Achilles Heel

Achilles Heel is the femslash ship between Pyrrha Nikos and Cinder Fall from the RWBY fandom.

Canon
Cinder and Pyrrha never spoke to each other in Volume 2, it is clear that Cinder has some unknown plans for her, telling Emerald to add her to "the list". She also had Mercury fight against her in chapter 5 to gage what her semblance was. When mercury told her about it, Cinder seemed to be impressed by Pyrrha's Semblance.

In "End of the Beginning", Cinder and Pyrrha fight against each other at Beacon Tower. Although Pyrrha put up a valiant fight, Cinder ultimately defeats her by shooting Pyrrha in the heel with an arrow. She then taunts Pyrrha, saying that the Fall Maiden's power never belonged to her, and that she would make better use of it's powers.

Before she can finish her off though, Pyrrha asks Cinder if she believes in destiny, to which Cinder responds "yes". Cinder then ends Pyrrha's life by shooting an arrow into her chest and then subsequently disintegrates her. In Volume 6 chapter 13, Cinder quotes Pyrrha's last words to Neo to prove that she still believes in destiny.
