Heat Guy J could be described as a crime-drama anime, in the same way that Ghost in the Shell could be described as a crime-drama anime. Daisuke Aurora, a laid-back Special Services officer, and his powerful android partner J, known as the Heat Guy because of the need to vent superheated air from his body after periods of action, work to solve crimes and catch the more dangerous criminals that plague the city of Judoh.Supporting cast include Clair Leonelli, Ax-Crazy villain and boss ('Vampire') of the Leonelli crime family; Ken Edmundo, perpetually irritated crime scene investigator; Kyoko Milchan; accountant for the Special Services Division who briefs Daisuke on his cases, and Boma, mysterious swordsman searching for someone called 'Usagi'.The 26-episode series was produced by Satelight. It was licensed in the United States by Geneon, in the United Kingdom by Manga Entertainment, and in Australia and New Zealand by Madman Entertainment. Infamous for how much Geneon paid for it (as much as Funimation paid for Fullmetal Alchemist) and how little it sold.
After the End: A very subtle example, but the reason the world is divided into seven cities is because war (using the Celestials' technology) nearly drove humanity to extinction.
Anachronism Stew: In this high-tech world, Daisuke still has a TV with rabbit ears and knobs, and Clair has a rotary phone.
Abnormal Ammo: Red Caps - exploding bullets. Also the bullets (effectively miniature cluster bombs) fired by Luka's illegal pistol, which are capable of blasting J apart so that only his head remains intact.
Blue Caps essentially KO targets with electric shocks.
Badass Normal: Daisuke can survive a fight with an android, singlehandedly beat up a gang of men exploiting women, and even match Boma in a swordfight for a while. Clair Leonelli, though merely for the fact that he fears nothing - he lacks Daisuke's extraordinary physical prowess. Giobanni Gallo is this for walking into the Vita headquarters and shooting Noriega in front of a room full of Leonelli Family mobsters. With one arm in a cast.
Hell, just about anyone who isn't an android or a Transhuman like Boma is this.
Bare-Fisted Monk: J has no special weapons built into his body. His means of fighting is dead simple: punch the enemy's lights out. Given his awesome android strength, endurance, and precision, this actually suffices most of the time.
Bishōnen: Shun Aurora, Clair Leonelli, Michal and Serge Echigo. Daisuke is a borderline case.
Contemplate Our Navels: Daisuke when he's lying around on the sofa pondering about what's really going on; Shogun (pretty much every single thing he says is this); Clair, especially as Giovanni gets ready to assassinate Shun and don't even get started on Boma.
Cool Bike: Daisuke's motorbike not only looks awesome, but can transform into a jetski. It can also reconfigure so J can drive it, letting it run even faster then human reflexes allow.
Death by Childbirth: This was the fate of Clair's mother, according to Lorenzo. Antonia also grew up without a mother, which suggests that this trope may have been involved, but we don't get enough information to say for sure.
Dysfunction Junction: From what we see, Kyoko may be the only major character who actually has a healthy, functioning family.
Easily Forgiven: At the end, Shun is still working for the city. And after having the president shot, too! Clair is also free, but goes through some serious trauma like his only friends dying for him, so, it evens out? I guess?
Evil Laugh: Clair has one of these. Noriega gets to do this just before he gets shot to pieces.
Ken Edmundo, since it looks like Dryden lost his glasses.
Fake Memories: Boma never had a sister called Usagi. Usagi was his best friend's long-dead little sister, but Boma subconsciously altered his own memory of her when the Beast Master attempted to brainwash him in prison.
Fate Worse than Death: Boma's city state has no death penalty. Instead, criminals serving life-sentences are genetically and surgically altered so that they have the bodies of humans, but the heads of animals. Not only that, but they are subjected to brainwashing and other forms of torture. The idea is so they'll regret every day what they did.
Fangirls: The three girls always hanging around Daisuke.
Fan Disservice: At one point in the series, when Clair hides out in the slums, a couple of guys approach him and start stripping off his shirt (ostensibly because it's valuable, but that's probably not the impression most fans got). It's more heartbreaking than anything else, considering Clair just sits there and takes it.
Fanservice: Several relatively subtle examples exist: there's the generally Stripperific outfits certain characters wear, the outfit Kyoko wears when she goes to rescue Daisuke, which is much skimpier than her usual fare, the low necklines worn by well-night every single woman in the series even if their clothes are otherwise relatively modest, a shot of Antonia sunbathing—as well as at least a couple scenes of Daisuke without his shirt on (one scene shows that he sleeps in nothing but his boxer shorts), and pretty much everything about Boma.
Faux Action Girl: Phia is supposed to be Shogun's assassin yet is never shown actually fighting on screen.
Fighting from the Inside: J desperately resists when Shun uses the override code to force him to try to kill Giovanni and Daisuke.
Filler: Filler episodes abound, mostly for character development; a lot of fans were turned off by the fact that the plot took so long to finally come together. Thankfully, however, the fillers are not too horrible to watch,they were just not very relevant to the central plot or central characters. And even more thankfully, the plot eventually does tie together, even using small details from the filler episodes.
Finger in the Mail: A Corrupt Politician kills Ian when the latter was caught spying. The guy then cuts off Ian's hand and sends it to Ian's boss (and friend), who then declares war on the senator.
