Another plot could be that Christopher Robin brings a new friend from the outside world to the Hundred Acre Wood. Pooh and the others are a bit hesitant at first, but Christopher Robin helps them all get to know each other. This new friend could introduce some new games or ideas to the wood, but also cause a bit of chaos until they all learn to adapt.
One idea could be that Christopher Robin gets lost in the Hundred Acre Wood as an adult and Pooh has to help him remember all the wonderful things from his childhood. They could go on a journey to find the special places that they used to visit together, like the bridge over the stream or the bee tree.
It could be a dark version of Christopher Robin himself from an alternate dimension. This 'evil' Christopher Robin might be jealous of the happiness in the real Hundred Acre Wood and try to disrupt it. Pooh would have to rely on his pure heart and the love he has for his friend to bring the real Christopher Robin back and defeat the impostor.
A cool plot could be that there's a mysterious threat targeting all of Batman's allies. Robin and Batgirl team up to not only find out who's behind it but also to protect each other. Along the way, they share some personal stories from their pasts that bring them closer together.
Some fanfics might explore an alternate universe where their roles are different. For instance, Robin could be a powerful mage like Tharja, and they bond over their shared magical abilities. Or perhaps they are from different kingdoms originally and their relationship has to navigate the politics between the two kingdoms while also dealing with their growing feelings for each other. This can lead to a lot of complex and interesting storylines.
A cool plot idea could be that the child has a unique power that neither Robin nor Raven have. This power could attract the attention of an ancient evil force that was once sealed away. So, Robin and Raven have to team up with their friends to not only protect their child but also the whole world from this new threat.
One interesting 'Christopher Robin fanfic' could be about Christopher Robin's adventures in a modern world. He might discover new technologies and how they compare to the simple joys of the Hundred Acre Wood.
Maybe the OC is from a long - lost island with unique knowledge. Robin is interested in the historical aspects of this knowledge and Nami sees the potential for great treasures. The OC then has to deal with the different personalities of Robin and Nami. Robin is calm and intellectual, while Nami can be feisty. Their interactions lead to a series of adventures and a deepening of their relationships.
One idea could be that Christopher Stratos discovers a hidden ability within the Transformers that allows them to travel to parallel universes. He then teams up with Optimus Prime to explore these new realms and face unexpected challenges there.
One idea could be that Robin gets trapped in an alternate dimension where the villains are in control and Batman has to figure out a way to bring him back. Another could be a story where Batman is injured and Robin has to take on a major villain alone, learning to trust his own instincts more. Maybe a plot where they encounter a new, powerful ally who turns out to have a hidden agenda that threatens Gotham.
A plot idea could be Robin's pregnancy being a surprise not just to her but also to her family. Her family might have different reactions, some being very supportive while others might be disappointed or worried. The fanfic could then show how Robin overcomes these family issues while also dealing with the physical and emotional changes of pregnancy. Or it could be about Robin's pregnancy in a world where she has some sort of special ability or power, and how the pregnancy affects that ability and how she has to protect herself and the unborn baby from those who might want to take advantage of her situation.
One idea could be that the Joker, in his twisted way, tries to 'convert' Robin to his side. He could play mind games with Robin, showing him the so - called 'dark truths' of Gotham.
