Arale Norimaki (則巻アラレ Norimaki Arare) is an android built by Senbei Norimaki, known for her naiveté, energetic personality, superhuman strength, and lack of common sense. Being the world's first perfect android, her only physical flaw is that she is nearsighted and needs to wear glasses. Senbei's mission is to convince the other citizens of Penguin Village that Arale is a human girl, which they appear to believe in, despite taking notice of her numerous displays of superhuman athletic capability.
Creation and concept
Akira Toriyama was told to put in a robot as the co-lead by his editor Kazuhiko Torishima when he mentioned that he wanted to make a manga about a doctor. Initially, Toriyama planned on making the robot big but decided that it would end up being too big to fit in the panels and decided to make it small. Torishima didn't like the idea, so Toriyama created the robot girl Arale since Torishima liked girls.
Arale has the appearance of a little girl with purple hair and wears glasses. Over the years of the series run, Toriyama tended to end up drawing Arale shorter and making her look a lot younger than her appearance at the beginning of the series.
During the reboot, she was slightly redesigned, given brown hair and hazel eyes.
Arale has the personality of a goofy naïve child, despite being intelligent enough to do advanced mathematical equations. She has a somewhat kind personality, by saving her father or neighbors by using her power. She enjoys many popular Japanese Superhero shows such as Astro Boy as well as Giant Monster movies. Her favorite hobby is poking poop with a stick and a weakness of hers is that she cannot resist the urge to poke it.
She is optimistic, friendly, bubbly, caring, somewhat mischievous, an animal sympathizer, funny, clueless, lovely, playful, is able to make new friends quickly, and has a very short attention span. She also has a motherly side, cares a lot about her friends and family and is always ready to help.
A common gag is that Arale, having been designed as a child, complains about not having a "big enough chest," a desire which Senbei declines to fulfill. Her disappointment in this may allude to Arale's inheritance of some of the perversions of her maker. However, it should be noted that Arale has a Pure Heart as she can ride Goku's Flying Nimbus indicating any perversion she may possess is mild at best.
She also tends to lift her shirt with no regard; doing so on one occasion simply to gesture as she asks Senbei if she can launch rockets from her chest.
The Birth of Arale
Arale Norimaki was created in the laboratory located in the house of Senbei Norimaki. When she was first brought out into the outside world around the town of Penguin Village, she was introduced to Aoi, who was the manager of a cafe called the Coffee Pot. There, Arale was given the identity of being Senbei's younger sister to hide the fact that she was an android.
The next day, Arale enrolled into Penguin Village Middle School to fit in with the other kids after meeting the Headmaster. Her teacher was Midori Yamabuki, who was Senbei's dream girl. In class, she was sat next to Akane Kimidori, the rebellious younger sister of Aoi. Arale shocked everybody at the school on her first day with her intelligence during class and strength during P.E. At the end of the day, she followed Akane who was meeting up with Taro Soramame and his younger brother Peasuke. Not knowing Arale's power, Taro tries to intimidate Arale by punching a soda can, but she easily destroys a wire pole in front of them making them scared and gain respect for Arale as their friend.
Arale became popular enough at Penguin Village Middle School to the point that every club in the school wanted her, but she ended up being too good for all of them. She eventually joined Akane's club, the Sukeban Deka Fan Club.
After Senbei finishes working on a time machine named Mr. Time, he shows it to Arale who accidentally gets transported through time. After spending some time in the past, she transports back to the present, proving Mr. Time to be a success.
After the Time Slipper was successfully tested, Arale goes on a journey with Senbei and Peasuke to the prehistoric ages to capture a dinosaur. While they're there, Peasuke's prehistoric ancestor gives them a mysterious egg in exchange for Senbei's lighter. When they return to the present the egg hatched and it turned out to be a strange baby with wings instead of a dinosaur.
Arale named the baby Gadzilla, Gatchan for short, after convincing Senbei to keep it. The next day, Arale and Senbei decided to find out how they were going to deal with raising Gatchan and Arale found out that Gatchan eats metal (among other things). When Arale threw Gatchan really high on accident while playing with it, it fell to the ground revealing that Gatchan can survive that. Later that night in the bath, Arale and Senbei discover that Gatchan had wings.
Arale on the Loose
Sometime after Arale started 8th grade, she came across a bank robber while she was out playing with Gatchan who was running away from the Police when he accidentally robbed the police station instead of the bank. The bank robber thought Arale and Gatchan were just innocent kids and decided to take them as hostages and hide in an abandoned hut. While there Arale tries to play Ultraman with the robber and then accidentally shoots herself in the face with his gun frightening him thinking she killed herself but didn't actually affect her and instead only broke her glasses. Instead, the robber chose to distract Arale by having her blindfolded and try to find him and hit him with a stick like a pinata which she ended up destroying the entire hut with the stick trying to find him. The robber tried to threaten Arale afterward by holding his gun to Gatchan but when Gatchan ate it, he ran away scared trying to find the police as he would prefer to be arrested then dealing with them.
Four weeks later, while studying with Peasuke and Akane at the Soramame Barber Shop, the bank robber returned and tried to take Senbei and Kurikinton as hostages after suffering humiliation from his last appearance to prove he is not a joke. When the police arrive, the kids come into the front area to see what is going on and the bank robber sees that Arale and Gatchan is among the group and decides to run out and turn himself into them but Gyaosu yells at him for being a coward and forces him to go back into the barbershop and continue what he started.
