A plot could involve Lightning and Snow accidentally swapping powers in the FFXIII world. Snow would struggle with Lightning's quick and precise attacks, while Lightning would have to adapt to Snow's more brute - force style. This would lead to some humorous moments as well as a deeper understanding of each other's abilities and how they complement each other.
One great fanfiction idea could be that Lightning and Snow have to team up for a dangerous mission in the world of FFXIII. They start off with their usual differences and tensions but as the mission progresses, they come to understand and respect each other more deeply. Lightning realizes Snow's determination isn't just bravado but a real will to protect, and Snow sees that Lightning's cold exterior hides a very passionate heart.
A plot could involve Black Lightning training a new generation of metahumans. He could open a school or a training facility where he imparts his knowledge and values. This would also bring in new characters and relationships. Or, what if Black Lightning lost his powers temporarily? How would he deal with it? He could rely on his martial arts skills and detective work to still protect the city.
The theme of family - like bonds is quite common too. Since both Lightning and Hope have lost family members in the game, they might form a family - like relationship in fanfictions. They support each other, protect each other, and fill the void left by their lost families. And of course, there are also fanfictions that explore a romantic relationship between them, though this is not as common as the other themes.
One interesting plot could be that Black Lightning's daughter (from the show or comics) starts to develop powers that are far more powerful and unstable than his own. He has to seek help from other DC experts in power control to help her, all while facing off against villains who see her as a weapon. Another idea is a story where Black Lightning is framed for a crime he didn't commit in the DC universe. He has to go on the run, using his wits and powers to clear his name, and in the process uncovers a conspiracy that reaches the highest levels of power in the DC world.
One plot idea could be that Lightning and Cloud are from different worlds that are on the verge of colliding. They have to team up to find a way to stop the cataclysm. Along the way, they discover they have more in common than they thought and develop a deep bond.
One idea could be that a character gains a special musical power after being struck by lightning during a glee club rehearsal. They can then use this power to create amazing performances and inspire the whole club.
