And Dragonball was inspired by martial arts movies. Like literally Toriyama came up with the idea from watching kung fu movies while in a funk over Dr. Slump being kind of boring for him to write after so long.
Add in some Journey to the West and other Chinese novel inspirations alongside, funnily enough, old Disney movies (apparently he loves 101 Dalmatians) and you have Dragon Ball.
It all comes full circle.
