He's very useful in battle, especially since his Jump attack causes him to avoid a lot of nasty stuff. I really like how vulnerable he was, despite his 'bad ass dragoon' deal. His jealousy of Cecil, his feelings for Rosa, all very human aspects and very neat to deal with. I also like how, at the end, he (SPOILER)goes out on his own instead of going back with everyone else, to atone for his sins. Very cool.