Good Colours, Evil Colours: Similar to the "good hat bad hat" dichotomy of Westerns, Daisuke (the good guy) wears white pants and has blond hair, while Clair (the bad guy) wears black pants and has black hair. This only goes so far in the series, however.
Good Smoking, Evil Smoking: Particularly in the manga, but even in the anime. Smoking has been illegalized in Judoh, so unsurprisingly, many (though not all) of the bad guys are seen to smoke. These include various Mooks, Clair's sexy scientist girlfriend Trinity in the manga, and even Shun can be briefly seen a time or two with a cigarette.
Gondor Calls for Aid: During the battle of Kabuki Road, every major figure from the entire series shows up to bail out the mob.
Gory Discretion Shot: Ian is murdered and his severed hand with his Phi Beta Kappa ring on it is sent back to Clair. All we see is the look of horror on Clair and his bodyguards when they open the box.
Gossipy Hens: Dice's frequent contacts Cynthia, Janis, and Vivian.
Heroic Sacrifice: Michal and Ian both give their lives so that Clair can escape from his own mob (which has been taken over by Noriega), leaving Clair with their personal trinkets.
Heroic BSOD: Clair has one of these when he temporarily loses control of Vita Company to Noriega. Subverted when Clair tries to force one on Daisuke with help from a drug. Turns out Daisuke's personality doesn't tend toward angst, leaving him with not enough regrets to go catatonic. He recovers from the drug sooner than Clair expects.
Kia's abusive Jerkass of a father faces no punishment for the way he treated Kia or his mother, although this may be the point, as real-world celebrities rarely get held accountable for the things they do no matter how bad they are.
Kick the Dog: Clair does this. A lot. Shin too, toward the end
Mad Bomber: Clair. Also, another guy, who appears in one episode.
Man Behind the Man: Noriega was set up as the Big Bad fairly early on, but is later revealed to be working for the Shop Echigo, who is then revealed to be Shun Aurora, the real Serge Echigo having been dead for years prior.
Mind Rape: Someone from the Magnagalia Prison comes after Boma to brainwash him and take him back.
Mood Whiplash: Not as extreme as in some cases, but comes up every so often because of the contrast between the show's idealistic and hopeful outlook on life and its grim subject matter.
Old Master: Shogun is an ex mob boss and managed to vanish into thin air when Shun tried to shoot him. Mauro is this, being an expert marksman.
Nightmare Fuel Station Attendant: Teto. This Uncanny Valley cute robot kid is programmed to ask "Is this alright?" when following orders, but it sounds creepy. (Just ask Clair!) Teto's singing also causes flashbacks, and he takes a security guard's face in a quest to destroy J!
Nuclear Weapons Taboo: It's unknown what the Celestials' power source is, but it sounds an awful lot like nuclear power the way it's described.
Space Amish: The Siberbians, who live quite contentedly outside of Judoh in a self-sufficient community without any of Judoh's modern (or post-modern) conveniences.
On the other hand, they can be seriously anti-social jerkasses that would make Ayn Rand roll her eyes. In Siberbia, self-sufficient means self-sufficient — if you need a hand to carry a heavy load, or not fall off a cliff to your death, you're seen as weak. They have a Freudian Excusenote trauma from the Celestials shutting down the city their ancestors came from, and from having to deal with survivalist wannabes begging for help at all hours, and they've developed I Was Just Passing Through into an art form.
Tsundere: Cynthia, Janis, and Vivian (Daisuke's fangirls). But most prominently, Kyoko, especially in the manga, towards Daisuke and vice versa. After Kyoko tries to rescue Daisuke, the two start to defrost to the point they don't snip at each other, and in the end, Kyoko tells Daisuke that he'd better come back if he's serious about her; she'll only wait so long.
Trauma Conga Line: Happens to Clair midway through the series, where he has to deal with being framed for an assassination attempt which he did not commit, having Ian die trying to clear his name, discovering that Mauro sold Company Vita to Noriega to protect him, having Mitchal sacrifice his life to save him, having to go into hiding in the slums where Giovanni used to live and be around people he'd been raised to believe were disposable garbage, and then we learn that people are after his left eye because his bank safe opens via a retina scanning device. No wonder the poor kid spends so many of the ensuing episodes in an Angst Coma!
Used to Be a Sweet Kid: Both Clair and Shun are portrayed as way more innocent in flashbacks than they are in the series proper. Shun is a special case, since he got the way he is in the series owing to trauma he suffered by protecting Daisuke from the explosion that killed their father.
Weapon of Choice: Boma with his sword and Daisuke with his pistol. Clair Leonelli is also very fond of hand grenades, affectionately referring to them as Fireworks.
Wire Dilemma: Subverted in episode 3; Bomb. Daisuke finds a bomb, opens the panel, and finds two wires. He cuts the red wire first, which cuts the timer down from 13 minutes, to one. He then cuts the other wire, which turns it to 13 seconds. J shows up and saves the day.
A Wizard Did It: Every so often, strange folk called the Celestials visit Judoh and magic away the pollution.
The Worf Barrage: The Red Cap bullets. They're very impressive, but only significantly lead to the defeat of an enemy twice, and the second time is arguable.
