Who could be the main antagonist in a 'Raditz join the Dragon Team fanfic'?

One possible plot could be Raditz initially trying to take over the Dragon Team due to his Saiyan nature. But as he spends more time with them, he starts to understand their values of friendship and protection. He could then use his Saiyan strength to help the team in battles against stronger foes like the Red Ribbon Army or other villains.

Perhaps the main antagonist could be a new character. This new character could be an ancient evil that has been awakened by the presence of the Saiyans on Earth. They see Bardock and Raditz as a threat to their plans of taking over the universe and thus try to eliminate them.

Perhaps the main antagonist is actually an old enemy who manipulates Naruto's team into abandoning him. This enemy could be using mind - control or false information to drive a wedge between Naruto and his team. They do this to weaken Naruto, knowing that his strength comes from his relationships.

Another possibility is a power - hungry ninja within the village who wants to take advantage of Sakura's situation. They might try to manipulate her or use her as a pawn in their scheme to gain more power. Since she's been abandoned, she may be more desperate and easier to influence, making her a prime target for this type of antagonist.

Danzo could also be the main antagonist. He is known for his underhanded methods and distrust of anyone with too much power. Since Naruto has the power of the Nine - Tails, Danzo might spread lies within Team 7 to make them think Naruto is a danger, causing them to betray him.

There could be a group of bandits who have been causing trouble around the areas where Naruto is training Team 8. They don't like the idea of a strong team emerging in their territory. So, they start attacking the team during their training sessions. These bandits might have some crude but effective combat techniques and they also use the terrain to their advantage, which makes them a formidable antagonist for Team 8 during their training with Naruto.

The World Government could be the main antagonist in a more complex way. They could be secretly manipulating events to pit Dragon and Luffy against each other. For example, they could spread false rumors about Luffy being a tool of the revolutionaries, which would make other pirate crews and kingdoms target him, and at the same time make Dragon look bad for having a son who is causing so much chaos. This would force Dragon and Luffy to either fight each other or find a way to clear their names together.

In the fanfic, if Raditz joins the Dragon Team, it could be a game - changer. He has a lot of power that could be harnessed for good. The team could use his strength to protect the Earth more effectively. However, Raditz would need to learn to work with others. His Saiyan pride might get in the way initially, but over time, he could become a valuable asset. For example, he could train with Goku and the others, and they could all learn from each other.

The Saiyans joining the Dragon Team could lead to a whole new set of adventures. Maybe they start exploring new planets together in search of the Dragon Balls. With the Saiyans' strength and the Dragon Team's knowledge, they could face off against powerful foes that neither could have defeated alone. For instance, they might encounter an evil race that has the ability to nullify ki attacks, but the combined efforts of the Saiyans' physical prowess and the Dragon Team's strategic thinking would help them overcome this threat.

It could be a former member of Akatsuki who has a personal vendetta against Naruto. Maybe they escaped from prison and now they want to take revenge on Naruto for all the things he did to Akatsuki. They would be a very powerful and dangerous antagonist as they possess knowledge of many dark jutsus.
