Perhaps the new hero in the mlp fanfiction is an outcast pony. They don't fit in with the normal pony society at first. But then, a great danger looms over Equestria. A powerful force is sucking the magic out of the land. This new hero realizes that they have a hidden power within them that can combat this threat. They must then overcome their own insecurities and the doubts of others to save Equestria.
One possible plot for 'a new hero mlp fanfiction' is that the hero is a young pony who dreams of being a great hero like Twilight Sparkle. One day, a magical portal opens up and strange creatures start coming through. The new hero steps up and tries to close the portal. Along the way, they learn valuable lessons about friendship, courage and magic. They also meet some of the classic My Little Pony characters who guide them on their journey to become a true hero.
In 'a new hero mlp fanfiction', the new hero might be of a different pony type. It could be a Pegasus, an Earth pony or a Unicorn. If it's a Pegasus, they might use their flying skills in unique ways to help others. As an Earth pony, their strength and connection to the land could play a key role. And if it's a Unicorn, their magic could be the defining factor in their heroism. The story could also explore how this new hero changes the dynamics in Equestria and inspires other ponies to be better.
As MLP can't really watch fanfiction in a literal way, but if we were to think hypothetically, it could be really interesting. The characters might get new perspectives on themselves or their relationships. For example, if there are fanfictions that explore a different side of a character's personality, it could potentially add more depth to the official portrayal if the creators were to take some inspiration from it. However, this is all just a fun thought experiment as MLP doesn't have the agency to do such a thing.
Perhaps in the fanfic, there could be a villain who is trying to steal the cutie marks of the ponies in the MLP world and use their power for evil in the My Hero Academia world. The heroes from both universes would then have to team up. Deku could use his One For All to protect the ponies, while the ponies could use their friendship magic to support the heroes in combat.
Well, the plot could start with Sweetie Belle being taken by some unknown force. Her friends in Ponyville, like Scootaloo and Apple Bloom, would then notice her disappearance and start to search for her. They might follow clues, ask around, and eventually discover that she was kidnapped by a group who has some sort of vendetta against Ponyville or Sweetie Belle's family. Then they would have to come up with a plan to rescue her, perhaps with the help of Twilight Sparkle and her magic.
A young girl could be the hero. She might find a way to save Christmas when Santa's magic is in danger of disappearing. She uses her courage and kindness to find the missing magic ingredient and restores the joy of Christmas.
One possible power could be telepathy. A new hero with telepathic powers could read the minds of enemies, anticipate their moves, and also communicate silently with the other Avengers during missions. This would give the team a huge advantage in battles.
One unique feature is the combination of powers. In 'My Hero Academia MLP fanfiction', the quirks from My Hero Academia are mixed with the magic in MLP. For example, a character with a fire - based quirk might interact with a unicorn's fire - making spell in a new and different way.
Perhaps it's a new generation of a well - known Harry Potter family. For example, a son or daughter of Harry and Ginny Potter. They could inherit the heroic traits of their parents and become a hero in their own right, only to meet a tragic end in the fanfiction.
One interesting plot twist could be that the son of All Might actually has a quirk that seems weak at first but turns out to be extremely powerful in a unique situation. For example, his quirk might be the ability to sense danger, which initially makes him seem like a liability. But later, when facing an enemy who can hide their presence, his quirk becomes crucial for the heroes' victory.
There could be a new mystery to solve. Maybe something related to a character's past that has been hidden until now.
