Sonic the Hedgehog (character)
Personality: Amy was once presented as being kind and sweet (and slightly naive.) In more recent games she has become more violent and aggressive. However, she is extremely protective of her friends, and if a bad guy tries to hurt them, she will use all her skill to defeat the bad guy. Despite her violent tendencies, Amy has a very good heart, she never gives up, and she is the most optimistic and cheery character of the franchise. She really cares about her friends, and helps them reach their goals.
