You could write a fanfic about the origin of a new villain in Wakanda. This villain could be a result of the scientific experiments that went wrong in Wakanda. The story could show how this villain rises to power and how Shuri and her allies have to stop this new threat to their beloved kingdom.
One idea could be a story where Nakia discovers a hidden threat to Wakanda while on a solo mission abroad and she has to secretly communicate with Black Panther (T'Challa) to stop it. They face challenges in coordinating without alerting the enemy and their relationship deepens through the shared danger.
A great idea for Black Panther Origin fanfiction is to delve into the backstory of the Black Panther suit. Perhaps it was created through a series of trials and errors, and there were other prototypes that had different powers or abilities. You could also write about T'Challa's mother and her influence on his upbringing. She might have had her own set of skills or knowledge that she passed on to him. Additionally, exploring the origin of the Dora Milaje could be interesting. Maybe they were formed as a response to a specific threat to Wakanda long ago.
One idea could be exploring T'Challa's early training with his father. Maybe showing how he struggled at first to master the skills of combat and stealth that are so important for a Black Panther. Another could be delving into the origin of the heart - shaped herb and its connection to the Panther God in a more detailed way, like how it was discovered and first used.
One idea could be an OC who is a scientist from a small, isolated Wakandan village. This OC discovers a new type of vibranium - like mineral that has unique properties. They then have to convince the royal family and the Wakandan scientific community to take it seriously, facing many challenges along the way.
A plot idea could involve T'Challa's journey to discover a long - lost Wakandan artifact. Along the way, he has to face off against a group of thieves who also want the artifact for their own nefarious purposes. This could test his skills as the Black Panther and his leadership abilities within Wakanda.
One plot idea could be Ramonda dealing with the aftermath of T'Challa's passing in a more in - depth way. She could have secret meetings with Wakandan elders to plan for the future of Wakanda without revealing her true intentions to the public. Another idea is Ramonda traveling to other hidden tribes within Wakanda that were not fully explored in the movie, and there she discovers a new power source or ancient technology that could change Wakanda's fate.
Maybe a story where Draco is a part of a group that is trying to steal Wakandan technology, but during the process, he has a change of heart. This could involve a lot of action and character development as he battles his own motives and the loyalties he has with his original group.
A plot idea could be that the Sharingan, a powerful ability in Naruto, is somehow connected to the vibranium in Wakanda. A character from Naruto discovers a small piece of vibranium and it unlocks a new form of the Sharingan. This leads to both Naruto and Black Panther characters trying to understand this connection and protect the vibranium from falling into the wrong hands.
Captain America would be an interesting character to pair with Black Panther. Their leadership styles are different yet complementary. Cap's more straightforward, old - fashioned leadership combined with Black Panther's more technologically - advanced and culturally - rich leadership could create some great interactions and story moments.
Perhaps there's a plot where a powerful artifact is stolen and both Wonder Woman and Black Panther suspect each other at first. But then they realize they've been set up and join forces to find the real thief. The story could explore their different cultures as they work together, like how Wonder Woman's Amazonian values and Black Panther's Wakandan values might clash or complement each other.
