In fanfiction, if Black Star turns evil, it would be a really interesting development. Black Star has always been on a path of growth and self - discovery in the original series. But if he goes to the dark side, his character arc would take a drastic turn. His pride and ambition could be twisted into something malevolent. He may start to see his friends as obstacles to his new - found evil goals. This could lead to some really intense and dramatic storylines, like battles between him and his former comrades, or him causing destruction in the name of his new evil ideology.
His confidence could turn into overbearing arrogance. Instead of being a source of motivation, it would be a tool to belittle others. His determination might become a stubborn and unyielding obsession with power and domination.
Black Star leaving could trigger a series of events. He could end up in a place full of dark magic where he has to fight to survive. Meanwhile, back in Death City, there could be an attack by an enemy who was waiting for Black Star to be gone. The remaining characters would have to step up and defend the city without him, which could be a great source of character development.
In many Black Star fanfictions, his relationship with the other characters is a key aspect. He might have interesting interactions with Maka and Soul. Maybe there's a fanfic where they team up for a special mission and Black Star has to learn to work with them in a different way than he's used to.
One idea could be that Black Star leaves to pursue a solo mission to prove his strength without relying on his friends. He might encounter a powerful and mysterious foe that challenges his very core beliefs. This would make for an exciting story as he battles not just physically but also internally.
The theme of friendship also shows up a lot. Despite his brash exterior, Black Star has friends. Fanfictions may show how his friendships are tested, for example, when he has to make a difficult choice that could potentially harm a friend, and how he navigates through that moral dilemma.
Well, in a fanfiction where Maka is kidnapped, it could lead to a lot of different scenarios. Her friends, like Soul, would probably go on a desperate search for her. They might face many obstacles and enemies along the way. It could also be a chance for Maka to show her inner strength even while being held captive, perhaps by outwitting her kidnappers in some clever ways.
In a fanfiction where Black Star becomes a weapon, his design as a weapon would probably be very unique. Given his love for being flashy and his ninja - like style, he could be a weapon that has a lot of sharp edges and a sleek, black design. Maybe he'd be a sword with some sort of special ability related to his ninja skills, like being able to disappear and reappear during combat, or having the ability to cut through dimensions.
One common theme is power and growth. Black Star is often depicted as striving to become more powerful, whether it's mastering new techniques or unlocking hidden powers. Another theme is friendship. His relationships with characters like Maka, Soul, and others are explored, showing how they support and sometimes challenge him on his journey.
If Black Star and Tsubaki kiss in the fanfiction, it could change the overall tone of the story. It might introduce more emotional depth. For instance, if there are future battles or challenges, their relationship could be a source of strength. However, it could also create some conflict. Maybe they start to neglect their training or duties because they are so caught up in their new relationship. Or perhaps there are rules in the Soul Eater world about relationships between meisters and weapons, and they have to face the consequences of breaking those rules. It would be a major plot development that could take the story in many different directions.
In a 'Percy Jackson turns evil' fanfiction, he might use his powers against his former friends. For example, his control over water could be used to flood Camp Half - Blood. His knowledge of the demigod world would also be a weapon in his hands to outwit and defeat those who oppose him.
