And Now For Something Completely Different: In a parody of anime plots that completely go Off the Rails, Inferno Cop quickly goes from hard-boiled supernatural shonen, to kamen fighting, to Slice of Life, to extremely specialized episodes focusing solely on a food item, to racing, to a bizarre out-of-nowhere Gainax Ending that shouldn't involve hardboiled supernatural police. And all of it is funny as shit.
Animesque: Inverted. The series' art style seems to be heavily influenced by American comic books.
Like a Badass out of Hell: Inferno Cop and Mecha Cop accidentally wind up in Hell after becoming Gods (and annoying Yahweh himself). They only find a way out after Inferno Cop's aunt gives them directions.
Cool Shades: Inferno Cop sports these - even when he's wearing goggles.
Cowboy Cop: Inferno Cop, supposedly an undead cop given life to reenact vengeance on his enemies. Subverted for laughs, later on, as it reveals Inferno Cop is a branch of cops somewhere in Japan, and Inferno Cop gets admonished by his boss.
Everything's Better with Dinosaurs: Inferno Cop and Mecha Cop go to the Cretaceous period, where they are assaulted by enormous dinosaurs. Later in the series, during the Rally, one of them drives a dinosaur, and in the finale, they show up for absolutely no reason at all.
Gag Series: Small-budgeted parody of gritty vigilante-fighting-for-justice-in-rotten-towns-shows, and shonen/seinen anime in general.
Gainax Ending: Mocked. The last episodes toss out any "plot" the series had in favor of mashup of Neon Genesis Evangelion and House of M... just as how Neon Genesis Evangelion opted to go for a bizarre apocalypse than continue its series.
Heroic Sacrifice: Hellfire Boy is used as fuel so Inferno Cop can pass Mr. Judge in the American Grand Prix. Unfortunately, it's all in vain; Mr. Judge still wins the race and the prize money.Double Subverted in that Inferno Cop still wins the same amount of money for coming in second, and Hellfire Boy somehow survived getting burnt to death to bang his hot girlfriend in the Distant Finale.
Hot-Blooded: Inferno Cop gets this way during particularly tense moments. Considering he's literally on fire, not a surprise.
Hot Scoop: Ariel Suzuki, Zombie news broadcaster. Later literally becomes hot as Third Destroy Finale explodes everything on Earth.
Hypocritical Humor: Inferno Cop, when dealing with Mecha Cop, says that he relies too much on machines. Inferno Cop then turns into a car and defeats Mecha Cop with ease.
Infant Immortality: Nope. Well, it's okay to kill babies, when they're actually mutant sea monsters working for the local Ancient Conspiracy. Also, a baby head is the first to die in the Episode 8 race.
Larynx Dissonance: Everyone is voiced by a small group of men. Even the crying, high-pitched damsels and babies (that turn into sea monsters).
Meaningful Name: Inferno Cop is a cop out of hell. Mister Judge is a judge. Mecha Cop is a robot.
Medium Blending: Fire, explosions and a desk in the hospital are all film or photos.
Misplaced Wildlife: The dinosaurs from Episode Four show up in the ending... which is in the year 2085, in the middle of a city going an apocalypse. For some reason.
Nebulous Evil Organisation: Southern Cross, whose members are all cloaked in capes with hoodies, speak in ominous phrasings, mark their people with cross-shaped scars and call themselves "priests". Their current goal is unknown (other than to end Inferno Cop). Parodied when it's retconned so that their sole purpose is to make sure Inferno Cop doesn't become everyone and vice versa.
Ninja Pirate Zombie Robot: Inferno Cop - cyborg undead skeleton rogue policeman who can turn into a time traveling flaming car.
Only Six Faces: The standard male model has appeared as a Southern Cross thug, a judge, a doctor, some zombies, a mummy pharaoh, and a newscaster. And Inferno Cop.
Out of Focus/What Happened to the Mouse?: Southern Cross's role dissipates over the series, to the point they spend several episodes not being brought up, and not until the very end, where they go from "criminal organization" to "ancient conspiracy planning to stop Inferno Cop from turning everyone into Inferno Cop". This is intentional.
Product Placement: Some of the episodes feature ads for the show's merchandise, complete with Japanese "Skip This Ad" button. It doesn't do anything.
Retcon/Re Vision: Mocked when Inferno Cop goes from lone wolf swearing revenge on the local crime syndicate for murdering his family to being a regular cop that's part of a police agency made up of flaming skeleton policemen, also called "Inferno Cop", and Southern Cross goes from crime organization to a cult seeking to stop the transformation of everyone into Inferno Cop. All Played for Laughs.
Rule of Cool: The series runs on this. It has flaming skeletons, a judicial system based on fighting tournaments, zombies, dinosaurs... It's one big parody of anime's usage of this.
Everyone becoming Inferno Cop, including God Himself, in a bid to rid the Earth of humans and be one with each other, to be replaced with perfect specimens is a blend of End of Evangelion and House of M. The Pregnant Woman even turns into The Scarlet Witch.
Surreal Humor: Devolves from parody of hardboiled revenge seinen anime to a surreal mockery and mishmash of every anime trope, ever, such as travelling back into time, meeting your aunt in hell, and fighting mummies in Egypt for no reason at all.
...which roughly translates to "Inferno Glass! Police... from Hell!" Why would one read the first part as "Inferno Glass" can be up for debate, there has been a Twitter convo regarding this between a watcher and... Inferno Cop (actually the official Twitter account for the show). Inferno Cop's response? "Be it 'cop' or 'cup,' both seems the same to me." One might also speculate the lyrics is referring to a book title.
Race Lift: Hellfire Boy goes from being white (pre-reveal) to black, to... white again in the Distant Finale. His mom is also revealed to be Ariel... who is Japanese.
Unexplained Recovery: The nurse at the hospital and Ariel get blown up repeatedly... and always come back, no worse for the wear.
Time Skip: Mocked with Episode Five, where Inferno Cop wakes up from being tossed off a cliff in the year 2085. It has absolutely no bearing on the plot, except for zombies.
Zombie Apocalypse: In the third episode, Inferno Cop awakens from his accident to find out that he's in the year 2083 and there are zombies. For no reason at all. It has no bearing on the plot, except for looking cool.
