The new storylines that can be created. For example, a new villain could emerge that requires the combined efforts of both the One Piece and Dragon Ball Z crews to defeat. This could involve battles in different settings from both universes, like fighting on the Grand Line and also in the Hyperbolic Time Chamber. It gives a whole new perspective to the existing story arcs of both series.
Well, perhaps the Saiyans in Dragon Ball Z detect the strong energy from the Devil Fruits in One Piece. Vegeta decides to visit the One Piece world to see if he can gain an edge over Goku. Meanwhile, the Straw Hats are dealing with a new threat that seems to be more powerful than any they've faced before. Vegeta initially clashes with the Straw Hats but then realizes they need to work together. They combine their skills, like Goku's Kamehameha and Luffy's Gear Fourth, to take on the big bad.
The power - up moments. For example, when a Young Justice character witnesses a Saiyan going Super Saiyan for the first time. It's a moment of pure awe and it adds a new level of excitement to the story.
One possible crossover concept is a race or competition that isn't about fighting. For instance, a cooking competition between Bulma and Mumen Rider. It would be a fun way to show the different personalities in both universes. Or perhaps a race between Sonic (from One Punch Man) and Krillin. Another cool idea is a fusion of the two universes' power - up systems. How would it work if a Saiyan could use One Punch Man's power - up methods? It could lead to some really unique and powerful characters.
The crossover manga might have characters from both series interacting in unexpected ways. There could be shared quests or battles that bring out the best in each character. Also, the art style could blend elements of both franchises for a fresh look.
