Aeris is a kind-hearted girl who sells flowers on the streets of Midgar. She randomly encounters Cloud at the beginning of the game and soon joins him and the gang on a new path. The Shinra Corporation have been searching for her for most of her life for some reason, so her path will be dangerous.
Aeris' strength is in magic, she is the best magic user in the game. Her normal attacks are very weak so take this into consideration. Her limit breaks are all defensive which can really help your party when in desperate need. Use her as a mage character.
