In some fanfictions, Izuku's black lightning quirk could have unique side effects. Maybe it drains his energy in a different way than normal quirks, leading to him having to find creative ways to manage his power usage during battles. This could add a whole new layer of complexity to his character development.
The 'Mentor Figure' trope is also quite common. Given the power of the lightning quirk, Izuku usually needs someone to guide him. This could be an older hero or even a mysterious stranger. The mentor helps him understand his quirk better, trains him in combat techniques that are specific to his lightning - based powers, and also gives him moral support. This trope adds depth to the story as it shows Izuku's growth not just in terms of power but also in character.
One great Izuku with Lightning Quirk fanfiction is 'Lightning's Ascent'. In this story, Izuku discovers his unique quirk early on and has to learn how to control it. It's really exciting as it shows his journey from being an outcast to a hero in training with a powerful and rare quirk.
Well, his original quirk is One For All which is more of a power - storing and transferring quirk. The black lightning quirk in fanfiction is likely more offensive - oriented. It can be used for direct attacks like shooting bolts of black lightning at enemies.
One interesting story could be where Izuku's portal quirk allows him to access different dimensions filled with unique heroes and villains. He might use this to learn new combat techniques.
In some Izuku Pride Quirk fanfictions, his quirk could be linked to the pride of others. So, when he's around people who are proud of themselves or their achievements, his quirk gets stronger. This creates an interesting dynamic where he has to surround himself with positive and confident people to reach his full potential. It also gives room for character development as he learns to inspire pride in others to strengthen himself.
One interesting Izuku chain quirk fanfiction could be about Izuku having a chain quirk that allows him to connect with people's emotions. He uses this quirk to bring together a divided class of heroes - in - training. The chains represent the bonds he forms with his classmates, and he uses these connections to overcome various challenges in the hero academy.
There might be a fanfiction where Izuku's snake quirk has a secondary power of camouflage, like a snake in the grass. He uses this to surprise his opponents during battles. He can blend into his surroundings and strike when the time is right.
A third plotline could be Izuku being targeted by villains who are interested in his black lightning quirk. They might see it as a powerful tool or a key to some greater scheme. This would put Izuku in a dangerous situation and force him to rely on his friends and his own growing skills to protect himself and the ones he loves. His friends might also have to step up and help him develop new strategies to combat these villains who are specifically after his quirk.
You can try searching on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just type in 'Izuku has black lightning quirk' in the search bar, and it should show you relevant stories.
There are also fanfictions where Izuku's quirk has a hidden aspect. Maybe his connection to One For All unlocks memories or abilities from the previous users in a more profound way. For instance, he might be able to access the combat knowledge of the past users directly, almost like having an in - built combat instructor guiding his every move.
