Maybe an old enemy of the Black Panther's family who sees the daughter as a new target. This enemy could be from a neighboring tribe that has had a long - standing feud with Wakanda. They view the daughter, with her mixed heritage, as a symbol of Wakanda's growing power and influence, and they want to stop that by any means necessary. They start causing trouble in Wakanda and try to frame the daughter for it.
It could be a rogue Wakandan scientist who is jealous of the daughter's unique abilities. He might see her as a threat to his own plans of taking over Wakanda's technology and using it for his own evil purposes. So, he tries to undermine her at every turn and stop her from fulfilling her destiny in Wakanda.
The main antagonist could be a powerful sorcerer from a far - off land. This sorcerer has heard of the daughter's powers, which are a combination of Wakandan magic and Storm's weather - controlling abilities. He wants to steal her powers to increase his own. So, he uses his dark magic to create various obstacles and illusions for the daughter to overcome, all while trying to get close enough to her to take her powers.
One possible plot could be that the daughter has to prove herself worthy in Wakanda. She might face challenges from those who doubt her because of her unique heritage. For example, she could have powers from both her mother Storm and her Wakandan lineage. She then goes on a journey to master these powers and earn the respect of the Wakandan people.
An old rival of T'Challa's from his training days could be the main antagonist. This person was always jealous of T'Challa's status as heir to the throne and the future Black Panther. Now, he has found a way to enhance his own abilities and wants to prove that he is the better warrior by taking down T'Challa and claiming the Black Panther mantle for himself. He would know T'Challa's fighting style well, making him a very challenging opponent.
A group of Wakandan nobles who oppose Shuri's rule as Black Panther could be the main antagonists. They believe that the Black Panther should be a more traditional figure and that Shuri's focus on innovation and change is a threat to their long - held power and status. They might plot to undermine her at every turn, from spreading false rumors within Wakanda to allying with external forces against her.
It could be another summoner who is jealous of the panther summoner's power. This antagonist summons a powerful and dangerous beast, like a giant snake, to constantly challenge the panther summoner and try to steal their power or reputation.
It could be someone who wants to steal the knowledge Naruto gained from the Black Panther. Maybe a rogue ninja or a power - hungry villain from another land.
Maybe an organization that wants to use her unique abilities. If she has inherited some special power from Kakashi or has her own distinct skills, an evil organization could try to capture her and force her to work for them. They would be the main obstacle she has to face in the story.
It could be a villain who is after Beast Boy's powers. Since Beast Boy is getting trained by Black Panther and becoming stronger, this villain might see him as a threat. Maybe it's someone like Deathstroke who wants to stop Beast Boy from reaching his full potential under Black Panther's tutelage.
A possible story could be that Storm discovers she's pregnant during a time when Wakanda is facing a new threat. Black Panther is both excited and worried about becoming a father. He tries to balance his duties as king and protecting his family. Storm, on the other hand, is determined to use her powers to keep herself and the unborn child safe.
One idea could be that an ancient Wakandan prophecy foretells the birth of a child from a union like theirs during a time of great change. This leads to both excitement and fear in Wakanda. Some see it as a sign of great prosperity, while others worry about the power the child might possess.
The mother's new partner. He doesn't want the forgotten daughter to be part of the family as he fears she will disrupt the new family dynamic he has been trying to build. He might use various means to keep her away from the family.
