One interesting fanfiction could be where Cell somehow ends up in the Naruto universe. Maybe he's a new type of enemy that the ninja have to face. It could bring a whole new level of danger as his powers are different from the normal jutsu - based attacks in Naruto.
Cell's regeneration ability could be given to a character in Naruto. For instance, if Sasuke had this power, it would make him even more formidable in battles. He could lose an arm and quickly regenerate it, just like Cell.
One interesting aspect could be the different character interpretations. In fanfiction based on DBZ Cell Games footage, authors might explore new sides of Goku, like his internal thoughts during the intense battles. For example, they could delve into how he really felt facing Cell's powerful forms.
By having unique plot twists. If the fanfiction has a plot that no one has thought of before, like a time - traveling element where a future version of a character comes back to change the outcome of the Cell Games, it will attract more readers.
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.
