I think Luna from the Loud House would be really interesting. She has that rocker vibe which could mesh well with the spooky and unique nature of the ghouls. And then there's Spectra Vondergeist from Ghoul School. She could use her ghostly abilities to have some cool interactions with the Loud kids. Maybe she could play pranks on them that are more friendly than scary as they get to know each other.
I think Lincoln would be the most interesting. He's used to handling a big family and all kinds of chaos at home. In the Kingdom Hearts universe, he could use his adaptability and problem - solving skills. He'd be curious about the new worlds and the magic there, and his journey of discovery would be really engaging to read about as he teams up with Kingdom Hearts characters.
Well, perhaps the ghouls from Ghoul School are on a field trip to the human world and end up in Royal Woods. They meet the Loud family and chaos ensues at first as the Loud kids are scared. But then they realize the ghouls are friendly. Together, they have to figure out how to get the ghouls back to their school before the sun rises, which is dangerous for the ghouls. And along the way, they learn about each other's cultures and make new friends.
Definitely Uta from Tokyo Ghoul. His mysterious nature and his skills as a mask - maker would bring a lot of intrigue. Also, Haruka Nanase from Uta no Prince - sama could be interesting. Imagine his pure and kind - hearted personality being exposed to the dark and dangerous world of Tokyo Ghoul. The contrast between them could create some really engaging storylines.
Leni could be a fun character to center around. Since she's not always the brightest, a message that she misinterprets in her own unique way could lead to all kinds of humorous situations. For example, if the message is about a fashion show, she might think it's something completely different and start preparing for a very strange event.
I think Spongebob and Lincoln would be really interesting. Spongebob's wacky optimism and Lincoln's attempts to navigate his crazy family life could create some really fun and comical situations. They could learn from each other - Spongebob about family unity from Lincoln, and Lincoln about pure joy and simple living from Spongebob.
I think Lincoln Loud would be really interesting. He's used to dealing with a big family and all kinds of situations at home. In the Spyro world, he could use his problem - solving skills to help Spyro on his quests. His curiosity would also make him eager to explore the new world of Spyro.
I think Lincoln would be really interesting. He's used to dealing with a big family in The Loud House, so in Sword Art Online, he could use his leadership skills to form a guild with the other characters. His ability to adapt to different situations at home would come in handy in the dangerous world of SAO.
For me, it would be the Nine - Tails from Naruto. Imagining how the giant, powerful fox would be perceived in the Destiny universe, where there are all kinds of strange and powerful creatures, would be really cool. And from Destiny, the Exo Stranger. Her mysterious nature and time - traveling abilities could add a lot of intrigue to the crossover. Another interesting character to focus on could be Sakura. Her growth as a medical ninja and her combat skills could be useful in the Destiny setting, and her relationship with Naruto and Sasuke could bring in some interesting character dynamics.
Sebastian would be really interesting. His demonic nature and his ability to adapt to different situations in 'Black Butler' would make him stand out in a crossover. He could use his skills to either help or manipulate the characters in 'Tokyo Ghoul'. His loyalty to Ciel in his own series could be contrasted with his new relationships in the 'Tokyo Ghoul' world, and it would be fascinating to see how he uses his powers to deal with ghouls.
I think Lincoln Loud would be really interesting. He's used to dealing with a large family and all kinds of chaos at home. In the Tokyo Ghoul world, he would have to use those skills to survive among the ghouls. His sense of curiosity and determination could lead him to try and understand the ghouls better, and he might even try to find a way to bridge the gap between humans and ghouls, which is a major theme in Tokyo Ghoul.
