Round 2 of ideas for Fanfiction I've had, but don't have the skill to write

Kamen Rider Kabuto/Ranma 1/2

Souji Tendo, AKA, Kamen Rider Kabuto is Akane's Cousin. He decides to visit Nerima and hijinks ensue. If this happens after Kamen Rider Kabuto has ended, then the Sasword, TheBee, and Punch Hopper Zectors aren't in use.

Sailor Moon/Precure

A few weeks after Galaxia/Chaos' defeat while watching the news, the girls are shocked to see that there's not only a bunch of teams around collectively known as the Precure, but they've been around for years. This fic would play with the idea that the Veteran Cures actually age with time instead of looking the same age in every Crossover.

Kamen Rider Faiz/RWBY

Most people know about the White Fang, a terrorist group bent on conquering Humanity. What no one knows is that the Fang is secretly being controlled by another Faunus Populated group known as Smart Brain, who have developed Gear that can physically enhance a Faunus' power. One of these Gears gets stolen and ends up in the hands of a Wolf Faunus, Takumi Inui, shortly before his first day at Beacon.

Kamen Rider Hibiki/Dungeons and Dragons

In the realms of D&D, bards mostly act as support and rarely have any combat power. This Changes when the Oni Riders are transported to one of these realms and show their power. (Don't really know that much about D&D Lore myself, just participated in a few one off campaigns, and watched a very funny D&D based movie.)

Kamen Rider Den-O/Dragon Ball

The Crew of the Den Liner are bored with no more Imagin's to fight, so Owner suggests they start working for another group that protects time, the Time Patrol. Thus Kamen Rider Den-O helps Trunks in fixing the damage done by the Time Breakers. I imagine that their reaction to the Ginyu Force Poses, and vice versa, would be hilarious.

Haruhi Suzumiya/Ah My Goddess

One day Kyon decides to ask Haruhi why she so strongly believes in Aliens, Time Travelers, Espers, Etc. She explains that shortly after meeting someone named John Smith, she met a women who claimed to be a Goddess that said she could grant her any wish, and her wish was for all those things to exist. Of course, this makes Kyon realize that Haruhi isn't actually THE God, though he decides to keep it a secret from the other 3, since if they know that Haruhi is just a normal person, they might leave.

Sailor Moon/Digimon

In most realities, Luna gives Usagi a Brooch that turns her into the magical Sailor Moon. In this universe, Usagi, as well as Naru, had a small Digital Adventure about a year prior during Christmas, (that giant dragon with the laser on it's back was so cool). Naru's partner, insert appropriate partner here, realizes quick that Naru's mom has been replaced, and the 2 girls and 2 Digimon make arrangements to fight her, Usagi completely avoiding Luna until the Youma is dealt with.

Madoka Magica/Pretty Cure

Madoka makes her wish, "a world where Magical Girls win and despair loses." The world shifts and the 5 girls find themselves in the world of Pretty Cure, somehow with their memories intact, and their magic changed. ...Also Kyubey's a fairy now...OK then.

Angel/Kamen Rider Kiva

Angel Investigations gets a new customer who asks him to help hunt a group of beings called Fangires and in return he and his servants will become employees.

Madoka Magica/Kamen Rider Wizard

After Mami's death, Madoka falls into despair and her body starts cracking, much to Homura's surprise, who hasn't seen this before. Thankfully, words of encouragement from her friends let her return, and giving her the potential to be a new kind of magical girl.

Danny Phantom/Kamen Rider Ghost

Takeru takes a ghost hunting job that takes him too America, crossing paths with Danny Fenton/Phantom. Hopefully there aren't any misunderstandings.

Roswell/Ben 10

While on the run after season 3, the Roswell gang get cornered by the "FBI," but are saved by a boy with an alien watch who introduces the group to the plumbers. The FBI that's been chasing them is revealed to just be a group of xenophobes who are going against their governments orders.

Monster Hunter/Pokemon

With how powerful Legendary Pokemon are, you'd think it would require multiple trainers to beat them. This would be just a simple silly shenanigans fic, re-imagining Legendary Pokemon battles as monster hunter style co-op fights.

Kenichi: The Mightiest Disciple/Ranma 1/2

After getting permanently locked in girl form, which he actually doesn't mind, Ranma leaves Nerima. Years later, Ranko, having mastered Anything Goes Martial Arts, becomes a member of the Ryozanpaku, becoming another Master for Kenichi, as well as developing a crush on the only other Female Master in the dojo.

Digimon/RWBY

Takes place after the X-Evolution movie. Yggdrasil unfortunately succeeds in his plan of restarting the Digital World, leading to the deletion of everything, including his own knights. In a last ditch effort to save everyone, Alphamon activates an unknown program in his code which sends the Royal Knights into Remnant, while also somehow rewrites them into Humans.

Avengers: Earth's Mightiest Heroes/Avengers (MCU)

The Avengers of the animated EMH universe receive a bunch of DVDs with a note telling them that the movies show the events of an alternate reality.
