Dr. Slump

Dr. Slump (Japanese: Dr. スランプ, Hepburn: Dokutā Suranpu) is a Japanese manga series written and illustrated by Akira Toriyama. It was serialized in Shueisha's anthology magazine Weekly Shōnen Jump from 1980 to 1984, with the chapters collected into 18 tankōbon volumes. The series follows the humorous adventures of the little girl robot Arale Norimaki, her creator Senbei Norimaki, and the other residents of the bizarre Penguin Village.

The manga was adapted into an anime television series by Toei Animation that ran on Fuji TV from 1981 to 1986 for 243 episodes. A remake of the series was created thirteen years after the manga ended, consisting of 74 episodes that were broadcast from 1997 to 1999. The series has also spawned several novels, video games, and eleven animated films.

Dr. Slump launched Toriyama's career. It was awarded the Shogakukan Manga Award for shōnen and shōjo manga in 1981 and has sold over 35 million copies in Japan. The 1997 series was bought over the US by Zuniga/Schreiber Entertainment in 2000, and the company would later buy the rights outside of Japan for it and most of the non-Dragon Ball rights in 2005 and dubbed Arale-chan in 2007 and used the characters for the non-canon Tari and the Meta Runners in 2019.

Plot
Dr. Slump is set in Penguin Village (ペンギン村, Penguin Mura), a place where humans co-exist with all sorts of anthropomorphic animals and other objects. In this village lives Senbei Norimaki, an inventor. In the first chapter, he builds what he hopes will be the world's most perfect little girl robot, named Arale Norimaki. However, she turns out to be in severe need of eyeglasses. She is also very naïve, and in later issues she has adventures such as bringing a huge bear home, having mistaken it for a pet. To Senbei's credit, she does have super-strength. In general, the manga focuses on Arale's misunderstandings of humanity and Senbei's inventions, rivalries, and romantic misadventures. In the middle of the series, a recurring villain named Dr. Mashirito appears as a rival to Senbei.

Humor
Dr. Slump is filled with puns and toilet humor, and parodies of both Japanese and American culture. For example, one of the recurring characters is Suppaman, a short, fat, pompous buffoon who changes into a Superman-like alter-ego by eating a sour-tasting ("suppai" in Japanese) umeboshi. Unlike Superman, Suppaman cannot fly and instead pretends to fly by lying belly down on a skateboard and scooting through the streets. Also, one of the village's policemen wears a Star Wars-style stormtrooper helmet, just as in the American movies. Toriyama himself has been portrayed as a bird (the "tori" in his last name means "bird", hence the name of his production studio Bird Studio), although it has been suggested (by himself even) that he based the design of Senbei on himself. Also, other real-life people make appearances as well, such as Toriyama's editor (Kazuhiko Torishima), assistants, wife, his colleague friends (such as Masakazu Katsura), and others.

Production
With Toriyama, a newcomer to manga, and his editor Kazuhiko Torishima still relatively new at his job as well, the two worked for 18 months with Torishima rejecting all the author's ideas until the first draft of Dr. Slump. One of these rejected works, Ageha-chō Kansatsu Nikki (アゲハ町観察日記), served as a basis for Dr. Slump. Toriyama drew several short marks included in the Dr. Slump tankōbon volumes that supposedly depict actual events in the production of the series, although, as they are often humorous, the level of truthfulness to them is uncertain. In one, he claimed that when he told Torishima that he wanted to make a manga about a doctor, the editor told him to add a robot. Toriyama originally wanted a very large robot, but as it would not fit in the panels, he instead made it small. When Torishima rejected that idea, he made the robot a girl, knowing Torishima would find her "cute". He also stated that Senbei was supposed to be the main character, but his editor told him to make it Arale instead, which Toriyama agrees turned out better. The act of having Senbei and Midori get married came from having nothing else to draw that week, and it happened quickly because he does not like romance. He went on to state that Torishima does enjoy romance, and that the relationships of Arale and Obotchaman, Akane and Tsukutsun, and Taro and Tsururin were all Torishima's ideas.

