Dragon Ball, Kinnikuman Recommendations
Both start out as gag mangas but slowly turns into more serious fighting manga. Both are classics that you will see referenced alot in other works.
Both series focus on over the top comical feats during the first few story arcs, before becoming more serious and featuring fights in which the main threats of the previous story arc is quickly surpassed. The main characters of both series are also aliens who are somewhat "dumb" in some area, which aid in making the other members of the cast look better. The use of the Chojin Olympics during the earlier arcs of Kinnikuman may have also been the inspiration for the Tenkaichi Budokai in Dragon Ball.
80s superpower manga which started as a gag manga originally then as time went on, they became intense battle manga with a gigantic cast where frequent deaths are solved with revivals.
Both were very popular Weekly Shounen Jump manga and feature a protagonist who isn't very intelligent and really likes to eat, as well as many characters who start as villains but then turn out good and help the heroes.
This is a shonen trope setter. This is Dragon Ball Meets Wrestling. It has Surreal and Epic fights, Colorful characters, and grows with it's audience (all just like Dragon Ball). I wouldn't be surprised if it inspired if it inspired Akira Toriyama with some aspects of the series. If you like Dragon ball in an form, you owe it to yourself to Read/Watch Kinnikuman.
