There could be some original characters as well. For example, an old wizard who has been a mentor to the older brother, teaching him some ancient magic that no one else at Hogwarts knows. And perhaps some dark wizards who are after the older brother because they see him as a threat to their plans. They might try to use Harry to get to the older brother. There could also be some magical creatures that have a special bond with the older brother, like a phoenix that only he can communicate with. This phoenix could be a source of power and guidance for him in his journey to protect Harry.
Another potential character could be a relative from the Potter family that was thought to be dead. This relative might have some secrets about the Potter family's magic that the older brother discovers. This discovery could be a turning point in his ability to protect Harry. And there could be some Hogwarts professors who play important roles. For instance, Professor Snape might have a different attitude towards the older brother compared to Harry. He might see the older brother as a more serious threat or an ally, depending on the brother's actions and intentions.
In this fanfiction, the older brother of the Boy - Who - Lived (BWL) might have a very different relationship with the wizarding world.

But when danger really comes to Harry, he steps up. He might have some knowledge about the dark arts that he uses to fight the enemies in a more unorthodox way compared to Dumbledore's side.
There could be. In fanfiction, the sky's the limit. Since this is a 'harry older brother of bwl' fanfic, his powers could be something that sets him apart from the original Harry.

Obviously, Harry Potter himself would be the central character. Hermione could be part of the harem, as she has always been close to Harry. Luna Lovegood might also be there, with her unique and dreamy personality. Additionally, some new original characters could be introduced, like a powerful witch from a Vegas - based wizarding family.
There could also be new characters introduced. Maybe other magizoologists from different parts of the wizarding world. They could have different approaches and beliefs about magical creatures. Some might be rivals, trying to outdo Harry in the discovery and study of new species, while others could be mentors, guiding him in the complex world of magizoology.
Obviously, Hermione Granger would be a great addition. Her intelligence and loyalty would make her an important part of the harem. Ginny Weasley is also a likely candidate.

And Hagrid, who later played an important role in Harry's life, could perhaps be there to bring some news from the wizarding world to the Potters.
He could meet an Egyptian wizard who is an expert in ancient magic. This wizard could teach Harry a great deal about the history of magic in Egypt.
