>>2331659As I understand it the power hierarchy is
Hybrid+Hybrid(Ryuko+Senketsu)>Hybrid+Pure Life Fiber(Ragyo+Junketsu/Koketsue)> Pure Life Fiber(OLF)>Hybrid(Nui)
Nui is the strongest of all hybrids, but the fact that she can only fight by herself makes her a failure as a weapon.
This is just speculah, but I'd like to believe that world of Life Fibers is what Ragyo wanted, and that's why she worked on creating hybrids, it was her way of "saving" humanity.
