By Sanrio standards, the second and third seasons of the Netflix series Aggretsuko could be considered one of the company's bloodiest works. While the company rarely shows any depictions of bloodinanyof their works. note Blood was shown once in an episode of Onegai My Melody. Blood is shown twice in the second season. The first is when Retsuko gets a bloody nose when she falls on her face while searching for Anai. The second is at a driving school, where Retsuko is taking a class so she can get her driver's license. One class lecture has her being taught about driver safety, and one of the slides in the slideshow features a possibly deceased bird complete with a bloody smashed windshield. Retsuko leaves the class in shock and feels nauseated. And then in the third season, Retsuko almost gets killed by a stalker, also involving blood.
It should be noted that this only applies to their TV series. Sanrio's earlier films from the 70s and 80s had no qualms showing blood, most notably Ringing Bell and Be Invoked. And unlike Aggretsuko, which is aimed at adults, these were children's movies!
The Birdy the Mighty remake manga, a Seinen series is more violent and gruesome the original, which was a Shonen series. Likewise, Season 2 of Decode was more violent than the OVA and Season 1, as it involved being more violent than Season 1, as Season 2 features dismemberment, heads being crushed in, and at one point, a character getting his eye stabbed.
Black Lagoon already was a very violent series with gunshots and blood aplenty, but the OVA adaptation of El Baile De La Muerte arc turns up the violence even more with things to bodies disintegrating into Pink Mist, chainsaws going through a grown, alive man's torso and everything in-between.
Promptly after its anime adaptation ended, Bleach has seen a significant rise in gorier violence and deaths, adding to the noticeably Darker and Edgier tone it took beginning with the final arc.
Blood-C, compared to the previoustwo series in the franchise, where the blood and gore are significantly upped, and far more detailed.
The manga adaptation of Breath of Fire IV is considerably bloodier (and gorier) than the original video game, especially compared to international versions.
Admittedly, a big chunk of this is because Breath of Fire IV (the game) suffered particularly severe Bowdlerization, especially in the international releases. note A notable example included an Aborted Arc featuring Woobie, Destroyer of Worlds Fou-lu decapitating usurper Soniel with the very Evil Weapon Soniel had tried to use to kill him. In non-Japanese non-Playstation releases, this scene ended up completely cut from the game, despite the fact it was depicted only via silhouette. Also, the manga was published in Comic Blade Avarus which is geared towards young adult women.
The manga did a major Take That! in regards to that Bowdlerized scenenote involving Soniel's decapitation, not only making it Bloodier And Gorier but making the original moment worse.
Cells at Work! CODE BLACK gets much grislier than its shonen counterpart, fitting its Dangerous Workplace themes. While Cells at Work! doesn't shy away from having its own share of blood and guts, they reserved that for the invading bacteria. In CODE BLACK, the body is so dysfunctional all cells have a chance to end up as corpses, and a lot of them can and will die on the job. As a result, CODE BLACK gets a rare 18+ rating in the US.
Danganronpa 3: The End of Hope's Peak High School compared to the other Hope's Peak Saga games that preceded it. Most deaths happen on-screen rather than being shown after the fact, the murders are brutal, and the Future portion of the series frequently features red blood instead of the franchise's usual pink. Rather than the over-the-top minute-long executions featured in the games, the anime's lone execution is the central focus of a third of an entire episode, and pretty much is Torture Porn where the victim slowly gets more bloodied by traps until Chiaki outright gets impaled at the end.
Devilman is already a violent and grotesque affair back to its 70's roots. But the alternative sequel Amon cranks the violence even higher up, showing more blood, gore and nastiness in its 45-minute run than the whole TV-series did in 39 episodes. Similarly, DEVILMAN crybaby cranks up both the gore and sex, combined with an overdose of Deranged Animation.
