Aeris is a mysterious young woman that Cloud meets while she is selling flowers on the streets of Midgar. She soon becomes part of an increasingly deepening love triangle between herself, Cloud and Tifa.
Aeris has unusual powers that enable her to use magic better than the other characters, however her physical strength is lower as the trade off. Aeris uses a staff to attack but she is much more suited to magical attacks. The best weapon Aeris has access to is the Princess Guard, which as far as I know powers up whenever Aeris protects someone in battle. Her best limit break is Great Gospel.
