Apocalypse Zero, known in Japan as Encouragement of Resolve (覚悟のススメ), is a manga series written and illustrated by Takayuki Yamaguchi. It was serialized in Akita Shoten's Weekly Shōnen Champion from July 1994 to August 1996.

Plot
Kakugo and Harara are brothers trained by their father, Oboro, to slay monsters that have begun roaming the streets of a post-apocalyptic, 21st century Tokyo following a devastatingly, powerful earthquake. To aid them in their quest, Oboro entrusts his two sons with Fortified Armor Shells (強化外骨格), cyborg exoskeletons forged using the souls of deceased warriors by their grandfather, a former scientist of the Imperial Army of Japan during World War II, Shiro Hagakure. However, Harara becomes possessed by a mysterious evil from deep within his armor, mutating his body as well as filling him with a desire to destroy all of mankind to help cleanse the Earth of contamination. Some years later, Kakugo moves to "Reverse Cross High School", located in one of the ruined districts of Tokyo near the castle from which Harara commands their demon army. It's now up to Kakugo to defeat his evil sibling and put a stop to their wicked legions.

Main

 * Kakugo Hagakure (葉隠 覚悟)
 * The main protagonist of the series, owner of the Fortified Armor Shell known as Zero (零(ぜろ)). Unlike Harara, Kakugo stuck to his duty to protect innocent citizens in trouble. This leads to several encounters with a large number of monsters which inhabit the city until finally he comes face-to-face with Harara himself. Kakugo is a stern and humorless, yet compassionate and honorable person, wearing glasses and a white uniform inspired by the regimental uniforms worn by the Imperial Japanese Navy. Kakugo is a master of the Zero Defense Form (零式防衛術) of martial arts and has eight steel balls embedded in his body, which he can absorb into himself to coat his skin in metal or eject from his body to use as weapons. His signature technique is Impact (因果) (lit. "cause and effect"), which is a counter move that redirects all of the energy of an opponent's attack back to them. Zero is mentioned to be the prototype for all other Fortified Armor Shells and is inhabited by the vengeful souls of the 3000 Japanese soldiers sacrificed to create it. The spirits within Zero form a collective consciousness, manifesting as a mass of grimacing skulls, and are able to communicate with Kakugo and advise him in battle.
 * His armored form resembles a red-eyed tokusatsu superhero with a long scarf similar to the Kamen Rider series.
 * Capcom artist Kinu Nishimura had said that Kakugo was the main inspiration for Cyberbots protagonist, Jin Saotome.
 * Kiyotaka Ishimaru from the Danganronpa franchise bears resemblance to Kakugo.

 * Harara Hagakure (葉隠 散)
 * Kakugo's older brother and the main antagonist of the series. Harara possesses the Fortified Armor Shell Kasumi (霞(かすみ)). Bonding with Kasumi caused his body to assume a hermaphroditic form and drove him to insanity, killing his father Oboro in combat and defeating Kakugo. Believing humanity responsible for the death of the environment, he has become determined to destroy all humans with the aid of beings known as Tactical Fiends. Like his brother, Harara has multiple steel balls embedded in his body which he can absorb to coat his body in metal and increase his strength. His signature technique, Spiral (螺旋), draws energy from the Earth into a strike that can force an opponent's internal organs to violently erupt from their body. The Fortified Armor Shell Kasumi has a feminine form and is inhabited by the malicious spirit of Mei Inukai, whose endless hatred for humanity after her infant son was sacrificed during Kasumi's creation drives Harara's desire to exterminate humanity.
 * After Kakugo defeats the Tactical Fiend Eikichi, Harara directly possesses Eikichi's body in an attempt to finally destroy Kakugo. In the ensuing battle, Kakugo manages to emerge victorious over his sibling, leaving Harara in a coma for most of the manga.

Reverse Cross High School

 * Tsumiko Horie (堀江 罪子)
 * A girl who goes to the same high school as Kakugo. Although frequently called unattractive and chubby, Horie is a kind and bold girl who falls in love with Kakugo after witnessing him destroy the city's monsters. She is later kidnapped by Chidokuro and turned into a Tactical Fiend, thus forcing Kakugo to fight against her, until he kisses her, which results in her turning back to her normal self. Series creator, Takayuki Yamaguchi named her after Mitsuko Horie (whom he's a fan of), in fact, her name is actually an anagram for "Mitsuko". Horie herself would later go on to voice Tsumiko in the OVA.

Manga
The Apocalypse Zero manga series was written and illustrated by Takayuki Yamaguchi. It was originally serialized in the Akita Shoten magazine Weekly Shōnen Champion from 1994 to 1996. A total of 11 tankōbon (chapter collections) volumes were published by Akita Shoten. An English translation of the manga was published as a graphic novel in the US by Media Blasters beginning on January 19, 2005. The manga was sold shrink wrapped, presumably due to the large amount of violence. Only six of the original 11 volumes were translated and released, as Media Blasters chose to cease publication of the series in early 2007.

The manga was published in Italy by Dynamic Italia, flipping it in a left-to-right format.

From 2010 to 2014, Yamaguchi wrote Exoskull Zero, a reboot of Apocalypse Zero featuring a similar protagonist in a slightly different plot. It was published in Akita Shoten's Champion Red magazine.

OVA
The Apocalypse Zero anime OVA was co-produced by Victor Entertainment, Tomy and Big West Advertising, it was animated by Ashi Productions and directed by Toshihiro Hirano. It was released in Japan in two volumes from October 23, 1996, to December 18, 1996, on VHS and Laserdisc. The OVA was planned to have ten episodes, but was canceled after the completion of the second episode. The reasons for the OVA's cancellation are currently unknown. The anime was released in Italy in 1999 on VHS, licensed by Dynamic Italia. The US license for Apocalypse Zero was acquired by Media Blasters who created a dubbed English language version of the anime translated by Takashi Sakudo and produced by Bang Zoom! Studios. The two VHS volumes were released from June 20 to August 22, 2000. A DVD release containing both episodes was released on August 28, 2001.

A Region 2 DVD of the series with both episodes was released in Japan by Toshiba in 2003.

Video game
A video game based on Apocalypse Zero was released on the PlayStation on March 21, 1997, exclusively in Japan by Tomy. The game is a standard 3D fighting game allowing the player to go head-to-head against the CPU or against another player. It features seven characters to choose from based on both the anime and manga, and animated cut scenes taken from the OVA.

Reception
Due to the use of gratuitous violence and repulsive imagery, critical reception to Apocalypse Zero in the west has been largely negative. John Oppliger of AnimeNation called the Apocalypse Zero OVA "the most viscerally violent and gruesome anime" he has seen and "arguably the most grotesque anime ever made". Animerica called Apocalypse Zero the "Best Anime Splattervision" in its "Best of the Best" awards. "When a 45-minute video features a scene where someone's face is sucked off, and that's not even the most shocking thing in the video," the magazine proclaimed, "you know you'll be getting your horror-show money's worth."

Despite this, the manga was well received and popular in Japan. Apocalypse Zero managed to be one of the finalists for the 1997 Tezuka Osamu Cultural Prize, losing out to Doraemon by Fujiko Fujio.

Context
The Japanese title is an allusion to An Encouragement of Learning (Gakumon no Susume) from Yukichi Fukuzawa, an important early Japanese advocate during Meiji Restoration.
