One idea is to make the OC's lightning power have a unique aspect. For example, instead of just shooting bolts of lightning, they can manipulate the electromagnetic field around them. This would allow for some really cool abilities like levitating metal objects or creating a shield out of a magnetic field. In terms of personality, they could be a bit of a hot - head (pun intended) due to the volatile nature of their quirk. They might rush into situations without thinking, but also have a strong sense of justice that makes them a great hero in the end.
For a My Hero Academia OC with lightning power, you could start by thinking about their appearance. Maybe they have spiky hair that seems to crackle with electricity, like Denki Kaminari but more intense. Their costume could be designed with lightning bolt motifs and made of a material that can withstand their own electrical discharges. For the character's backstory, they could have been struck by lightning as a child and survived, which awakened their quirk. This event could also have led to them being a bit of an outcast, fueling their drive to become a great hero.
One idea could be to make the character with the lightning quirk have a fear of water. This would add an interesting dynamic as lightning and water don't mix well. They could struggle to control their quirk when near water, and it could be a source of internal conflict for them.
A good start is to create a conflict that is related to the OC's lightning power. For example, a villain could be stealing energy from power plants and the OC's lightning power is the key to stopping them. This would immediately draw the reader in as they wonder how the OC will use their power to overcome the villain.
One possible title could be 'Mina and the Mysterious OC: A My Hero Academia Adventure'. This title gives a sense of mystery and adventure, highlighting the relationship between Mina and the original character.
When writing action scenes for a character with a lightning quirk, describe the speed and intensity. For example, 'He shot out bolts of lightning, each one crackling through the air like a whip, their bright light blinding his opponents for a split second.'
One plot idea could be that the Saiyan OC is mistaken for a new type of villain at first. As they try to prove they're not a threat, they start to make friends and learn about heroism. Another idea is that they discover a connection between Saiyan powers and some of the hidden secrets in the MHA world. Maybe there's an ancient power source that only a Saiyan can unlock.
You could create an OC who has a unique quirk like the ability to manipulate shadows but with a drawback that they can't use it in direct sunlight. This would add an interesting dynamic to their story within the My Hero Academia universe.
First, think about their Saiyan powers and how they would translate in the My Hero Academia world. For example, a Saiyan's ability to increase power level could be like a quirk that gets stronger over time. Consider their backstory, like maybe they're a Saiyan from another planet who ends up in the MHA world. Also, their appearance can combine Saiyan features like a tail and spiky hair with the MHA style of clothing.
First, think about their quirk. It should be unique yet fit within the MHA universe. For example, a quirk like 'Shadow Manipulation' could be cool. Then, consider their backstory. Maybe they had a difficult childhood that led to their determination. Also, give them a distinct personality, like being a bit of a loner but with a big heart.
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.
In My Hero Academia fanfiction, power is often portrayed in diverse ways. Some writers may focus on creating new and unique Quirks that the original series hasn't explored. For example, a fanfic might introduce a Quirk that allows the user to manipulate time on a small scale, like slowing down time for a few seconds. This adds an interesting twist to the battles and character interactions. Also, power can be depicted in terms of its psychological impact on the characters. A character with a powerful Quirk might struggle with the responsibility that comes with it, fearing they could accidentally harm others.
