Vivi has the ability to slice through her opponents with her mercury form and can move through the air at high speeds. Tome can also move quickly with her unique martial arts style but we haven’t seen her have the same kind of feats. Vivi’s gone up against much more powerful opponents and come out on top. It’s just hard to see Tome keeping up here and ultimately she would just fall to Vivi’s power as Tome has no hax abilities that would turn the tides. Vivi (Hungry Joker) wins.
