Yes, there are. You can find such fanfictions on various fanfiction websites. Some writers like to explore new abilities for Naruto, and telepathy is an interesting one. It can add a whole new layer of interaction and plot development in the story.
One possible plotline is that Naruto uses his telepathy to communicate with the spirits of the past Hokages. He could gain wisdom and knowledge from them that would help him in his battles and in leading the village. Another plotline could be that he uses it to understand the motives of the Akatsuki members better and tries to convert some of them to the side of the Leaf Village.
There are indeed some. However, the quality can vary greatly. You might have to sift through a number of them to find ones that really capture the essence of Glynda's character and the use of her telepathy. Some may focus more on action, while others on the emotional aspects of her telepathic interactions.
In Harry Potter fanfiction about telepathy, one common theme is how characters might use it in the wizarding battles. For example, Harry could potentially use telepathy to communicate with his friends without the Death Eaters detecting their plans. It adds a new layer of strategy and secrecy to the magical world.
Often, in these fanfictions, the use of telepathy among the students at Hogwarts can create a whole new dynamic. They could form telepathic study groups, sharing knowledge instantly. This would change the way they learn magic and interact with each other, making Hogwarts an even more interesting place.
Maybe a plot where Glynda's telepathy is somehow affected by an outside force. This could lead to her losing control over it at times and causing chaos, and she has to find a way to regain control and fix the problems it causes. It could also involve her learning more about her own power through this struggle.
The telepathy could open up new ways of experiencing the world for the mantis. It might be able to sense the emotions and thoughts of other nearby creatures, not just mantises. This could lead to a more complex understanding of the ecosystem it lives in. For instance, it could detect when a predator is in a weakened state due to an injury or illness, and avoid areas where there are a large number of aggressive or desperate prey. This new awareness could change the mantis's entire survival strategy.
Some people believe they are real. There have been many accounts where animals seem to know things that are beyond normal perception. For example, pets often sense when their owners are coming home, even when they arrive at unexpected times. However, from a scientific perspective, there is no conclusive evidence yet to prove animal telepathy.
One significance is that it challenges our concept of communication. It makes us think about what it would be like to directly share thoughts. In science fiction like 'Stranger Things', Eleven has some telepathic powers which she uses to fight the monsters from the Upside - Down. It gives a new dimension to how characters interact and solve problems.
