One of the most interesting aspects is the potential for new character development. Characters from both Naruto and Dragon Ball Z can grow in ways they never could in their original series. For example, Naruto could learn about the concept of Super Saiyan and try to achieve a similar power - up, which would change his view of power and his own abilities. Similarly, Goku could be introduced to the idea of ninjutsu and incorporate it into his fighting style. This kind of cross - pollination of ideas and growth for the characters makes these crossovers really appealing.
