No. In the official 'Dragon Ball' story, Vegeta is Trunks' father. Fanfiction might play with the idea for creative or alternate universe purposes, but it goes against the original lore.
Fanfiction authors often like to experiment with different 'what - if' scenarios. Making Goku Trunks' father could be a way to explore how the story would unfold differently. Maybe they want to see how Goku's influence would shape Trunks' personality in a way that's different from how Vegeta does. It could also be a way to merge different story arcs or character traits that don't usually interact in the original series. For example, combining Goku's pure - hearted nature with Trunks' more serious and future - focused attitude. This can lead to a whole new set of adventures and character developments that are not possible in the official story.
It could be his father, Vegeta. Vegeta is known for his strict training methods and high expectations. If Trunks fails to meet those, Vegeta might punish him to make him stronger.
Another possibility could be Draco Malfoy. Think about it. In some fanfictions, they might rewrite the relationships completely. Draco has his own complex character arc, and perhaps in this 'harry potter is not the father' scenario, he ends up being the father due to some unforeseen circumstances, like a misfired spell that alters the course of events related to parentage.
One pairing that pops up is Goku and Chi - Chi. Their relationship as husband and wife can be explored further in fanfiction, especially in scenarios where Goku's Saiyan nature clashes with his family responsibilities. Additionally, Trunks and Future Mai is a pairing that has some popularity. Their relationship in the future timeline and how they support each other can be the focus of some great stories.
In Dragon Ball fanfiction related to Trunks, Michiko could be a potential love interest. She might be a character created specifically for the fanfiction, perhaps a Saiyan - human hybrid like Trunks. She could be a strong fighter or have some unique abilities that draw Trunks' attention and make their relationship develop in the story.
In a 'broly x trunks fanfiction', the two main characters are Broly and Trunks. Broly, known for his extreme power and often uncontrollable rage in the original series. Trunks, on the other hand, is a key figure in the Dragon Ball universe, being the son of Vegeta and Bulma. Their different personalities and abilities make for an interesting dynamic in the fanfiction.
Obviously, Prince Trunks and Pan are the main characters. Trunks is a powerful Saiyan with a complex history. He has time - traveled in the past to save the world and has great combat skills. Pan, on the other hand, is the granddaughter of Goku. She is feisty, brave, and has a lot of potential as a fighter.
