I think All Might in his prime could be a great main character for this type of fanfiction. If he were to travel to different dimensions, he could spread his symbol of peace in new worlds. He would face different types of villains and heroes, and his experience and power would make for an exciting story. Plus, we could see how he adapts his hero style to different situations in various dimensions.
One idea could be the dimension traveller arriving in a world where quirks are reversed. For example, heroes have villain - like quirks and vice versa. This would create a lot of chaos and interesting character interactions as the traveller tries to figure out how to navigate this strange new world.
To write a good My Hero Academia dimension fanfiction, start with a unique concept. It could be a dimension where the hero - villain dynamic is completely reversed. Develop your characters in new ways. For example, a side character from the original could become a main character in your fanfic. Use vivid descriptions of the new dimension, like its different landscapes and quirk manifestations. Also, make sure the plot has a clear arc, with a beginning, middle, and end that ties everything together.
Well, a common trope is the alternate universe exploration. In My Hero Academia dimension fanfiction, writers often take characters into different versions of the MHA universe. There's also the redemption arc trope for villains. They might find themselves in a different dimension where they get a chance to change their ways. Time - travel is another trope, where characters go back or forward in time within the MHA dimension.
There's no way to know for sure without reading the fanfiction. However, it could potentially be a side character that the author has decided to make the focus. For example, a character who has always been in the background but suddenly their disappearing act becomes the central mystery. It could also be a hero who has been mentioned briefly in the original series but is now given a whole new story arc in this fanfiction where their disappearance is the key plot point.
It could be a new student at U.A. High School. Maybe someone who was a hardcore gamer in their previous life and now has to adapt their gaming skills to the hero world. They would have unique ways of approaching hero training and battles.
Bakugo could also make an interesting main character. His explosive personality combined with a gamer ability would be really cool. He could be super competitive in the 'gamer' aspects of the story, like ranking up in a hero - ranking system that works like a game. And he would be all about proving he's the best, not just in real - life heroics but also in the game - like challenges.
It could be a new student at U.A. High School. A cyborg with a unique quirk related to their mechanical parts, like the ability to fly using jet - propelled limbs. This character could be the main focus as they learn to control their powers and make friends among their classmates.
Bakugo could be an interesting vampire. His hot - tempered nature combined with vampiric powers would make him extremely formidable. He might struggle with the bloodlust, which could add a new layer to his character development.
AO3 is great for My Hero Academia fanfiction. It allows for detailed tagging, so you can easily find the specific type of story you're interested in, whether it's about a particular character, a certain ship, or a specific plot type. FanFiction.net has a large and active community, so there are always new stories being updated. Wattpad, on the other hand, may have some unique interpretations and crossovers that you might not find elsewhere.
All Might could also be an interesting choice. If someone was reincarnated as a younger All Might, they could change some of the events that led to his decline in health. They could also learn from his mistakes and become an even more powerful and long - lasting symbol of peace.
