One idea could be Ruby discovers she is the Winter Maiden in a moment of great danger. As she tries to control her new powers, she has to face off against Salem's minions who are after the power of the Maiden. Ruby's friends, Weiss, Blake and Yang, are initially shocked but quickly support her in her new role.
One great RWBY Winter Maiden fanfiction is 'Winter's Ascent'. It delves into the backstory of the Winter Maiden, exploring her training and the internal struggles she faces. The author does an excellent job of depicting the RWBY universe's lore within the fanfiction.
Ruby could start having strange dreams related to the Winter Maiden's power before she actually becomes it. These dreams could be a foreshadowing of her future role. Once she becomes the Winter Maiden, her silver eyes might interact with the Maiden's power in a unique way, perhaps enhancing it or giving it a new aspect.
One possible aspect to consider in this fanfic could be the implications on Penny's relationships. Since she becomes a real girl, her interactions with Ruby and the others might change. For example, she could experience more complex emotions and form deeper bonds. Also, the way she views herself and her purpose in the RWBY world would likely shift. She might start to question her place among the humans and Huntsmen more deeply.
Penny would also have to adapt to the concept of time management in human society. In her robotic form, she could operate continuously, but as a human, she'd need to rest, eat, and sleep. This would mean learning to schedule her day around these new necessities.
Of course, there's also the possibility of Penny interacting with characters like Professor Ozpin. Ozpin is a knowledgeable figure in the RWBY world and could provide Penny with advice on her new existence as a real girl. And then there are the villains. If the fanfic has a plot where Penny's new state is a target or a threat to the villains, they would also interact with her in some way, like trying to capture or manipulate her.
One popular theme is the power struggle. The Winter Maiden has a great amount of power, and many fanfictions explore how different characters either try to gain control of it or protect it from others. For example, in some stories, villains scheme to steal the Maiden's power.
It's interesting because of the potential character dynamics. Glynda is a more experienced and strict character, while the Winter Maiden might be younger and more inexperienced. Their relationship could develop in many ways, like a mentor - mentee relationship or a partnership of equals as the story progresses.
She would experience a whole new range of emotions. As a real girl, Penny would no longer be limited to pre - programmed emotional responses. She could feel love, sadness, and anger in a much more profound and complex way. This would change how she interacts with others, especially those she cares about like Ruby.
Well, Penny is obviously one of the main characters. Since the fanfic is about her becoming a real girl, she will be at the center of the story. Then there are likely to be the other members of Team RWBY - Ruby, Weiss, Blake, and Yang. They could play important roles in helping Penny adjust to her new life as a real human.
