One idea could be that Winnie discovers a hidden part of the hotel that no one else knew about. It could be filled with ancient artifacts or magic that she then shares with the other characters. Another idea is that Winnie has a special power that she doesn't know about until she comes to the Hotel Transylvania, and the other characters help her learn to control it.
One storyline could be that Dennis and Winnie go on a secret adventure outside the hotel. They discover a hidden magical garden filled with strange and wonderful creatures. Dennis, being part - vampire, uses his unique abilities to protect Winnie when they encounter a slightly dangerous but ultimately friendly magical beast. They learn about the importance of friendship and bravery in this new world they've found.
In a fanfiction of Dennis and Winnie, perhaps they decide to explore the outside world. Winnie, being a vampire, has to protect Dennis from the sun. They meet some friendly humans who are surprisingly accepting of them. Dennis starts to realize that he can be a bridge between the human and vampire worlds. They have a lot of fun, like trying human food for the first time and sharing vampire stories with their new friends.
Well, a fanfic about Winnie and Dennis in Hotel Transylvania 2 could be really interesting. It might explore their relationship as they grow up in the monster world. Maybe they could have adventures together, like exploring the hidden parts of the hotel that are off - limits to most guests.
One idea could be a story about a new character who arrives at the hotel during the events of the third movie. This character could have a special power that both helps and causes chaos among the hotel guests. For example, they might be able to communicate with sea monsters in a unique way, leading to some hilarious misunderstandings.
One idea could be a fanfiction about Mavis and Dracula going on an adventure together to discover a new magical place for the hotel. This would focus on their relationship and the expansion of the hotel's world.
There might be some family - friendly fanfiction out there. Some fans may create stories that focus on the adventures of the characters from Hotel Transylvania and perhaps include a character named Winnie in a non - inappropriate way. For example, they could write about Winnie making new friends among the Hotel Transylvania residents, or going on a fun exploration around the hotel with the other characters. However, it may take some searching through fanfiction websites to find such stories.
Maybe there's a misunderstanding between Dennis and Winnie. Winnie thinks Dennis is too focused on his human side, and Dennis thinks Winnie is too stuck in the old vampire ways. But then a new threat comes to the hotel, like a group of hunters. They have to work together to protect the hotel and its inhabitants. In the process, they understand each other better and their relationship deepens.
In a fanfiction, perhaps some of the Hotel Transylvania characters could have chakra. Mavis, for example, could discover she has a special type of chakra that gives her the ability to control bats in a new way. She could then go on a journey to the Naruto world to learn more about chakra and meet characters like Kakashi who could teach her about different chakra natures.
One great idea for a 'Hotel Transylvania Invisible Man' fanfiction could be to focus on how the Invisible Man interacts with the other monsters in the hotel. Maybe he plays pranks on them by using his invisibility in funny ways, like moving objects around without being seen. It could be a light - hearted story full of comical misunderstandings.
Another idea is that the OC is a half - human, half - monster who is rejected by both communities. Dracula takes pity on the OC and offers them a place at the hotel. However, the other monsters are not so welcoming. Dracula has to fight against the prejudice of his own kind to protect the OC. In the process, the OC shows great courage and loyalty, which makes Dracula see them in a new light, and a deep friendship or even a romantic relationship could develop between them.
