Well, obviously Turles and Goku are the main characters. Turles is often depicted as the villain in the original story, but in fanfiction, he can be portrayed in different lights. Goku, on the other hand, is the hero. Their interactions and the development of their relationship form the core of the fanfiction.
Maybe a fanfic where Goku discovers Turles has a different side to him. Turles could be in a situation where he has to protect something or someone innocent, which makes Goku see him in a new light. They then have to work together to keep this innocent thing safe from other villains in the Dragon Ball universe.
One idea could be a story where Goku and Turles are forced to team up against a new, even greater threat to the universe. They start off distrusting each other due to their past but gradually learn to work together and respect one another's strength.
By having them share common goals. For example, if there's a powerful artifact that both want to keep out of the wrong hands. This would force them to interact and start to understand each other's motives.
First, think about the basic plot. Decide if it's going to be an adventure, a character - study, or something else. For example, if it's an adventure, figure out what kind of adventure they'll go on.
One possible plot could be Goku and Turles forced to team up against a new, powerful enemy. Maybe a villain from another dimension that threatens both their home planets. This would force them to put aside their differences and combine their unique fighting styles.
Perhaps in a different universe, Turles and Goku are brothers. They grow up together, training side by side, but then a prophecy divides them as they are told one must defeat the other for the greater good. This creates a complex relationship full of love, rivalry, and moral dilemmas.
Their relationship could develop through mutual respect for each other's strength. Goku, being the pure - hearted Saiyan he is, might start to see that Turles has potential for good deep down. Turles, on the other hand, could be in awe of Goku's power and gradually change his view of Goku from an enemy to a rival and perhaps even a friend.
In a 'Goku vs Beerus' fanfiction, it's really hard to say who would win. It could depend on how the author wants to write it. If the author wants to show Goku's growth, Goku might win through some new transformation or power - up. But Beerus is a powerful God of Destruction, so he also has a great chance of winning.
It's really hard to say. Goku has his amazing fighting abilities and power-ups. But the Avengers have a lot of different powers and strategies. If the fight takes place in the Marvel Universe, the Avengers might have some home - field advantage. However, Goku's adaptability and his ability to quickly learn in battle could give him the upper hand. Maybe it would end in a draw if both sides respect each other's power and stop the fight before it goes too far.
