In this fanfiction plot, Trunks is on a mission to find a powerful energy source and ends up in Naruto's world. He meets Naruto who is on a mission to retrieve a stolen ninja scroll. They decide to help each other. As they work together, they discover that an evil organization from another dimension is planning to invade both their worlds. Trunks and Naruto then gather their allies from both universes. Trunks brings in Vegeta and Goku, while Naruto gets Sasuke and the other ninja. Together, they form a powerful alliance to fight against this inter - dimensional threat.
The fanfiction could begin with Naruto being curious about a strange energy signature and going to investigate. He finds Trunks, who has just arrived in his world. Trunks is looking for a way back to his own universe. Naruto offers to help. As they search for a solution, they encounter a group of rogue ninjas who are after Trunks' power. Naruto and Trunks fight side by side, with Naruto using his ninjutsu and Trunks using his ki blasts. During the battle, they start to understand each other's powers better and form a strong friendship.
In a scenario where Trunks meets Naruto, their meeting would likely be a clash of two very different cultures. Trunks is used to a world where fighting is often about protecting the Earth from powerful alien threats. Naruto is focused on protecting his village and the ninja world. However, they both have a strong sense of justice. So, they might team up to take on a common enemy that threatens both their worlds, using their unique powers and skills to defeat the foe.
One possible plot could be that Goten and Future Trunks meet during a time - traveling accident. They initially have some misunderstandings due to their different upbringings and experiences. But as they start to train together, they learn from each other's fighting styles and develop a deep friendship. They then team up to face a new, powerful enemy that threatens both their timelines.
In a 'Vegeta meets Trunks' fanfiction, a great plot could be centered around Vegeta finally opening up to Trunks about his own insecurities. Vegeta has always been this tough exterior, but he might share with Trunks his fears about not being able to protect their family or the Saiyan race. This would be a very emotional moment for both of them. Trunks would see a different side of his father, and Vegeta would be taking a big step in their relationship.
In this fanfiction, it could be that King Vegeta mistakes Trunks for a threat at first. But Trunks explains his purpose, which is to protect the Saiyan race. King Vegeta then decides to train Trunks in the traditional Saiyan ways. This training helps Trunks become even stronger and also bridges the gap between their two different generations of Saiyans.
The relationship could develop in a more emotional way. Maybe Trunks gets injured badly in a fight, and Vegeta realizes how much he cares for his son. He then becomes more protective and affectionate towards Trunks. On the other hand, Trunks could also start to understand his father better, seeing that Vegeta's tough love is actually a way of showing his love and concern. This new understanding could lead to a more harmonious and loving relationship between them.
The relationship between Naruto and Bulma would be really fascinating. Since they are from two very different worlds, seeing how they interact, fall in love, and build a family would be a major plot point. Also, how Naruto would train Trunks in his own ninja - like way while Trunks also has his Saiyan powers would add a lot of depth to the story.
One potential theme could be family. Vegeta's relationship with his son is explored, showing how a Saiyan warrior like him can adapt to fatherhood. Another theme might be growth, as Baby Trunks learns from Vegeta and Vegeta also grows as a person through this new connection.
Well, it could be that Vegeta, upon meeting Baby Trunks, realizes the importance of family in a new way. He might start to see the future differently, knowing that he has a son to protect and guide. There could also be some cute moments where Baby Trunks tries to imitate Vegeta's tough guy expressions, which would be quite endearing.
It could be a rogue Saiyan from an alternate timeline who has come to their universe to prove his supremacy. He is jealous of the power that Goten and Future Trunks possess and wants to take it for himself.
It could be Frieza. Since he has a long - standing enmity with the Saiyans. His presence would create a great threat that King Vegeta and Trunks would have to overcome together. King Vegeta has his own history with Frieza, and Trunks knows how powerful Frieza can be in the future.
