Suggested by Sonic Ghirahim is fast and his ability to teleport can really come in handy here. The question is, will this be enough to overwhelm someone like Yuna who can shoot out countless kinds of energy blasts and elemental moves? I think Ghirahim will find that to be a very difficult task indeed. Yuna’s main weakness in this fight is her lack of durability but she should be able to shield herself with her monsters and barriers long enough to strike him down. Yuna wins.
