For the most part, no. Manga creators usually want to deliver a coherent and focused story without the distraction of filler episodes. This helps maintain the integrity and appeal of the series.
One great 'oc dbz fanfic' is 'The Saiyan's New Hope'.

A great DBZ crossover fanfiction often has well - developed characters. When DBZ characters cross over into another universe, their personalities should remain true while also adapting to the new setting. For example, if Goku is in a Naruto crossover, his love for fighting and his naivete should still be there but in a way that fits the Naruto world. Good pacing is also key. The story should move along smoothly, not be too rushed or too slow.
One great place to start looking for the best DBZ crossover fanfiction is on fanfiction.net. It has a vast collection of different crossovers involving DBZ.
