This is a prior allusion that's already well-known but I'll mention it already: Pyrrha was based of a Greek warrior, specifically Achilles. Achilles was invincible except for a small section of his foot, and that's how he ended up dying. Cinder injured Pyrrha with an arrow to the heel before killing her.
