Pillnus can shoot numerous metal chains out of her body at will, which are used to bind her targets and render them helpless. She is possessed of sadistic cruelty, taking extreme amusement in the pain of others; especially enjoys torturing Renais Kerdif-Shishioh and Soldato J, taunting them about their apparent inability to completely defeat her. Pillnus also likes to create pet names, calling Pia Decem "Death-y" and Renais "my kitty".
