In order for a male OC to be well - integrated into the BNHA world in a reincarnation fanfiction, his goals and motivations need to align with the world's values. If the BNHA world is all about heroism and saving people, the male OC's past - life experiences should lead him to have similar values. For example, if he died heroically in his past life trying to save others, he would be more likely to strive for heroism in the BNHA world. His appearance can also play a role. If he has a unique look that stands out but still fits within the BNHA aesthetic, it can make him more memorable. Additionally, his speech patterns and cultural references from his past life can add an interesting layer to his character, as long as they are not too out of place in the BNHA setting.
First, give the male OC a believable backstory related to his past life and how it ties into the BNHA world. For example, if he was a scientist in his past life, his knowledge could be used to develop new support items for heroes. Second, have him interact with the existing characters in a natural way. He could start as a transfer student at UA and make friends or rivals with the canon characters. Third, give him a unique quirk that both fits the BNHA universe and is related to his past - life experiences.
To integrate a male OC well in a 'bnha x male oc reincarnation fanfiction', consider his personality. If he was a shy person in his past life, his reincarnation could be a chance for him to become more outgoing in the BNHA world. He can join clubs or teams at UA, like the hero course training teams. His quirk should also be something that can be incorporated into the BNHA power system. For instance, if his past - life skill was cooking, his quirk could be related to enhancing the taste or nutritional value of food, which could be useful for heroes' training diets. Also, let his relationships develop gradually. He might start off being intimidated by All Might but over time learn from him and form a mentor - mentee relationship.
The OC can have pre - existing relationships with some of the minor characters in the High School DxD world. For example, they could be an old friend of a side character who then gets introduced to the main group. This way, it feels more natural for them to be part of the story.
To integrate an OC well, first, consider their personality. If the OC is a confident and brash character, they could contrast with Android 21's more complex and often reserved nature. Second, think about their goals. If the OC's goal is to find a cure for a certain disease that Android 21 might be related to in some way, it creates an instant connection and a plot thread. Third, make sure their appearance also fits the DBZ aesthetic, like having a unique fighting gi or a distinct hairstyle.
Give the OC a unique skill or trait that is relevant to the Sherlock universe. It could be something like an eidetic memory or a talent for deciphering ancient codes. This way, they can interact with Sherlock and the other characters in a meaningful way, either as an ally or an adversary.
To integrate a male OC well, he should have a connection to the existing elements of the story. For example, if he has a past with the Void magic that is so important in the Familiar of Zero world. Maybe his family was involved in some way with the secrets of the Void. Or he could be related to one of the minor characters that we haven't seen much of in the original story. This would make his presence feel more natural.
Another way is to make the OC wizard an ally of the Huntsmen and Huntresses. They could assist in battles against the Grimm. For instance, the wizard could use their magic to heal the wounded or create illusions to confuse the Grimm. This would make them a valuable asset in the fight against evil in the RWBY world.

The oc should have a backstory that ties in with the supernatural world. If it's a world of demons and angels, the oc's past could involve some sort of encounter with these beings that led them to be in this world now. This makes their presence more believable.
A Zoro OC can be well - integrated by having a connection to the existing world of One Piece. Let's say the OC has a dream related to the All Blue, just like Sanji. This connection to an existing concept in the One Piece universe makes the OC feel more at home. Their relationships with other characters are also crucial. If the OC has a friendly rivalry with Zoro, similar to Zoro's relationship with Sanji, it adds depth to the story. They can compete in sword - related challenges and in the process, both grow as characters.
