The difference between Dragon Ball and Dragon Ball Z

The difference between the two is as follows: the plot is different and the picture quality is different.

1, the plot is different: "Dragon Ball Z" is the sequel to "Dragon Ball", which tells the story after defeating Bick demon, and the "Z" in the title means "end"; Dragon Ball tells the story that the protagonist takes risks everywhere and finally defeats Bick to save the world.

2, the picture quality is different: "Dragon Ball Z" animation is connected from "Dragon Ball" animation, and the story is also adapted from "Dragon Ball" comics, which is a high-definition reprint; "Dragon Ball" animation adds some original plots.
