Spiral Zone

A Merchandise Driven Animated Show from 1987, Spiral Zone has an unusually dark storyline for an 80s action cartoon, complete with nods to the After the End and Zombie Apocalypse genres.

Exty Years From Now (specifically, the far-flung future of 2007), a Mad Scientist-cum-Diabolical Mastermind code-named Overlord covers much of the planet with his Spiral Zone, a dense, fog-like atmosphere which envelops about half the Earth in a spiral pattern. Inside the Zone, any unprotected person becomes a yellow-eyed, disfigured "Zoner" with no free will. Overlord and his enforcers, a motley crew of hardened criminals called the Black Widows, effectively control the minds of millions of Zoners, and they won't stop until they've enslaved the entire world.

The heroes of this bleak future are the Zone Riders, an elite team of "Earth's most powerful soldiers" led by Colonel Dirk Courage. The Zone Riders travel the world, engaging Overlord and the Black Widows in battle, destroying their existing Zone Generators (thus automatically freeing every Zoner in the vicinity), and trying to prevent them from conquering any more territory. However, both sides are waging a desperate war of attrition, with no end in sight.

Most notable nowadays for having a theme song that freakin' kicks.

Tropes:

 * The Ahnold: "Tank" Schmidt of the Zone Riders is an Expy of Arnold Schwarzenegger.
 * All There in the Manual: Overlord's past and Freudian Excuse are only revealed in the Comic Book Adaptation.
 * Animation Bump: By AKOM of all companies as per Word of God (aka Peter DeCelles)
 * Animesque: A borderline example, because the show originated with the Americanized version of a Japanese action figure line.
 * Assimilation Plot: Overlord's high concept behind the Spiral Zone.
 * A Team Firing: Partially justified since the Zoners (the zombies produced by the Zone Generators) are mainly civilians armed with military-grade weapons by the Black Widows, who regard them as Cannon Fodder.
 * Occasionally Zoners who are trained combatants appear, usually displaying competent fighting abilities. Particularly, in "The Best Fighting Men in the World", Overlord zones a Green Berets base, forcing the Zone Riders to fight on his own terms.
 * Applied Phlebotinum: The Zone Riders and the Black Widows use differing methods to protect themselves from the Spiral Zone's Mind Control effect.
 * Bad Future: By now, it's Alternate History.
 * Badass Bookworm/Nerd Action Hero: Benjamin Franklin Davis of the Zone Riders.
 * Catch Phrase: Two: Dirk Courage's "Zone Riders, hit it!" and Overlord's "Black Widows, withdraw!", much to his consternation.
 * Chicago: The home of Max Jones of the Zone Riders, and setting of "Zone with Big Shoulders".
 * Clip Show: Five of them.
 * Cool Bike: The Zone Rider, uniwheel motorcycle used by the Zone Riders.
 * Monowheel Mayhem: The Rimfire Cannon, Dirk Courage's custom ride.
 * Crazy Cultural Comparison: One of the Black Widows is captured but appears to be organizing his fellow inmates. The Zone Riders plan to send someone undercover to learn what he's up to, and Katarina volunteers. Dirk appreciates her enthusiasm but has to gently explain to her that American prisons aren't coed.
 * Darker and Edgier: This show wasn't afraid to be scary. A couple episodes mentioned that some people would rather enter the zone and lose their free will rather than starve or some such.
 * Dragon Lady: The titular gangster in "Lair of the Jade Scorpion".
 * EMP: The Black Widows use one to disable the Zone Riders' equipment in "Back to the Stone Age."
 * Rock Beats Laser: The Zone Riders still save the day, thanks to a group of Australian aborigines who teach them how to use primitive weaponry.
 * Although they ended up doing so with a fresh allotment of working weapons and vehicles.
 * Emperor Scientist: Overlord.
 * Especially Zoidberg: Used in "Small Packages".
