I bet full power Vasto Lorde is as powerful as Mugetsu.
Nah, thats impossible. Mugetsu is a transcedent being, far surpassing the limits of hollows.
Its implied that VL is just a fraction of mugetsu's power
And mugetsu is only a fraction of current ichigo's power
And Ichigo's full power is only a 2% of Kenpachi's true power.
