Writers often draw inspiration from the OC's backstory. If the OC is from a world full of ice, the Keyblade might have a frosty look with ice - like blades and a hilt that resembles a frozen crystal. They also consider the OC's personality. A more aggressive OC might have a Keyblade with sharp, jagged edges, while a calmer one could have a more elegant and streamlined design.
Some popular OC Keyblade wielders often have unique backstories. For example, there's one OC who was a lost soul from a forgotten world. They had to struggle to find their place among the Keyblade wielders. Their journey usually involves self - discovery and facing the Darkness within. They often have distinct keyblade designs too, which are inspired by their home world or their personal journey.
Well, a really exciting plot might involve characters from different worlds within the Kingdom Hearts universe who were previously thought to be lost or dead suddenly reappearing during the Keyblade War. They could bring with them new powers or knowledge that shakes up the whole conflict. For example, if a character from a long - forgotten world shows up with the ability to nullify certain Keyblade attacks, it would completely change the dynamics of the battles. There could be a race among the warring factions to either recruit this character or eliminate them. And as the story unfolds, we could see how the different Keyblade wielders' loyalties are tested in the face of this new threat or opportunity.
A character who has the power to see the future of the Keyblade War could be really interesting. They would know the outcome of certain battles and events, but be unable to change them directly. This would put them in a moral dilemma, especially if they see friends or allies about to be defeated. They could try to influence the war in indirect ways, like giving advice that seems cryptic but is actually meant to guide the other Keyblade wielders. Their presence would also make other characters question whether fate can be changed or if everything is already predetermined in the context of the Keyblade War.
In these fanfictions, the author has a lot of creative freedom. They can shape the OC to be whatever they want. The OC could be from a completely different background than the characters in the original Kingdom Hearts. This can lead to interesting plotlines. For instance, if the OC is from a world based on ancient mythology, it can introduce new enemies and challenges for Sora and the OC to face together.
There are quite a few. One popular one is 'Axel's Redemption' which delves deep into an original character's journey alongside Axel. It really explores the complex relationships within the Kingdom Hearts universe in a new and exciting way.
One interesting concept could be the unique character designs of the self - inserted original characters (OCs). They often bring fresh perspectives and abilities into the 'Kingdom Hearts' universe. For example, an OC might have a special power related to the Keyblades that we haven't seen in the original game series. Another concept could be the new storylines that are created around these OCs. They can interact with the existing characters in unexpected ways, like befriending Sora or Riku and going on adventures with them that deviate from the main game plot.
First, develop a unique backstory for your male OC. Consider his origin, like if he's from a different world in the Kingdom Hearts universe. Then, give him distinct abilities that tie into the game's mechanics, for example, a special keyblade power. Next, create relationships with existing characters. Maybe he has a rivalry with a Heartless or forms an unexpected friendship with a Disney character. This will add depth and interest to your fanfiction.
One thing that makes it special is the ability to see Sora in new situations. With an OC, the story doesn't have to follow the exact same path as the original game. It can deviate and show Sora reacting to things that the game didn't cover.
A sense of humor can be a great trait for a Kingdom Hearts male OC. It can lighten the mood during tense situations, like when facing a horde of Heartless. Also, intelligence is valuable. An intelligent OC can figure out the mysteries of the different worlds and the secrets of the Heartless and Nobodies. And of course, courage. It takes a lot of courage to fight against the forces of Darkness in this universe.
