I kind of feel Rouge would be the kind of character with shorter knives that would be great for combos (and like little extended knives that come out of the top of her boot... probably doesn't go with the golden axe aesthetic but it's what I picture) then larger swords but outfit and pose especially with the earrings does really work well for her.
