She can one hit any land based machina except the guardians, and eventually becomes equal in power to tidus, just ever so slightly slower (or maybe she was the faster one...) . She can use her combine limit to fully heal the party and make it invincible, or to warp enemies, create explosions, etc. She can use steal, and mug, and is the only one who can loot background chests. I believe there is a boss that has a charging attack that if she uses steal on it will negate the charge attack. (may be different game) Also she has that awesome sweater.
