Adventure is also a common theme. The characters from both Naruto and Equestria are often put into new situations and have to go on quests. They might be exploring new lands that combine elements of both universes, or they could be on a mission to save one of the two worlds from a threat that somehow links the two. For instance, a dark force that is affecting both the ninja world and Equestria.
Twilight Sparkle from My Little Pony is also quite popular in these crossovers. Her intelligence and powerful magic make her a great counterpart to Naruto. She can have really interesting interactions with Naruto, whether it's about sharing knowledge or working together in battles.
Another idea for a fanfiction could be a crossover of the training systems. Naruto could introduce his intense ninja training to the ponies in Equestria. The ponies, in turn, show Naruto how their magic works in more detail. This could lead to some really fun and unique character development as they learn from each other.
One interesting concept could be a crossover of abilities. For example, Naruto's ninjutsu skills combined with the magic from Equestria Girls. Maybe Naruto could learn to use some pony magic in the fanfiction world, or the Equestria Girls characters could gain some ninja-like speed and stealth.
There's also 'Equestria's Ninja'. This fanfic has elements where the ponies in Equestria start to learn about Naruto's ninja ways. They incorporate some of the ninja techniques into their own magic - based skills. It shows how two very different worlds can blend and influence each other in a creative way.
Another often - seen pairing is Sakura and Twilight Sparkle. Sakura is a strong - willed and intelligent character in Naruto, and Twilight is the same in Equestria Girls. They could bond over their love for knowledge, with Sakura sharing her medical ninjutsu knowledge and Twilight sharing her magical research. Also, they could support each other in facing challenges that require both physical and magical skills.
I'm not entirely sure what specific 'Sharing Tongues' Equestria Girls fanfiction you're referring to. It could potentially be about the characters sharing secrets or some form of communication in the Equestria Girls universe. Without more context, it's hard to analyze in detail.
One possibility could be a character who has a deep understanding of magic and uses it to help the ponies in Equestria. This person might have studied magic from a different realm and brings unique spells and techniques to solve problems in Equestria.
Gohan's powers would probably be seen as extremely strange and almost magical to the ponies. His ability to fly without wings, shoot energy blasts, and his super - strength would be beyond their comprehension. They might initially be frightened of him, thinking he's some kind of dangerous being. But once they see he's there to help, they would be in awe of his powers and see him as a powerful ally.
