Amy Rose

How Amy joined the Tourney
Amy Rose, also formerly known as Rosy the Rascal, is a fictional, anthropomorphic pink hedgehog from the Sonic the Hedgehog series. She has a major long-standing crush on Sonic the Hedgehog, and has been trying to win his heart by any means since meeting him. Such methods included impressing him by fighting robots, and threatening to leave him locked in prison on Prison Island. Introduced in the game franchise in 1993, Amy was the first — and most recurring — female character in the Sonic the Hedgehog series and is also one of the most popular characters, coming in fifth place on an official popularity poll, being the most popular female character.[3]

She was described to be eight years old in Sonic CD, but from Sonic Adventure onward she has grown by four years. With the addition of Cream the Rabbit, Amy seems to have found herself a sidekick similar to how Tails is to Sonic (as implied in Sonic Battle, Sonic Heroes, Sonic Advance 3, and Shadow the Hedgehog).