Toriyama did not expect Dr. Slump to last long, as even before it debuted Torishima was asking him what he would draw for his next series. However, it lasted for roughly five years. When Toriyama began Dr. Slump, he worked at home, where he lived with his parents, and had one assistant who worked one day a week. Toriyama has said several times that he typically would not have any ideas for the story for that week's chapter, but would think up something as soon as Torishima called asking. He thought up each week's story as he drew and sent the rough draft to Torishima at Weekly Shōnen Jump headquarters in Tokyo by air courier from Nagoya Airport. After getting the approval of his editor, he began by drawing the lines that stick out of the frames, then the frames themselves, before using a g-pen to draw clear crisp lines at roughly one page an hour. After he had finished around eight pages, his assistant Hisashi Tanaka (田中久志) (also known as Hiswashi (ひすゎし)) came over, although Toriyama stated he only allowed him to color. For color pages, Toriyama first drew them with permanent ink and used water-soluble color pens, before touching them up with a wet brush. Later in serialization (around volume 13, as stated in volume 18), Takashi Matsuyama (まつやまたかし) became his assistant when Hiswashi started his series, although Hiswashi occasionally still helped out, as did Toriyama's wife when they were close to a deadline.

In 2016, Torishima said that although Dr. Slump was very successful, having debuted at number two in the magazine's reader rankings, Toriyama wanted to stop it after about six months. He explained that because it was a self-contained comedy each week, if something did not work, the author had to change everything. Torishima said that because it was a top-ranking series, would regularly sell a million copies, and had an anime about to begin, Jump and Shueisha would not allow it to end. However, Torishima claimed the magazine's chief editor told him that if they could come up with something more interesting and successful then they could. To have time to discuss new ideas they had to adjust the weekly schedule, finishing a Dr. Slump chapter in five days instead of seven. Toriyama stated that one of the conditions he agreed to that allowed him to end the popular Dr. Slump, was that he started his next series relatively soon after. He began Dragon Ball roughly three months later.

In his own words, Toriyama described the scenery of Dr. Slump as having an "American West Coast" feel. Torishima recalled that when he asked Toriyama why he drew relatively sparse backgrounds, his reply was simply that it was easier that way. However, Toriyama has stated that he was particular about the art, working more hours on it than he would later on Dragon Ball. In an actual chapter of Dr. Slump, where Toriyama and Matsuyama appear, it was revealed that Matsuyama draws most of the backgrounds and houses. Toriyama often used colored paper, a technique fairly common in design, but less-so in the manga. He stated that the tournament-type events, such as the Penguin Village Grand Prix and the Kick the Can contest, were popular with readers and inspired the Tenkaichi Budōkai in Dragon Ball.

Torishima described the Dr. Slump anime as unsuccessful in his opinion because it did not loyally follow the manga. He said this was because it was the first time that the Weekly Shōnen Jump team had to manage an anime based on one of their manga and its creative process, explaining that, if something went wrong, it was too late to change because it was already animated.

Manga
Akira Toriyama's Dr. Slump was originally serialized in Weekly Shōnen Jump from issue No. 5/6 on February 4, 1980, to No. 39 on September 10, 1984. Its 236 individual chapters were collected into 18 tankōbon volumes under the Jump Comics imprint. It was reassembled as a 9-volume aizōban edition in 1990, a 9-volume bunkoban edition in 1995, and a 15-volume kanzenban edition in 2006. Viz Media licensed the series for North America in 2004 and published the first volume on March 3, 2005, with translation done by Alexander O. Smith and some censorship. All 18 original volumes have been released in North America as of May 5, 2009.

