Iron Maiden

Iron Maiden is the het ship between Penny Polendina and James Ironwood from the RWBY fandom.

Canon
Penny is seen standing with Ironwood and a group of other Atlesian military personnel in the Volume 2 Opening of Rwby. He is then revealed later that volume, to have assisted and sponsored her father in her creation, with the hopes that she will one day be able to save the world. Penny is also seen following Ironwood around in volume 3, chapter 3.

In volume 7 chapter 12, after Penny along with Winter heard Ruby's warning about Ironwood's plan to abandon Mantle, she seems very disturbed and shocked about his plan. After Penny becomes the new Winter Maiden, she decides to abandon Ironwood and sides with Ruby and her friends.

In volume 8 chapter 1, Penny gets a call from Ironwood. She answers his call where she hears him ask her to return to Atlas only for Ruby to take her scroll and answer back she isn't going anywhere until he changes his mind about Mantle. She becomes visibly distraught when he says that if Salem gets through Atlas' defenses, everything that follows will be her fault, and Ruby comforts her.

In "Refuge", she explains to Ruby how Ironwood's words were weighing on her, saying that people would die because of her. Ruby then says ironwood was only trying to hurt her and reassures her she made the right decision.
