Black Star might leave due to a prophecy he discovers that says he will bring doom to Death City if he stays. So, he leaves to protect his friends. Along the way, he meets other outcasts who help him understand that he can change his fate. He then returns, stronger and more determined to defy the prophecy.
Perhaps Black Star leaves because he feels overshadowed by other characters in Death City. In the fanfiction, he could journey to a different realm where his skills are recognized and he becomes a sort of legend. He then has to decide whether to stay there or return to his friends, realizing that true recognition comes from within.
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.
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.
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.
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.
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 idea could be a crossover where characters from Harry Potter, Star Clan, and Soul Eater end up in a shared magical realm. They could form teams to battle against a new dark force that threatens all their worlds. For example, Harry Potter characters could use their magic, Star Clan members their unique powers, and Soul Eater characters their weapon - meister combos.
One great fanfiction is 'The Bond Beyond Souls'. It beautifully explores the dynamic between Black Star and Kid. The author really delves into their different personalities, with Black Star's brashness and Kid's precision. It has some really cool action scenes that are true to the Soul Eater style.
In Soul Eater Black Star mpreg fanfiction, a frequent theme is the relationship dynamics. For example, how his partner (if there is one in the story) reacts and supports him. Also, there could be themes related to the challenges he faces during the pregnancy, like dealing with his own strength and how it might affect the pregnancy, as well as the social and cultural implications within the Soul Eater universe.
Perhaps in this crossover, the concept of the tailed beasts in Naruto are related to the Kishin in Soul Eater. The tailed beasts are seen as powerful and dangerous entities, much like the Kishin. A group of characters from both universes, including Naruto, Maka, and Soul, come together to find a way to either control or destroy these powerful forces that threaten both their worlds. They would have to learn from each other's strengths and weaknesses to succeed.
It's an action-packed tale with a unique fantasy world. The main character has the power to consume souls and battles various evil forces.
