One idea could be that Mustard discovers a new way to use his quirk that gives him an edge in the villain world. For instance, he finds a way to combine his gas - based quirk with some form of mind - control element. This could lead to a story where the heroes have to figure out how to counter this new threat.
A story where Mustard teams up with a hero - in - training who has a quirk that can neutralize his gas attacks. They start off as enemies but gradually realize they can help each other achieve their goals. The hero - in - training wants to prove themselves by reforming a villain, and Mustard wants to get out of the villain life but doesn't know how. So they form an unlikely alliance.
Mustard is an interesting character in My Hero Academia fanfiction. He has unique abilities that can add a lot of depth to a story. His quirk, which is likely related to some form of gas or chemical manipulation, can be used in various ways in fan - created scenarios. For example, a writer could explore how he uses his quirk in a battle against other heroes or villains. It also gives room for exploring his personality, whether he's a villain with malicious intent or a more complex character with a troubled past.
Another plot could involve Ochako being manipulated by a charismatic villain. This villain convinces her that the hero society is corrupt and that by joining the 'dark side' she can actually make a more positive change. She then uses her gravity quirk to disrupt hero operations, like making heroes' equipment float away during battles.
One cool quirk idea could be 'Shadow Mimicry'. The user can blend into any shadow and move freely within the shadow realm, also being able to mimic the actions of those whose shadows they are in. It gives a lot of stealth and surprise attack possibilities in a fanfiction.
Yes, it is quite popular. 'My Hero Academia' has a large and passionate fan base. Fanfiction allows fans to explore different storylines, character relationships, and scenarios that may not be in the original work. It gives them the freedom to expand on the existing universe, whether it's developing new quirk abilities for the characters or creating entirely new adventures for the heroes and villains.
Another approach is to do a Halloween party at UA High. Everyone dresses up in different costumes. Deku could go as All Might in his younger days. There could be a costume contest, and some characters might use their quirks to enhance their costumes. But then, a real threat shows up disguised as a party guest, and the students have to use their wits and powers to stop the danger while still in their party get - ups.
One idea could be that Godzilla arrives in the My Hero Academia world during a major villain attack. The heroes initially see Godzilla as a threat but soon realize that he is targeting the same villains who are causing environmental destruction. His massive size and power could be a game - changer in the battle.
One creative plot is where the Infinity Stones end up in the My Hero Academia universe. The heroes from both worlds have to figure out how to keep them safe from villains. It creates a really unique dynamic as the Avengers' technology and powers mix with the quirks of the My Hero Academia characters.
Maybe the new home is a large treehouse - like structure built in a forest. It would blend in with the natural surroundings and provide a peaceful yet secure place for the heroes. They could have different levels for different functions, like a training area on the lower levels and sleeping quarters on the upper levels. It could also be a place where they can study and analyze the quirks of villains and come up with counter - strategies.
Another concept is that Todoroki was turned into a vampire by a villain's quirk gone wrong. He then has to find a way to reverse it. He teams up with Midoriya, who is determined to help his friend. They search for a mysterious old hero who might know a cure, all while Todoroki battles his inner vampire nature.
One idea could be that Kakashi is somehow transported to the My Hero Academia world. He could become a teacher at UA, using his ninja skills and wisdom to train the students in new and unique ways. His Sharingan would be a very interesting power in the MHA universe.