 * Expository Theme Tune: The series begins In Medias Res with no proper introduction to the setting, so the entire premise is laid out in the show's theme song; the terrorist attack which resulted in the creation of the titular "Spiral Zone" and led to the events of the cartoon isn't depicted until 54 episodes into the series, shortly before the end.
 * Evil Brit: Duchess Dire.
 * Exty Years From Now
 * Fake Brit: Mona Marshall as Duchess Dire and Frank Welker as Dr. Lawrence.
 * French Jerk: Crook of the Black Widows.
 * Gadgeteer Genius: Dr. Lawrence, the British inventor who provides the Zone Riders' equipment.
 * The Great Politics Mess Up: It's the early 21st century, but the Soviet Union still exists. However, they're working with the Western powers in an Enemy Mine setup to destroy the Spiral Zone.
 * Hot Scientist: Katerina Anastasia of the Zone Riders.
 * Its Personal: Two of the Zone Riders, Max and Tank, have family trapped in the Zone. Also, several episodes feature friends and relatives of both the Zone Riders and the Black Widows getting caught up in the conflict.
 * J Michael Straczynski: He wrote the pilot episode, "Mission Into Evil", then left the show after a dispute with the producers. "Mission Into Evil" was credited to the pseudonym "Fettes Gray".
 * Knife Nut: Razorback of the Black Widows.
 * Land Down Under: The Australian outback is the setting of "Back to the Stone Age", and homeland of Ned Tucker of the Zone Riders.
 * Limited Animation: The majority of the series falls into this. Largely due to poor outsourcing.
 * Lawyer Friendly Cameo: Promotional material strongly implies that the Black Widow "Bandit" is actually notorious terrorist Carlos the Jackal. In 1987, Carlos was believed to be a criminal mastermind; when he was finally arrested in 1994, he turned out to be just a poser.
 * Master of Disguise: Bandit of the Black Widows.
 * Merchandise Driven
 * Mind Control: The entire premise of the series.
 * Multinational Team: Both the Zone Riders and the Black Widows.
 * Never Say Die
 * New York City: The Black Widows' headquarters are in the Chrysler Building.
 * No Ontological Inertia: Once a Zoner is removed from the Spiral Zone, s/he quickly returns to normal with no lasting effects.
 * Non Lethal Warfare: A Justified Trope because the Zone Riders don't want to hurt the victimized Zoners, and the Black Widows need Life Energy to power their Zone Generators.
 * Philadelphia: Setting of "Overlord's Mystery Woman".
 * Power At a Price: The Black Widows' "Widow Maker" device immunizes them from the Spiral Zone's Mind Control effect--at the cost of leaving them hideously disfigured.
 * Product Placement: Besides the obvious Merchandise Driven element, in one episode Tank gives a hospitalized girl a Pound Puppies doll. At the time, both the Spiral Zone and Pound Puppies toy lines were made by Tonka.
 * Quirky Miniboss Squad: While the Black Widows are serious villains, it's amusing to watch them continually betray each other as they curry Overlord's favor.
 * Sixth Ranger: Ned Tucker and Ben Davis for the Zone Riders, Crook and Rawmeat for the Black Widows.
 * Sixty Five Episode Cartoon
 * The Smurfette Principle: The Zone Riders and the Black Widows have one female member each. Naturally, the heroic Zone Rider, Katerina Anastasia, is a Russian hottie (with a science degree to boot) because Beauty Equals Goodness. Meanwhile, evil Black Widow Duchess Dire is grotesquely disfigured by a patch of red chitinous carapace covering half her skull (and sports an ominous "zoner" yellow eye as well).
 * The Squad: The Zone Riders.
 * Twenty Minutes Into the Future: The show still looks like this, even though its setting is now in the recent past.
 * Unobtainium: Neutron-90, the rare material that the Zone Riders' uniforms are made from; it protects the soldiers from the Spiral Zone's Mind Control effect.
 * Villain Protagonist: The show attempts to depict Overlord as a sympathetic villain who only wants to rule the world so he can bring peace and order to it, but he's such a horrible villain that this isn't pulled off very well.
 * Well Intentioned Extremist: Colonel Conrad in "Zone of Darkness".
 * You Can't Make an Omelette: Ned uses this exact phrase in "Oversight".
