Well, it's not impossible. In the Black Panther story, M'Baku and Shuri have a lot of interactions. M'Baku has his own code and values, and Shuri is constantly innovating. Their paths cross often. If the story were to take a romantic turn, it could be really exciting. Maybe a situation where they are forced to rely on each other in a difficult time could spark the beginning of a love story.
It could start with mutual respect. M'Baku respects Shuri's intelligence and Shuri respects M'Baku's strength. Then, they might be paired up on a mission to save Wakanda. During this mission, they see each other in a new light. M'Baku might be impressed by Shuri's quick thinking and Shuri by M'Baku's fearless leadership. This could be the start of their love story.
In the comics, M'Baku is not typically considered a villain. He may have his own conflicts and challenges, but he doesn't fit the traditional villain mold. He has moments of cooperation and conflict with other characters depending on the storyline.
The plot could start with some sort of interdimensional rift that brings Gregor Clegane to Wakanda. Black Panther, seeing this strange and brutish intruder, decides to confront him. At first, Gregor might seem to have the upper hand due to his size and brute strength. But as the battle progresses, Black Panther figures out his opponent's fighting style and starts using his technology, like the energy daggers and his suit's abilities, to gain the advantage. Eventually, Black Panther manages to defeat Gregor and figures out a way to send him back to his own world.
Black Panther would likely win. Black Panther has the advanced technology of Wakanda at his disposal, along with his enhanced physical abilities from the heart - shaped herb. He is highly agile, has superhuman strength, and his suit can absorb and redistribute kinetic energy. Gregor Clegane is a formidable brute in the Game of Thrones universe, but his strength is mainly based on his size and combat experience with medieval weapons. Against Black Panther's high - tech arsenal and superhuman skills, he would be at a disadvantage.
The Black Panther comic has its own unique fictional universe and narrative that is not related to the Black Panther Group. The comic's creation was based on comic book concepts and storytelling rather than any direct connection to the group.
At first, there would be a lot of tension. The Wakandan people might be shocked by M'Baku's actions. However, if they both put Wakanda's interests first, they could gradually rebuild their relationship. M'Baku might offer some form of apology or restitution, and T'Challa could show his forgiveness and leadership by accepting it and moving forward together for the betterment of Wakanda.
There might be a m'baku fanfic that focuses on his relationship with other Wakandan characters. For example, his interactions with Shuri. It could explore how their different views on technology and tradition collide and then gradually lead to an understanding and mutual respect, creating a unique bond between the two.
