I think Solaire of Astora from Dark Souls would be a great character to focus on. If he were to cross over into the Miraculous Ladybug world, his unwavering faith and chivalrous nature would make him stand out. He could interact with Ladybug and Chat Noir in unique ways, perhaps teaching them some of his combat techniques or his way of seeing the world. And in the Dark Souls world, his reaction to the colorful and more 'light - hearted' heroes from Miraculous Ladybug would add an interesting dynamic.
Ladybug would be very interesting. Her positive and creative approach in Miraculous Ladybug would contrast greatly with the dark and gloomy world of Dark Souls. She could bring a new perspective to the problems and challenges in the Dark Souls world. Her ability to think on her feet and come up with solutions using her Lucky Charm would be fascinating to explore in a world full of death and despair.
Chat Noir could also be a great focus. His flirty and carefree nature in Miraculous Ladybug would be put to the test in the Dark Souls world. He would have to become more serious and strategic. His cat - like powers could be seen in a new light as he tries to survive in a world full of dangerous creatures. His relationship with Ladybug might also change as they face more extreme challenges together in this crossover.
I think Ladybug would be the most interesting. At the masquerade ball, she has to maintain her secret identity while also enjoying the event. She might be on the lookout for any signs of trouble, all while looking elegant in her ballgown and mask. It would be exciting to see how she interacts with other characters without giving away who she really is.
I think Marinette would be really interesting. She's already so flustered around Adrien, and at a school dance, her nerves would be on high alert. Plus, she has to keep her identity as Ladybug a secret, so if any akuma - related stuff happens during the dance, she has to find a way to balance being a normal girl at the dance and a superhero. It would be fun to see how she handles all the different emotions and situations.
One possible plot could be that Ladybug and Chat Noir are somehow transported to the Dark Souls universe. They find themselves in a desolate and dangerous land, facing powerful enemies they've never encountered before. Ladybug's Lucky Charm ability might work in strange ways, like creating items that have a different use in the Dark Souls world. Chat Noir could use his cat - like agility to navigate the treacherous terrains. Together, they have to find a way back home while also uncovering the secrets of this new and menacing realm.
The interaction between the kwamis and Alfred would also be great. Alfred, being the wise and calm figure in Batman's world, would be very curious about these little magical creatures. He might offer them some tea and biscuits while asking them about their powers. The kwamis, on the other hand, could be fascinated by Alfred's skills in taking care of the Batcave and helping Batman.
Ladybug would be really interesting. When she switches to Cat Noir's miraculous, she has to step out of her usual role of being the organized and strategic one. Seeing her adapt to Cat Noir's more spontaneous and flirty nature could create a lot of humorous and character - building moments.
Definitely Chat Noir and Iron Man. Iron Man's high - tech gadgets and Chat Noir's acrobatic skills and cat - like reflexes would make for a great combination. They are both a bit of a flirt too, so there would be some really fun banter between them while they're fighting side by side.
Ladybug and Iron Man could be really cool. Iron Man is a tech genius, and he might be super intrigued by Ladybug's magic - based powers. He could try to analyze her Miraculous while she shows him that there are things technology can't fully understand. And Cat Noir with Black Widow would be a fun pair. Black Widow's stealth and combat skills combined with Cat Noir's acrobatic abilities and his cat - like reflexes would make for some great action scenes.
Ladybug and Chat Noir are obvious choices. Their dynamic is always interesting to explore further. You can show how they grow and develop as heroes. Also, the Puppeteer herself is a great character to focus on. Her motives and powers make her a complex character that can be delved into deeper in fanfiction.
Chat Noir is also very interesting. His flirty and carefree nature could be a contrast to the seriousness of the Prime Queen threat. Maybe he tries to use his charm to distract Prime Queen or to get information out of her. And his loyalty to Ladybug could be explored more deeply during this event.
I think Chloe could be really interesting. Since she was Miracle Queen, exploring her motives and her internal struggle would add depth to the story. Maybe she wasn't fully in control when she became Miracle Queen and there's more to her actions than meets the eye.
