Well, in a Victorious and iCarly crossover fanfiction, the characters could have a big concert together. Tori from Victorious and Carly from iCarly might team up to put on a huge show. They could combine their unique talents, like Tori's amazing singing and Carly's great hosting skills.
One possibility is that the characters end up in a wacky competition. Maybe it's a battle of the web shows. The Victorious gang and the iCarly crew could compete in various challenges, such as who can get the most views in a day or who can come up with the funniest skit. It would be full of humor and friendly rivalry.
One possible plot could be that the characters from iCarly and Victorious end up at the same event, like a huge music and web - streaming convention. Carly and Tori might start off as rivals, competing for the best performance slot. But then they realize they can collaborate. Sam and Jade could get into some comical arguments. Freddie could use his tech skills to help the Victorious gang with their production needs. And in the end, they all put on a combined show that's a huge hit, and they become friends.
I think Carly and Tori would be really interesting. Carly is used to running her own web - show and has a very DIY approach. Tori is more into traditional performing arts. When they come together, there could be a clash of ideas at first. For example, Carly might want to use a lot of home - made props and simple camera setups, while Tori is used to the grandeur of the Hollywood Arts stage. But they could also learn a lot from each other. Carly could teach Tori how to connect more directly with an online audience, and Tori could introduce Carly to more formal performance techniques.
Carly and Jade could be really cool together. Carly is sweet and friendly, while Jade is edgy and a bit of a troublemaker. Their interactions would be full of contrast. Carly might try to soften Jade a bit, and Jade could introduce Carly to a more rebellious side of life in Hollywood Arts.
In this fanfiction, perhaps Sam's sickness is something really unique that no one has ever seen before. It could be a magical or science - fictional kind of illness. Her friends could go on a wild adventure to find a cure, traveling to strange places and meeting all kinds of interesting characters along the way.
One idea could be that the martial arts students from 'Kickin' It' visit Hollywood Arts from 'Victorious'. They could get involved in a big musical and martial arts show. Maybe the characters from 'Kickin' It' teach some self - defense moves to the actors at Hollywood Arts. And in return, the Hollywood Arts students teach the 'Kickin' It' crew some acting and music skills.
One idea could be that Naruto and his friends somehow end up in the iCarly universe. Maybe they're on a mission and a strange jutsu goes wrong, transporting them. Naruto could be really confused by all the modern technology in iCarly's world. He might try to use his ninja skills to help Carly and her friends with their web show, like doing some cool stunts for it. And the iCarly gang could introduce Naruto to things like pizza and video games, which he'd find really strange but fun.
It could be a comical kiss. Given the nature of Victorious, there might be some misunderstandings before the kiss. Like Robbie thinks it's part of a play or something, and Cat just goes for it without really thinking. And then they both get all flustered and embarrassed afterwards, which would be really funny to read about.
One possible plot could be that Carly and her friends are doing a webcast about unique families, and they decide to interview Drake and Josh. Hilarity ensues as the iCarly gang tries to get Drake and Josh to do some of their crazy webcast stunts. Meanwhile, Megan gets involved and plays some pranks on both the iCarly crew and Drake and Josh, creating chaos but also some really funny moments.
Luffy from One Piece would be a great crossover character. His carefree and determined nature would contrast well with Naruto's own. They could both bond over their love for their friends and their strong wills. Another good character could be Harry Potter. Imagine Naruto in the wizarding world, and he and Harry could exchange knowledge about their respective magic systems, with Naruto showing off his ninjutsu while Harry demonstrates spells.
One common theme is friendship. When characters from different shows cross over, they often form new friendships or strengthen existing ones. Another theme is competition. For example, if it's a crossover between two music - based shows, there might be a singing or performance competition. Also, the theme of discovery is popular. The characters discover new places, cultures or even new aspects of themselves when they cross over into different fictional worlds.
