Beware Of Spoilers. All spoilers on this page are left unmarked. You Have Been Warned!
The world of underground fights is insane, violent, and cruel, and when you couple that with a globe-spanning conspiracy that has existed for millennia, you bet that there are going to be things that will make you have trouble sleeping at night.
"The Devil" arrives.
General
- Some of the violence in this series is so over-the-top it loops back around and becomes genuinely startling. Even the most serious of gorehounds may have issues with this series. Injuries include limbs twisting at impossible angles, people getting their scrotum crushed (with an anatomically correct diagram showing this in horrific detail), skin warping to impossibly stretched lengths, and tons of very, very nasty compound fractures.
- The very existence of the Worm, a malevolent organization capable of supporting a plot to not only overthrow the Kengan Association but also potentially lead to the deaths of several world leaders in the process, all as a part of what's implied to be something of a side project that even isn't strictly related to their primary objective, which itself is yet to be revealed. They dabble with human "Gu" rituals, where dozens of trainee fighters are sealed inside an underground chamber with just enough food, water and air for one to just barely survive, forcing the group to murder each other if they want to live. This alone is enough to disgust even the amoral Kure Clan.
- Akoya himself. His unhealthy obsession with justice goes to the point that he kills innocent people related to criminals and even victims taken captive by them. He requires Hiyama to restrain him from letting out his bloodlust, and even then, she only minimally curbs it. When she is interrupted or something bad happens to her, he shows his violent nature to the point that he is willing to murder everybody in the vicinity. Both Haruo and Cosmo, who fought him, barely escape with their lives and only got lucky that they lived by getting knocked out or beating him. In Omega, he not only retains his obsession with his own form of justice, but he is independent from Hiyama, which means that he has no reason to even hide his madness any longer. In his fight with Ryuki, he preforms a No-Holds-Barred Beatdown after the latter restrains himself from inflicting a killing blow to the point he needs to be restrained.
Ashura
- The fight between Setsuna and Ren ends with Ren on the receiving end of the Koei Style “Raksasha’s Palm”, an attack that twists the body of those it touches. Setsuna does this right over Ren’s heart, twisting it into a spiral shape and completely deforming it. It was a miracle that he was able to survive that.
- Meguro's death at the hands of Muteba is quite horrifying due to how savage it is. Muteba, clearly not wanting to take chances with the crazy guy who registers pain as pleasure, gouged out Masaki's eyes and ears, then broke his arms and fingers before stomping on his head to break his spinal cord, then finished him off by stabbing his brain through his hollow eye socket.
- Akoya snapping during his fight with Cosmo where he digs his nails in Cosmo's arm to tear it open and follow with a kick that would have put out his eyeball only to then bite him and chew while promising extreme torture. Cosmo can't stop shaking as Akoya proceeds to pin him and break his ribs one by one with his thumb. While the Kengan matches are violent and sometimes fatal, this level of ultraviolence from someone who is a cop in his civilian life done to a fighter that isn't even 20 horrifies the other fighters and spectators.
- The backstories of some of the characters are plain terrifying. The most horrifying being those of Kanoh Agito, who was buried in an underground chamber with a dozen other fighters who were forced to fight to the death until only he remained, Masaki Meguro, who murdered all of his friends at the judo dojo and his father due to an animalistic urge to kill since childhood that was left unsated until the day Muteba finally slew him, and Setsuna Kiryu with his immensely disturbed childhood.
Omega
- Chapter 95 tells us the origins of Wu Hei, the first Wu, who lived 5000 years ago and it's... horrible. The story treats him like a demon who came out of nowhere and even uses "It" Is Dehumanizing. The worst part? He's alive. Well, sort of. While the original Wu Hei died, his will, memories and personality have been copied down in the Wu lineage generation after generation thanks to Huisheng, which consists of Mind Rape on a child telling your life story repeatedly, to every little detail, until he believes he's you. And who carries Wui Hei's soul? Edward Wu, Alan Wu, Solomon Wu, Fabio Wu and a fifth Wu Hei elsewhere.
- Alan Wu's fate at the hands of Raian Kure might be the goriest death in the series so far and shows just how horrific Raian can be with the techniques of the Kure Clan. Alan was butchered in the same way Kratos kills werewolves, being torn in half by the jaws, after having his eyes slashed. Sure it ended up as a loss for his team via DQ, but he sure as hell didn't care as he right afterwards, without missing a beat, ran in after his next target: Edward Wu. Lihito and Mokichi better be glad that he held himself back from doing that two years ago.
- The original Nicolas Le Banner. This man slaughtered a bunch of innocents and his own comrades in a psychotic frenzy while he was serving in the French special forces.
- Fei overclocking himself with the Divine Demon has his body pushed to the absolute limit, causing his veins and eyes burst out in blood as he's reduced to a near skeletal form.
- While it is played for laughs, Xia Ji's encounter and subsequent "interrogation" by Mitsuyo Kureshi and Joji Narushima can be seen as this, especially as this heralds the return of Kureshi's sexual fetish of breaking bones. The idea of having your joints and bones broken by a man who takes noticeable sexual pleasure from doing so, while his stoic friend keeps you immobilised by either kicking your solar plexus hard enough to collapse you or hitting your pressure points so that you are in too much pain to move is a terrifying prospect, lessened only by Xia Ji being completely deserving of it.
- Apparently, in the Two years after the tournament, Worm has started to pull off suicide bomb attacks for unknown reasons. What's worse is just how indifferent their soldiers seem to be to their destiny, with the one we see keeping a bright smile moments before blowing himself and a street full of people sky high.
- Jurota seems to be suffering from some form of psychosis, hallucinating an eyeless Meguro Masaki during his match against Kanoh Agito, and speaking to Meguro's apparition before his fight against Kaolan. Only time will tell whether this obsession devolves into something worse.
