Summary
Among the various action manga to be published inWeekly Shonen Jumpover the years, two of the most iconic manga from its library are Akira Toriyama’sDragon Balland Yudetamago’sKinnikuman. Both were among the most popular manga running in the 1980s, and thanks to said popularity, they’ve become some of the most influential manga of the past several decades, as well, especiallyDragon Ball.
Dragon BallandKinnikuman’s popularity sparked a rivalrybetween the stories and their respective creators, ending with a clear winner asDragon Ball has becomeone of the most popular and successful anime franchises in the world whileKinnikumanis largely unknown outside of Japan.

As it turns out, though,Dragon BalleclipsedKinnikumanin popularity so much that it played a part inKinnikuman’s ending; it’s a story that’s equal parts engaging and tragic, but as any fan ofKinnikumanknows, there was certainly a happy ending for the series later down the line.
Kinnikuman’s Writer Felt Intimidated By Akira Toriyama Well Before Dragon Ball
The Series That Kickstarted An Unfortunate Rivalry
Well beforeDragon Ball’s official debut inWeekly Shonen Jump, the writer half of Yudetamago, Takashi Shimada, already felt intimidated by Toriyama thanks to his debut work,Dr. Slump. Both manga were focused on comedy, butTakashi Shimada felt intimidated byAkira Toriyama’s comic book-style artworkand more sophisticated humor, andDr. Slumpgetting an anime after only a year when it tookKinnikumanfour years only made that worse. This caused a lot of bickering between them, and that didn’t stop for all the time they were both serialized inWeekly Shonen Jump.
How Dragon Ball Beat Kinnikuman At Its Own Game
Dragon Ball Was The True King Of Martial Arts Manga
Dragon Balldidn’t debut until 1984, five years intoKinnikuman’s run after it was already a major franchise, but with its martial arts action and the same great art and comedy that madeDr. Slumpa hit, it wasn’t long beforeDragon Ballstarted matchingKinnikumanin popularity. That reached its peak in 1985 with the introduction of the World Martial Arts Tournament, as not only didDragon Ballbecome even more popular, butDragon Ballwas now making a name for itself with martial arts tournaments, one of the central gimmicks ofKinnikuman’s story.
It was one thing forDragon Ballto be more popular thanKinnikuman, but with Toriyama’s manga doing its own take on martial arts tournaments, there was now a sense that there was nothingKinnikumanwas the best at, a thought that didn’t sit well with Takashi Shimada. That train of thought emerged while Shimada was recovering from a back injury, and when it all came together,Takashi Shimada decided to endKinnikumanbecause of how much betterDragon Ballwas. The series eventually concluded in 1987, two years afterDragon Ballintroduced the World Martial Arts Tournament.

The most tragic part about Takashi Shimada and Akira Toriyama’s rivalry was that their relationship wasn’t always so strained. FollowingAkira Toriyama’s tragic passing in early 2024, Takashi Shimada talked about how he and Akira Toriyama used to be good friends,but he let his jealousy over Toriyama’s success ruin their friendship, and the two never reconciled their differences in the years to follow.Dragon Ball’s popularity ended not only a popular manga but a good friendship, as well.
Kinnikuman’s Creator Found New Hope In Its First Sequel, Ultimate Muscle
Serialized In Weekly Playboy 1998-2011
FollowingKinnikuman’s ending, Yudetamago published three more stories inWeekly Shonen Jump:Here Comes Phantom Kid!,Scrap Sandayu, andKick Boxer Mamoru, none of which were popular and were each canceled within a year. By 1991, Yudetamago was under so much pressure from fans to both followKinnikuman’s success and compete withDragon Ballthatthey stopped working withWeekly Shonen Jump, entirely, with their next few stories each going to competing publishers. Unfortunately, they didn’t have much success with that, either, as their stories outside ofShonen Jumponly lasted around two years before being canceled.
In 1998, Yudetamago returned toKinnikumanwith the first official sequel,Kinnikuman Nisei, better known worldwide asUltimate Muscle. Building off the legacy of its predecessor,Ultimate Musclewas a big hit in its own right and ran for 13 years.Takashi Shimada was so moved byUltimate Muscle’s initial success that he cried, as it made him realize his fans never abandoned him.Ultimate Musclewas never as big a success asKinnikuman, but the fact that it was successful at all still meant a lot to Shimada, overall.

Ultimate Musclewas also the first time theKinnikumanfranchise found true success outside Japan. While the anime wasn’t that popular in Japan and ended unceremoniously on a filler arc,Ultimate Muscle’s anime was a major hit in the Western worldthanks to 4Kids Entertainment giving it a hilarious gag dub, and it was so popular that they commissioned a second season to give it a proper ending. None of that was on the level ofDragon Ball’s success, but it was the first timeKinnikumanhad even remotely similar popularity, and that made all the difference.
How Kinnikuman Finally Came Back & Became Bigger Than Ever
Kinnikuman Is Finally In The Spotlight
Ultimate Muscleended in 2011, and immediately after, it was announced that another sequel toKinnikumanwould start that same year, this one being a direct continuation ofthe originalKinnikumanmanga. With the characters people grew up with back in focus and a story more consistent with the original while still expanding on the wider lore,Kinnikuman’s new sequel series made the franchise the most relevant it’s been since the original series, and with it recently receiving a new anime inKinnikuman: Perfect Origin Arc, that’s bound to only increase even further, especially on an international level.
The history of the originalKinnikumanseries is sad to think about, especially with how it affected Takashi Shimada and his relationship with Akira Toriyama on such a personal level, but if the wider history of the franchise says anything, it says thatKinnikumanhas always had a place among the biggest action-oriented anime and manga, even if it could never surpassDragon Ballin that regard. There’s no way to know what would have happened if Shimada hadn’t letDragon Ball’s popularity get to him, but at the very least,Kinnikuman’s current popularity and lasting legacy are still worth marveling at.

From the creative mind of Akira Toriyama, Dragon Ball is a mega multimedia franchise that spans back to the 1980s.

Dragon Ball was the initial starting animated series that followed the adventures of the young Son Goku as he sought after the Dragon Balls. These mystical orbs would grant the wish of any who gathered them together. Then, the series would branch off into the immensely popular Dragon Ball Z, which followed Goku as an adult and featured high-intensity battles and Goku’s never-ending search to be the strongest.
