* AntiClimaxBoss: Richardo was set up to be the BigBad of the Choujin Olympics arc, but his fight with Mantaro was lack luster and not even the main focus of the volume in which he's defeated
** General Terror/[[spoiler:Akuma Shogun]] is a better example, since he appears in the last English released volume only to disappear just as quickly.
* ArcFatigue: They've been in the past since 2005!
** To put it in context, Yudetamago has spent more time on this single tournament arc than any other arc they've done, including arcs from the original {{Kinnikuman}}. Which is sad, really, considering that they were pretty good at avoiding this trope.
** Technically speaking, the Tag Arc is its own series
*** Even so, the same storyline has been going on for six years.
* [[InvincibleVillain Boring Invincible Villains]]: Thunder and Lightning. They've gone through almost the entire tag arc only being mildly inconvenienced by the heroes with the sole exception of ''Geronimo'' of all people destroying their bell. Even other, very strong ''villains'' are jobbing to them!
** [[spoiler:In the finals, this has been apparently subverted in the case of Thunder of having serious HiddenDepths since we get a load of his FreudianExcuse to explain why he was evil due to him being the result of his father ''raping'' his mother.]] Nothing for Lightning though
* EarWorm: ''With my rice I like to have some cow cow cow/ Tastes so very good I don't care how how how...''
** "Ga-ga-gan ga-ga gan (Do the Muscle!) Zu-ba-ba ba-ba ban (Hustle Muscle!)"
** [[http://www.youtube.com/watch?v=2TD7SSjVPl4 ULTIMATE! MUSCLE!]]
* EnsembleDarkhorse: Kevin Mask, Checkmate, Mars, Bone Cold are popular despite their short appearances
* FamilyUnfriendlyAesop: Ricardo's story and the Demon Seeds arc seem to have the message that you're either born good or born evil, and going against it is impossible.
* GermansLoveDavidHasselhoff: The anime wasn't very popular in Japan, but became ridiculously so in America. One-shot villain Puripuriman/Monseuir Cheeks is also popular in America, to the point that he was used as MrExposition throughout the remainder of the dub after his only appearance in the show proper.
** The anime was so popular in America that another season (cover the Choujin Olympics Revival) was commissioned by 4Kids.
* HilariousInHindsight: Anyone who's read the original series might find it funny that Kevin Mask constantly switches sides, since Robin Mask had a habit doing so in the first series[[note]] Though admittedly, not as much as Kevin.[[/note]]
* InternetBackdraft: Known as "The Kinnikuman Incident". Fans were not pleased at the fact that Akira Kamiya did not reprise his role as Kinnikuman in this series. It got worse when in an interview, Kamiya himself said that he wasn't even ''offered'' the role.
* JerkassWoobie: In the Ultimate Choujin Tag Arc, it is [[spoiler:''Thunder'']] of all people as in his backstory, [[spoiler:he discovers that the reason why his mother was scared of him when he was a kid was because his father, a Time Choujin like him, attacked his home village and even ''raped'' his mother which explains why he was born! This caused him to run away from home crying. You got to feel sorry for the guy.]]
** Sunshine. HeelFaceTurn by his last appearance on the first series, FaceHeelTurn by the time Nisei came around because his comrades and friends left him one by one, but he still respected the Idol Choujin despite being enemies. And [[EvenEvilHasLovedOnes he always carried with him a photo of his companions]] and which is also the only remaining memory he has of them. So when Checkmate [[KickTheDog rips it out of apathy]]...He promptly breaks into tears. Even though he put his pupils through TrainingFromHell and was an Devil Choujin, you can't help but feel sorry for the guy.
* MoralMyopia: Peshango's reaction to Ricardo's true nature, to immediately attempt to kill the man for being a by-birth Evil Choujin, is certainly [[UnfortunateImplications concerning]], along with the attitudes of Ricardo's fellow students. And the discrimination was BEFORE it was revealed he killed the old man.
* NightmareFuel: Hydrazoa can impale his enemies with his vertebrae, Hanzo cuts people's faces off and there's Bone Cold's technique of causing the ribcage to shoot out of his enemies.
* NoProblemWithLicensedGames: Both games released in America for the GameCube and Playstation 2 respectively are considered very fun wresting games with good controls and a great selection of characters. Some consider them the best wrestling games ever made.
* TheScrappy: Terry the Kid. Not only a great deal of most of his moves basically Terryman's moves, which are already criticized for being lame, he also tries to deny the fact that he's nothing like Terryman and that he performs the moves at different angles and timing, which isn't fooling anybody.
** Canadianman's getting his fair share of hatred for [[TookALevelInJerkass taking successive levels in jerkassery]], but his Scrappy status was really cemented when he [[spoiler: tried to unmask Chaos as Kinnikuman Great.]]
* StrawmanHasAPoint: Anybody who's read {{Kinnikuman}} would agree with the old Choujin that Mantarou is ''completely'' out of line for assuming that Suguru's fights were fixed. But then, you learn that after the last arc in the original series, Suguru annulled his fight records and burnt every video of his fights. The only photographs of him left was when he was still a complete coward, so combining with the fact that Suguru became a BumblingDad when Mantarou was born, it's not hard to see why Mantarou thought his father fixed his fights.
* SuperlativeDubbing: Believe it or not, 4Kids did remarkably well with this show, since the goofy, over-the-top voice acting and HurricaneOfPuns fit the tone of the show ''perfectly'' (After all, the series is an action-comedy, whose origins are from a manga that was originally a gag manga). It's commonly cited as one the few anime that 4Kids managed to not screw up.
** SoBadItsGood: On the other hand, just like with the Spanish dub of the prequel, the series was dubbed in Colombia (a country when ProfessionalWrestling is not very popular to being with it, compared with Mexico) and it suffers for it, although this is justified, as 4Kids were unable to dub it in Mexico (compared with their other series they dubbed before) due to budget constrains.[[note]]Dubbing in Mexico is more expensive than dubbing in Colombia and other South American countries.[[/note]]
* TooGoodToLast: The manga was cancelled in 2011 after the Ultimate Tag arc in favor of a revived ''{{Kinnikuman}}'' series.
* UnfortunateImplications: Kinnikuman Great's mask.
* VillainSue: Thunder and Lightning, while most of the villains are strong, they have regeneration, body manipulation and [[spoiler: the ability to stop time]]
** Shivano/[[spoiler: Ashuraman]] and Boltman are lesser, but still notable examples
* {{Woolseyism}}: Some of the dialog's meaning was changed completely. Kid Muscle (to Roxanne): "Bring your two friends! We could have a foursome. (long pause) ...for golf!"
