Amy Rose

 Amy "The Rascal" Rose" is a heroine from the Sonic the Hedgehog series. She is madly in love with Sonic and wants him to marry her which is odd because she is 11. She carries around a large hammer called a Piko Piko Hammer for a weapon.

Her story
Her first appearance in the games was in Sonic CD, introduced and kidnapped by Metal Sonic, although she was alluded to "Princess Sally" in the Western game manuals, in order to tie in with the cartoon.

After this appearance, she became known as Amy. Her first playable appearance was in Sonic Drift, although that game was not released outside of Japan, making Sonic Drift 2 her first playable game for other regions. Not possessing the speed or strength of other characters, Amy uses a "Piko Piko Hammer" as a weapon.

Personality and abilities
Amy has a cheerful, exuberant, driven, competitive and intuitive personality. She is infatuated with Sonic the Hedgehog and spends a significant amount of time chasing him making sure he is safe and seeking romantic advances on him.

While Sonic does not reciprocate her strong affection and is rather annoyed by it to the point of avoiding her at all costs, he does not truly dislike her in his heart.

Yuji Naka, former head of Sonic Team, has stated that Amy's design is "to always chase Sonic" and that—despite frequent questions from fans—it is unlikely the two will ever get married.

Like most characters in the Sonic series, Amy can run at superhuman speeds, though not as quickly as Sonic.

She attacks foes mainly with a variety of maneuvers of her Piko Piko Hammer which she is very proficient with and never leaves her home without. She also possesses supernatural skills: she is skilled with tarot cards and dowsing.

Sonic Boom
Instead being in love with Sonic (which she does, but she's not the old Amy in the other series), she's an older and mature woman and what she doesn't know that Sonic had a secret crush in her (hint on Sonic Boom: Rise of Lyric cutscene, it hints that Sonic does have feelings for Amy (standing in an elevator not knowing what to say to Amy).
