One interesting concept could be a battle between Goku and Hulk. Their raw strength and different ways of using power would make for an epic showdown. Goku's martial arts skills combined with his ki blasts against Hulk's increasing strength as he gets angrier.
A third concept could be the Z - Fighters learning about the Infinity Stones from the Marvel Universe. How would they react to such powerful artifacts? And how would they incorporate this knowledge into their own power - up strategies?
One interesting concept could be the combination of jutsu from Naruto and ki attacks from DBZ. For example, a character might use a Rasengan infused with ki to create a super - powered attack. Another concept could be the interaction between the different power - up systems. In Naruto, there's chakra control and the various forms like Sage Mode, while in DBZ there are Super Saiyan forms. A crossover could explore how a ninja might train to achieve a Saiyan - like power - up, or vice versa.
One interesting concept could be the crossover of DBZ characters with characters from other popular anime. For example, a crossover with Naruto characters might lead to some epic battles between Goku and Naruto. They could exchange fighting techniques and learn from each other.
One interesting concept could be the characters from Gravity Falls getting Saiyan powers. For example, Dipper could discover he has latent Saiyan abilities and start training like Goku. This would change his dynamic in the Gravity Falls world as he tries to balance his newfound power with the mysteries of his hometown.
One interesting concept could be the power levels. In DBZ, characters have extremely high power levels through ki. In Star Wars, the Force is a different kind of power. A crossover could explore how these two power systems interact. For example, a Saiyan using the Force or a Jedi using ki techniques.
In dbz gamer fanfiction, an interesting idea is the introduction of new races or characters inspired by gaming tropes. They could have unique abilities that interact with the existing DBZ powers, creating fresh and unexpected storylines.
Some fanfictions focus on the idea of training in the Xenoverse. They might come up with unique training regimens for the characters. For example, a fanfic could have Vegeta training under a new master who has a completely different fighting style. This can lead to Vegeta developing new powers and techniques. Also, the concept of a new threat to the universe that is not related to the usual villains in Dragon Ball Z can be exciting. It forces the characters to adapt and find new ways to fight.
One interesting concept could be the idea of self - inserted characters having unique powers that interact with the existing DBZ power system. For example, a self - inserted character might have a power related to time manipulation in a world where the Saiyans' strength and energy blasts are the norm.
One interesting concept could be the fusion of Pokemon powers with the energy - based attacks in DBZ. For example, Pikachu might be able to use its electric attacks in a way similar to Goku's Kamehameha, but with an electric twist. Another concept could be the Pokemon trainers having to face off against DBZ villains, and they'd have to strategize using their Pokemon in a completely different battle environment. Also, the idea of Pokemon evolving in a way that's influenced by the ki energy from DBZ, like evolving into a more powerful form when exposed to a certain level of ki.
The power - scaling is also an interesting aspect. DBZ is known for its extreme power - scaling, with characters reaching god - like levels of strength. In RWBY, the power levels are more grounded but still significant. In the fanfiction, the writers might explore how the RWBY characters would react to the overpowering strength of the DBZ characters. Would they be intimidated? Or would they strive to reach those levels of power through their own means?
One interesting concept is how time travel affects character development. For example, a character might go back in time and change a key event, which then alters their future self in unexpected ways. Another concept could be the exploration of alternate timelines. Maybe a character's time travel creates a whole new reality where different battles play out and relationships shift.