After Dr. Slump ended in 1984, its characters returned for an extended cameo in Toriyama's next series Dragon Ball, in which Arale and Son Goku briefly team up to defeat General Blue during the Red Ribbon Army storyline. A Dr. Slump follow-up manga was written by Takao Koyama and illustrated by Katsuyoshi Nakatsuru, with supervision by Toriyama. It was serialized in V Jump from February 21, 1993, to September 1996 under the title The Brief Return of Dr. Slump (ちょっとだけかえってきたDr.スランプ, Chotto Dake Kaettekita Dokutā Suranpu). It was collected into four tankōbon volumes.

To promote the release of the first Dr. Slump - Arale-chan anime DVD box set, Akira Toriyama illustrated a special one-shot colored spin-off manga titled Dr. Mashirito - Abale-chan (Dr.MASHIRITO ABALEちゃん) published in the April 2007 issue of Monthly Shōnen Jump. The story centers around an evil counterpart of Arale created by Dr. Mashirito Jr., named Abale.

Reception
As of 2008, the collected volumes of Dr. Slump had sold over 35 million copies in Japan alone. Only a year after its debut, the series was awarded the 1981 Shogakukan Manga Award for shōnen and shōjo manga. Viz Media's North American release of the first volume of Dr. Slump was nominated for the 2005 Quill Award in the Graphic Novel category. The first anime adaptation of Dr. Slump was also popular, holding the coveted Saturday 6 pm timeslot for five years. With a 36.9% average household rating, it's December 16, 1981 episode is the third most-watched anime since the television rating group Video Research began keeping track on September 26, 1977. In 1982, it was voted the 13th Favorite Anime in Japanese magazine Animage 's fourth annual Anime Grand Prix. In 2001, Animage ranked it number 48 on its list of the Top 100 Anime. TV Asahi released two Top 100 Anime lists in 2005, in the web poll Dr. Slump ranked number 34, while a nationwide poll of multiple age groups named it number 29. The following year, a list created from polling 100 celebrities had it in the 25th position. A running gag in Dr. Slump that utilizes feces has been reported as an inspiration for the Pile of Poo emoji. Ian Jones-Quartey, a former producer of the American animated series Steven Universe and creator of ''OK K.O.! Let's Be Heroes, is a fan of Dragon Ball and Dr. Slump'', and uses Toriyama's vehicle designs as a reference for his own. He also stated that "We're all big Toriyama fans on [Steven Universe], which kind of shows a bit."

Mike Toole of Anime News Network called Dr. Slump "the greatest manga of all time", filled with "parody, gags, and fart jokes that everyone from toddlers to grandparents can enjoy together". Jason Thompson referred to Dr. Slump as the best series Toriyama has created, claiming it is better drawn and more creative than Dragon Ball. He also reports that it is considered "the last non-manufactured hit" by many in the Japanese manga industry, particularly among Weekly Shōnen Jump titles. In their review, Publishers Weekly stated "Toriyama has created his demented sitcom, and his fantastic imagination and comic invention never let up", "The [English] translation is a bit flat, but the uncommonly good storytelling more than makes up for it." Eduardo M. Chavez of Mania Entertainment summarized Dr. Slump as a "quirky slap-stick comedy entirely based in fantasy." He thinks that while Toriyama's usual art style uses "SD" characters, Dr. Slump also shows hints that he can draw realistic. He noted that "little nuances", particularity puns, are lost in translation from Japanese to English and expressed disdain for Viz's censorship, saying it took away from the honesty of the series. Chavez feels that what the characters do never crosses the line into inappropriate; "The jokes might not be wholesome, but they are genuinely funny and harmless"; and went on to say that the series fills the void for "all ages manga" in bookstores and libraries.

Reviewing the first five movies, Carl Kimlinger of Anime News Network summarized Dr. Slump as "random silly adventures [...] delivered with a lot of surreal nonsense humor, only the most basic sense of continuity, and not a whiff of substance or seriousness." He felt that much of the humor comes simply from the visuals; stating that the vintage hand-done art and animation provide a "warmth" and "raises Slump's visuals above" other anime. However, he called the background music "non-descript" and stated that the films are only for viewers who are familiar with the series, as they provide no exposition.
