What are some interesting plot ideas for 'heaven's lost property crossover fanfiction'?

One idea could be a crossover where the Naruto characters end up in the world of Heaven Lost Property. Naruto's skills in combat and his determination could create some really cool scenarios when faced with the angels and devils in that world.

Another interesting plot could be that the world of heavens lost property gets merged with a parallel universe where the rules are slightly different. The characters would have to adapt to the new situation, and there could be new villains or challenges. For instance, the Angeloids' powers might work differently, and they would need to figure out how to use them effectively. Tomoki would also have to deal with a version of himself from the other universe, and they could either cooperate or compete depending on the circumstances.

In a crossover with 'Fate/stay night', characters like Saber could be included. Her noble and strong - willed nature would contrast with the more carefree and sometimes naive angeloids. They could be on a quest together, with Saber's combat skills and the angeloids' unique powers complementing each other.

One idea could be that Naruto somehow gets transported to the world of Heaven's Lost Property. He might mistake the Angeloids for some new kind of summon or ninja tool. He could then try to befriend them and use their powers in his own way, like how he befriended Kurama. Maybe he would teach them about ninja values like loyalty and perseverance.

One idea could be a crossover with 'Buffy the Vampire Slayer'. The two strong female leads from each show could team up to fight a common supernatural enemy. Maybe they meet in a dimension where both their worlds collide.

One interesting idea could be the unique character interactions. For example, how the RWBY characters might interact with the denizens of 'heaven' in this fanfiction. Maybe they learn new skills or gain different perspectives on their own world.

One idea could be to cross it with a superhero universe. For example, a character from 7th heaven could gain superpowers and have to navigate their new life while still holding onto their values from the show. This would create an interesting dynamic as they balance their normal family life with their newfound abilities.

One idea could be Naruto being transported into the Heaven's Feel world and having to deal with the Grail War using his ninja skills. Another could be a crossover where the characters from Naruto interact with the Heaven's Feel characters in unexpected ways, like Naruto befriending Shirou and teaching him some ninja techniques.

Sasuke and Nymph could be a great pair. Sasuke is brooding and powerful, and Nymph is sassy and has her own set of abilities. The contrast between them would create a lot of tension and interesting dialogue. Sasuke might be intrigued by Nymph's powers and her non - ninja way of doing things. And Nymph could be interested in Sasuke's cool and mysterious demeanor.

One idea could be that the Turtles from 1987 end up in the 2003 universe and have to adapt to the darker and more serious tone. They could team up with the 2003 Turtles to fight a common enemy like the Shredder. The 1987 Turtles' more light - hearted and comical ways might initially clash with the 2003 Turtles' brooding nature, but they eventually learn from each other.
