- Anti-Climax Boss:
- Ricardo was set up to be the Big Bad of the Choujin Olympics arc, but his fight with Mantaro was lackluster and not even the main focus of the volume in which he's defeated.
- General Terror/Akuma Shogun is a better example, since he appears in the last English released volume only to disappear just as quickly.
- Arc Fatigue: 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.
- Awesome Music: The theme tune. ULTIMATE! MUSCLE!
- Broken Base: Was the 4Kids dub of this show an example of one of their very few dubs where they actually did things right, and quite possibly their only dub worth watching over the Japanese original? Or should it be treated with nothing but bile simply because it's a 4Kids dub? To this day, no-one can really see eye-to-eye on it.
- Ensemble Dark Horse: Kevin Mask, Checkmate, Mars, Bone Cold are popular despite their short appearances
- Family-Unfriendly Aesop: The Ricardo and Reborn Ashuraman arcs imply that evil is hereditary, and that attempting to resist one's evil urges is futile. Interestingly, neither Ricardo nor Shiva had a particularly traumatic childhood, unlike, say, Kevin, Hanzo, Bone Cold or Thunder, who all made FaceHeelTurns.
- Fridge Brilliance: In the show we never see Mantarou use the basic Kinniku Buster again after the Mars fight. Why? Because Mars showed off the counter to it on TV. No way any other combatant won't have seen and studied that.
- Germans Love David Hasselhoff: The anime wasn't very popular in Japan, but became ridiculously so in America. One-shot villain Puripuriman/Monsieur Cheeks is also popular in America, to the point that he was used as Mr. Exposition 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.
- Hilarious in Hindsight: 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 (though admittedly, not as much as Kevin).
- Jerkass Woobie:
- In the Ultimate Choujin Tag Arc, it is Thunder of all people as in his backstory, 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. HeelFace Turn by his last appearance on the first series, FaceHeel Turn 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 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 rips it out of apathy...He promptly breaks into tears. Even though he put his pupils through Training from Hell and was an Devil Choujin, you can't help but feel sorry for the guy.
- Nightmare Fuel: 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.
- No Problem with Licensed Games: Both games released in America for the Nintendo 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.
- The Scrappy:
- Terry the Kid. Not only are 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 taking successive levels in jerkassery, but his Scrappy status was really cemented when he tried to unmask Chaos as Kinnikuman Great.
- So Bad, It's Good: Just like with the Spanish dub of the prequel, the series was dubbed in Colombia (a country when Professional Wrestling is not very popular to begin with, compared to 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 constraints.note
- Strawman Has a Point: 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 Bumbling Dad when Mantarou was born, it's not hard to see why Mantarou thought his father fixed his fights.
- Superlative Dubbing: Believe it or not, 4Kids did remarkably well with this show, since the goofy, over-the-top voice acting and Hurricane of Puns 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.
- Too Good to Last: The manga was cancelled in 2011 after the Ultimate Tag arc in favor of a revived Kinnikuman series.
- 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!"
- Even detractors of the dub agree that renaming Gazelleman to Dik Dik Van Dik was one of the dub's best creative liberties.
YMMV / Ultimate Muscle