The Dragon Ball franchise definitely fits the bill. When you compare the tone and nature of Dragon Ball to that of Dragon Ball Z, it's night and day. Granted, Dragon Ball became violent in its final arc (King Piccolo), but in Z the blood and gore are off the scale: limbs being torn off; characters regularly coughing up rivers of blood; children being tortured, murdered in cold blood or paralyzed; mass genocide of entire races; people being decapitated... and the Namek Saga gets even worse. On top of that, the manga is even more violent: if anybody were to explode it would start raining blood and if anybody's head was crushed or destroyed (which happened very frequently), you would see parts of their brain splatter all over the place.
Mocked in the unaired final episode of Excel♡Saga, appropriately titled "Going Too Far". Hyatt coughs up enough blood to flood the planet.
One would never have expected that Fist of the North Star could ever be made bloodier, but New Fist of the North Star/Shin Hokuto No Ken shows more splattering blood and brain matter in more loving detail than anything else from this series, before or after.
Hell, compare the TV series to the 1986 movie. For the first time, Toei Animation got to show all the Ludicrous Gibs the original manga had to offer, and with an impressively high budget (by anime standards) to boot! That is, until Moral Guardians forced the producers to blur, tint, and cut out any gore that wasn't just High-Pressure Blood or a Freeze-Frame Bonus.
Hellsing has both an anime and an OVA, the second of which follows the manga's plot more closely. While both series have their share of blood and gore, the OVA takes Ludicrous Gibs to another level entirely, which in of itself gets much more grisly as the series goes. Compare Alexander Anderson's attack on Seras at the beginning to Zorin Blitz's death. Hellsing isn't just bloodier and gorier than other series, it's bloodier and gorier than Hellsing, too.
The manga adaptation of Inazuma Eleven has more blood and detailed injury scenes than in the original.
The Legend of Zelda: Twilight Princess (2016) leans to the game's darker, more naturalistic aesthetic by removing the bloodlessness from the series' normally Bloodless Carnage, which, when applied to a game about stabbing things, means quite a lot of blood.
Lupin III is a series generally known for its lighthearted antics and Bloodless Carnage; even the more adult manga and versions of the show generally avoid the gorier aspects in favor of stylized violence. Therefore, most Lupin fans found the appropriately named Goemon Ishikawa's Spray of Blood, focusing on Lupin's samurai companion, rather shocking in how it averts the old style hard, and is full of severed limbs, High-Pressure Blood, and gruesome injuries.
Magical Record Lyrical Nanoha Force, in addition to being Darker and Edgier, also ramped up the blood and gore. Where previous seasons kept the casualty count of Innocent Bystanders off-screen, Force introduced the new villains by having one of them leave a bloody trail of dead nuns. Where previous seasons reserved bloody battles for Wham Episodes or final battles, every battle in Force has had one or both sides being covered in blood or losing limbs without a Gory Discretion Shot. Where the bloodiest thing that happened in the previous seasons is impalement, the Force season has the Eclipse Infection as its main focus, which makes people undergo Body Horror that ends with them exploding in a shower of blood and brains.
While the Nanoha franchise has never shied away from blood before, Detonation is by far the most visceral carnage seen so far (with the possible exception of Force), which includes the slaughter of the Planet Restoration Committee, the aftermath of Nanoha and Fate blowing Maxwell apart, and Nanoha's battle with the last Iris Unit that ends with her missing a arm.
Gundam SEED and Gundam 00. While the franchise has never been a stranger to violence (being a relatively pessimistic, down-to-earth Humongous Mecha vehicle), these two shows were where we really got to see the horrifying effects of its signature immensely powerful sci-fi weaponry, as characters were torn apart by energy beams or simply popped like balloons by microwave emitters. Even the interpersonal violence became a little more visceral, with gunshot wounds causing their victims to twitch and bleed copiously. And then there's Gundam: Iron-Blooded Orphans, which is possibly the first Gundam series to be given a TV-MA rating, and features such charming fates as being crushed by your own cockpit.
The anime adaptation really turns up the blood involved in the fights. In the USJ arc, Aizawa and Shigaraki's injuries are particularly more gruesome than in the manga, full on with pools of blood oozing out of them. Any injuries given are also depicted in loving detail.
