Well, this kind of fanfiction often explores unique concepts. It might involve the character from RWBY being reborn as Penny. Maybe it'll show how the character adapts to Penny's life, her abilities and relationships. It could also bring in new storylines that are different from the original RWBY plot.
Ruby would be an obvious choice. Since they are both friends in the RWBY series, a crossover could explore a deeper bond between them. Maybe they go on a special mission together that takes them to a new and dangerous part of Remnant. Another good character could be Weiss. Their different personalities and fighting styles would create interesting interactions. Weiss' ice powers combined with Penny's technological abilities could make for some cool combat scenes.
In the 'rwby penny fanfiction' world, 'Penny's Redemption Arc' is quite popular. It delves into Penny's character more deeply, exploring her past mistakes and how she overcomes them. It's a great read for those who want to understand Penny on a more profound level. There's also 'Penny's Friendship Chronicles' which focuses on Penny's relationships with the other characters in RWBY, showing her growth through these connections.
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.
Penny's return can add a new layer of hope to the storyline. Her presence can boost the morale of the RWBY team. For example, if they were in a tough battle and losing hope, her return could change the tide.
In RWBY fanfic, Penny and Ruby often have a very special relationship. Ruby is generally portrayed as being very friendly and accepting towards Penny. Penny, being an android, is in some ways an outcast, but Ruby sees her as a true friend. Their relationship can be seen as a symbol of acceptance across differences in the RWBY universe created by fanfic writers.
One possible theme could be self - discovery. As the character is reincarnated as Penny, they have to figure out who they are in this new form. Another theme might be friendship, as they interact with the other characters in the RWBY world as Penny. Also, the theme of adaptation, since they need to adapt to Penny's abilities and the situation she is in.
Well, there are quite a few good ones. For example, some fanfictions might put Ruby and Penny in a situation where they have to team up against a new and powerful enemy that the main RWBY plot hasn't introduced yet. This could show their combat synergy and how they support each other in battle. There could also be fanfictions that delve into their backstories more, like Penny's early days as a synthetic being and how Ruby might have reacted if she knew about it from the start. Some might even have a more light - hearted approach, like them going on a shopping spree in Vale and the comical situations that ensue.
In many RWBY fanfics, Penny as a real girl often means exploring her newfound humanity more deeply. She might experience emotions in a more complex way. For example, she could struggle with the concept of friendship and loyalty on a more emotional level, rather than just following pre - programmed responses.
