Another plot could be that they are on a mission together to save the world from a new threat. Along the way, they have deep conversations about their families, friends, and what it means to be a hero. Videl might start to see Goku in a different light, not just as a powerful fighter but also as a great friend and mentor.
Maybe in the fanfiction, Goku helps Videl discover a new power within herself. He trains her in his special way, and she becomes much stronger as a result. It could also involve some comical moments where Goku's naivete about normal life clashes with Videl's more down - to - earth personality.
In some versions, the female Goku could be part of a prophecy. The two Gokus meet, and at first, there is some confusion and misunderstanding. But as they get to know each other, they discover that they are key to fulfilling the prophecy. They combine their powers and defeat an ancient evil that was threatening both of their worlds.
Maybe Gine meets Goku during a time when he is facing a great internal struggle. She offers him the motherly love and guidance he never had growing up. This could lead to Goku having a new sense of purpose and inner peace, which in turn affects his relationships with his friends and family on Earth.
One interesting idea could be the clash of their different power systems. Goku has his ki-based attacks and Super Saiyan forms, while Sonic has his speed and Chaos Emerald powers. Maybe they could have a friendly sparring match to test each other's abilities.
One idea could be that Goku accidentally travels to the RWBY universe during a sparring session that goes wrong with Whis. He could be mistaken for a powerful Grimm at first, causing chaos. Then, he teams up with Team RWBY to fight a new super - strong Grimm that threatens all of Remnant.
Another idea for a fanfiction is that Goku and Videl get transported to a parallel universe. In this universe, their roles are a bit different. They have to adapt to the new situation while still maintaining their core values, and it could lead to some really exciting storylines as they explore this strange new world together.
There are fanfictions where Goku and Videl team up to fight a new and powerful enemy. This enemy could be from another dimension or a long - lost evil that resurfaces. The story could show how their different fighting styles complement each other. Also, some fanfictions might explore what would happen if Videl had to save Goku for a change, reversing their usual roles.
Well, perhaps in the fanfiction, a monster has the ability to steal the energy of the Z - fighters. Gohan gets targeted first, and Videl, being his wife, tries to find a way to stop the monster. She teams up with some of Gohan's old friends like Piccolo. Another plot could be a monster that can change its form into anyone. It disguises as Gohan to create chaos, and Videl has to use her detective skills to figure out the real Gohan and stop the monster. Also, there could be a monster from another dimension that wants to take over Earth. Gohan and Videl are the last line of defense.
One idea could be that Goku and Goku Black are forced to team up against an even greater threat from another universe. They start to understand each other's fighting styles during the battle and gradually develop a grudging respect for one another.
In this fanfiction, Goku's trait of being a family - oriented person could also play a role. He might share stories about his family with Videl, and she could be inspired by the close - knit relationship he has with his loved ones. Videl's determination could also lead her to push Goku to train harder or think differently in certain situations.
In some 'Goku meets Goku fanfiction', they could team up against a super powerful enemy that neither could defeat alone. They would combine their signature moves like the Kamehameha for an ultimate attack.