Negima! Magister Negi Magi generally averted Bloodless Carnage, but the Stealth Sequel series UQ Holder! amps up the violence. In Negima seeing a major character lose an arm was generally a huge shock. In UQ Holder!, the protagonist gets dismembered in the opening chapter, he wins his first fight by letting his opponent decapitate him, and later on literally has his heart punched out of his chest. Good thing the series is about immortals.
The second Rebuild of Evangelion movie has the Angel Sahaquiel's death go from a standard enormous explosion to transforming into a tsunami of blood that engulfs Tokyo-3.
Played for morbid laughs in One Piece. Roronoa Zoro loses progressively more blood in each of his major one-on-one fight scenes as a subtle Running Gag. Keep in mind that, according to Word of God, he had already lost nearly twice as much blood as a human body can survive through during his fourth fight. The pool of blood seen in the aftermath of his fight with Kuma takes this up a notch. Although it stops being funny when it turns out he didn't completely recover after that last incident...
The manga in general, when compared to the anime and games. See the infamous scene where an Arbok gets non-lethally chopped in half for an example.
While battles generally still aren't ultra violent and bloody, the six generation stands out with Rayquaza sucker punching Zinnia in the gut hard enough for her to vomit copious amount of blood, and the amount around Lysandre's head when he fell from a serious height into some spiky rocks.
Due to the monochrome color it's hard to tell what's blood and what's bruising, but Pokémon: Diamond and Pearl Adventure! is more violent than its source game. It's especially noticeable during the Hareta versus Mitsumi battle.
Psycho-Pass: The Movie is free from the censors put up by TV networks where they can show lots of people getting down brutally. While it's known that being blown up by the Dominator's Lethal Eliminator mode is gruesome, the movie shows the actual remains of it.
The Ranma ½ movies and TV specials are a lot bloodier than the show, notable examples include in the first movie Happosai gets stabbed in the neck with a kunai and a lot of blood flows from the wound and Monlon entangles Ranma in her lute strings shredding one of his arms and causing a lot of blood to spray.
Sailor Moon: The manga version than the 90s anime.
The manga of Sands of Destruction doesn't shy away from blood at all, whereas both the original game and anime adaptation used plenty of Bloodless Carnage (despite the heroine's BFS).
The 2021 anime adaptation of Shaman King is right from start bloodier and more violent than one from 2001, to say nothing about bowdlerized version released on 4Kids channel.
In-Universe, the virtual worlds of Sword Art Online become this for the Alicization arc. Justified in that the first two seasons dealt with virtual videogames, while Underworld is a more hyper-realistic virtual simulator designed for combat purposes (which includes having no pain absorber), hence why the wounds the characters suffer in it are a lot nastier.
Tengen Toppa Gurren LagannLagann-hen was pretty bloody compared to the original series. Simon coughs up blood twice, the Tengen Toppa Gurren Lagann bleeds, the Anti Spiral bleeds... It probably helped that Gainax wasn't bound to the Saturday morning timeslot.
Speaking of Higurashi, the manga compared to the anime. It's much gorier (but is still aimed at teens).
Most of the individual arcs of both of these shows get Bloodier and Gorier over time.
X1999 is already a very gory manga, but The Movie takes the Gorn up a notch, especially with Kotori's death, which depicts her organs being splattered right out of her body. Inverted with the TV adaptation, which while more faithful to the manga's story and characters, tones down some of the more violent scenes. (Kotori's aformentioned death, and the infamous Eye Scream are both turned into a Gory Discretion Shot.)
Yuki Yuna is a Hero's prequel Washio Sumi Is a Hero features this for plot related reasons. Its protagonists get physically injured, despite being even younger than Yuna's team, because the Fairy Companions aren't around to block all attacks (in fact, the fairies were introduced to avoid Heroes dying). The girls end up battered and beaten after each fight. Gin's death scene is especially bloody.
