What are some interesting plot ideas for 'Dragon Ball Z Dimensions Fanfic'?

One idea could be a new villain from an unknown dimension arriving in the Dragon Ball universe. This villain has a unique power that nullifies ki attacks, forcing the Z fighters to rely on their martial arts skills alone.

One idea could be a gamer getting transported into the Dragon Ball Z universe and having to learn the ki techniques like a newbie Saiyan. They could start from the very bottom, training with Goku or Vegeta, and slowly rise in power. Another could be a gamer who has the ability to hack the Dragon Ball Z game world in a way that changes the rules, like making the Dragon Balls more accessible but with a new set of challenges to face when using them.

One idea could be Shaggy getting transported to the Dragon Ball Z universe and accidentally eating a Senzu bean, which gives him superhuman strength and he has to figure out how to control it. Another could be Shaggy befriending Goku and teaching him some of his laid - back ways while Goku teaches Shaggy how to fight.

One idea could be a crossover where the characters from RWBY and Dragon Ball Z have to team up to fight a common enemy. For example, the Grimm from RWBY could be combined with some of the villains from Dragon Ball Z, like Frieza. The RWBY characters could learn some of the ki techniques from Dragon Ball Z, and in return, the Dragon Ball Z characters could learn about the unique Dust powers in RWBY.

Another interesting plot could be that the gamer aspect brings in virtual reality elements. The Z - fighters enter a virtual world where they have to fight enemies with different rules. This virtual world could have power - ups and obstacles that are based on video game concepts, like finding hidden keys to unlock new areas or defeating bosses to gain special abilities that they can then use in the real Dragon Ball Z world.

One idea could be a crossover with the Naruto universe. Goku and Naruto could team up to fight a common enemy. Maybe they face an evil villain who has the power - stealing abilities like Cell and the ability to use powerful ninja jutsus. Another plot could be a crossover with One Piece, where Luffy and Goku have a friendly competition about who can eat more food and then end up having to work together to defeat a new threat at sea that has the strength of Saiyans and the deviousness of pirates.

Perhaps a fanfiction where a young Saiyan from a destroyed planet manages to find their way to the Xenoverse 2 world. This Saiyan has a different fighting style compared to the ones we know. They join the Time Patrol not just to save timelines but also to find a new home for their kind. Along the way, they face discrimination from some of the other races in the Xenoverse due to their Saiyan heritage, but they prove themselves worthy through their strength and determination.

Goku could still be the main character even in a dimension - hopping fanfic. His adaptability and thirst for stronger opponents would make him a great fit to explore different dimensions.

One idea could be a tournament where all the past villains are resurrected to compete. This would bring back fan - favorite bad guys like Frieza and Cell. They could have new powers or forms, making the battles even more intense.

In the fanfic, there could be a plot twist where the Dragon Balls are corrupted. Instead of granting wishes as they normally do, they start causing chaos. This could lead to a race between the heroes and villains to either fix the Dragon Balls or use their new, chaotic power for their own ends. The Z - fighters would have to find a way to deal with this new threat while also fending off their usual enemies.
