Noelle and Vivi both have powers that look very similar. The actual abilities work in fundamentally different ways but they have the same effects which is really what is the focus here. It’s interesting to see these characters as parallels since even their personalities are similar. Noelle had much more time to gain power ups and experience though to the point where they are really in different leagues. Noelle should be able to easily out speed Vivi at this point. Noelle wins.
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.
