One common theme is the clash of different powers. Naruto has his ninja abilities like chakra and jutsu, while Janemba has his own demonic powers. Fanfictions often explore how these powers interact when they meet. For example, if Naruto tries to use his Rasengan against Janemba's energy blasts.
One popular 'Naruto Janemba fanfiction' could be 'Naruto and Janemba's Unlikely Alliance'. In this story, Naruto might find himself in a strange dimension where he encounters Janemba. The plot could revolve around Naruto trying to understand Janemba's powers and finding a way to either defeat him or make him an ally. It's an exciting read as it combines the unique elements of the Naruto universe with the otherworldly nature of Janemba.
It depends on your preferences. If you like action-packed and fantasy-themed stories, then you might find the DBZ Fighters story enjoyable. It has exciting battles and interesting character arcs.
It's a bit tricky to say for sure. The number of DBZ manga can vary depending on different editions and compilations. But you can find detailed information on dedicated manga websites or forums.

In DBZ Vegeta and Bulma fanfiction, there can be alternate universes explored. Maybe in one universe, they meet under different circumstances. For instance, instead of Vegeta coming to Earth as an enemy, he could be an ally from the start. This would completely change the dynamics of their relationship. It could lead to a more romantic and less combative start to their relationship, and the fanfiction could explore how this different beginning affects their future together.
One reason could be that the fanfiction has reached a natural conclusion for most of the writers. They may have told the stories they wanted to tell within the DBZ universe. Moreover, the competition from other forms of entertainment, such as new and popular anime series, could be drawing away both the authors and the readers. So, with fewer people interested in reading and writing DBZ fanfiction, updates become scarce.
