Monado III

The Monado III is the weapon earned by Shulk during the final battle against. It replaces whatever Replica Monado he has equipped and cannot be removed. It is equal in power to the Monado II, making it stronger than all the Replicas, and has by far the highest crit rate of any weapon - enough that when combined with other effects, it becomes possible to achieve a crit rate of 100%. The player keeps the Monado III after starting even if Shulk would usually wield the Junk Sword or any other type of Monado or Replica Monado. That also means that it is impossible to use Turn Strike after the first playthrough.
