions, she was secrely evil all along. How awful! Doctor Eggman was attacking, as he usually did, Sonic called her up to help. This was her chance... And, well, she took her own way. Instead of helping the Blue Blur, she went against him, kicking him down and being quite enough of a distraction to stop him from taking Eggman down instantly.

Amy Rose: Younger Sister. Quite dislikes her, the two seem to have a rivalry of sorts, not helped by Amalie becoming a Villain.

Sonic the Hedgehog: Enemy. She doesn't see why her sister likes him so much, he really isn't a great person. She dislikes him and enjoys any chance she gets to fight him.

Doctor Eggman: Ally. The two don't always work together, but occasionally she will work on his side if it is required. As long as he keeps out of her way, she won't try fighting him.

• Her legs appear to be immune to anything, a benefit from them being robotic now. She also can't get ill at all, something she finds very handy since it lets her fight for as long as she wants.

• Super Speed. Spindash. Homing Attacks. Powerful Kicks. Robotic Skills. Martial Arts.