Arale continues to playfully mess around with the bank robber as one of the hostages in the barbershop. Kenta Kuraaku of the Penguin News Network shows up to interview the bank robber but mistakenly ends up interviewing the "hostages" instead until he is amazed when Gatchan eats the microphone which Akane tells him is nothing compared to Arale who can break the Moon with a rock. As night approaches, Kenta continues his news broadcast and focuses on Arale instead who takes a rock and throws it directly at the moon splitting it in half and during the excitement of the crowd watching what Arale is capable of, the robber walks away saying that he will never rob again.
One night when Arale and Gatchan were up really late playing, a giant dice landing in the front yard of the Norimaki house and they went in front to check it out. When they went up to it, it turned into a flypaper trap and they were taken aboard King Nikochan's spaceship by King Nikochan's servant when he was asked to bring some Earthlings. While on the ship, Arale met King Nikochan, the evil king to an alien race called the Nikos. Arale insulted King Nikochan because of his funny looks and did not take anything he said seriously. After they destroyed Mars to try to get her attention, she was too busy messing around with Gatchan. When the Nikos were getting the laser to destroy Earth next, the ship got eaten by Gatchan, which saved the planet.
After the ship was eaten, Arale told them that Senbei can build them a new ship and decided to save the Nikos by having Gatchan fly them to Earth's atmosphere into Penguin Village. On the way to her house, Arale introduced the Nikos to stuff on Earth such as mountains and poop. After she introduced the Nikos to Senbei to have him build them some new transportation, she took them to the Coffee Pot and show her friends the Nikos and all the goofy stuff they do. When they were done and left with the new vehicle Senbei built for them, Arale tells Senbei that they were aliens and that he didn't know and he accidentally built them a car instead of a spaceship, still stranding the Nikos on Earth.
Dr. Mashirito's Ambition
Arale becomes a target for Dr. Mashirito when he finds out that she is the strongest robot around. Mashirito comes to Penguin Village to fight Arale using his robot, Caramel Man 001, but Arale easily beats him. Arale's second encounter with Dr. Mashirito is during the Penguin Village Grand Prix which is held by Tori-Bot. During the race, Arale has no problem even with several distractions setting her back. When it comes down to the last three racers which are her, Senbei and Dr. Mashirito using his Caramel Man 002, the winner is Arale but by technicality, Tori-Bot declares himself the winner.
Shortly after assembling into a team with Sourman, Gatchan and Mr. Pig called the Global Defense Force, Mashirito comes back with his new invention, Caramel Man 003, and his new team, the Mashirito Army, consisting of him, King Nikochan and King Nikochan's Servant. Mashirito's new plan for handling Arale is using a Poop-bot to distract her while he shoots her with a powerful laser, with Gatchan captured in a rubber claw to prevent him from eating the rest of the robot. While Arale is distracted by the Poop-bot, Mr. Pig pops one of Caramel Man 003's tires, causing Arale to pay attention to the fight again, where she headbutts the robot to free Gatchan so he can eat the Robot, leaving Mashirito defeated again.
Mashirito's next conflict with Arale is when he creates his fourth Caramel Man which is known as Obotchaman. Instead of trying to destroy Arale, Obotchaman becomes good and falls in love with her. After a few more conflicts with the various Caramel Man, Arale encounters a fully cyborg Mashirito in a martial arts tournament. Being matched up against him in the final round, Arale battles him but then ends up shutting down in battle and Obotchaman disguised as Arale finishes off Mashirito in the final battle killing him and Arale is declared the champion.
Red Ribbon Army Saga
Main article: General Blue Saga
When spring break starts for Arale and the other students of Penguin Village High School, Arale and the Gatchans witness the sky chase between Goku and the Red Ribbon Army member General Blue. Arale ends up meeting Goku when he falls off of the Flying Nimbus in front of her. When Goku calls back his nimbus to go fly over to the wreckage of General Blue's plane, Arale is amazed at his flying cloud and runs after him. At the site of the broken plane, Goku panics as General Blue and his Dragon Balls are nowhere to be found, and he is then surprised when Arale and the Gatchans appear right before him wondering where they train since they are so fast. Goku tries to use the Dragon Radar to find where Blue ran off to with the Dragon Balls but its broken, so Arale tells Goku that she knows a doctor who can fix it. Arale offers to show where Senbei is and proves to be able to ride the Flying Nimbus along with the Gatchans, indicating that they are pure of heart. When General Blue makes his way to the Norimaki household to kill Goku and steal Senbei's plane, Arale ends up briefly held hostage by Blue, with his placing a knife near her neck with the intent to slit it if Goku didn't surrender the Dragon Radar, although Senbei warned him that using a knife to threaten her was a bad idea, which was confirmed when she licked the blade, to Blue's shock. After Goku was disabled by Blue's special ability, Arale saves Goku by launches him into the air with a headbutt, knocking him away to an Egypt-like country. Arale's strength impresses Goku, which makes him admit that she is way stronger than he is and he tells her that she should fight in the World Martial Arts Tournament before leaving.
Arale becomes the mayor of Penguin Village after winning the 2nd Annual Penguin Village Grand Prix. Ten years later in Age 759, she marries Obotchaman and moves in with him and they raise a robot child together that Senbei created. It is confirmed that Arale lives past the age of 73 having no physical changes in Age 805 since she is an android.

Other Dragon Ball stories
- Budokai Tenkaichi 3
The "Dream Match: Goku vs. Arale" story in depicts a world in which Arale challenges Goku to a game of wrestling and is barely defeated by him, with Goku praising her for her power.
Arale can move at Mach 1 while walking, got from Earth to Saturn in a few seconds, and ran around the world many times in a brief amount of time. She can easily lift 100 tons and has enough power to destroy the Earth with a single punch or move the planet from Mars to Venus (which is a distance of at least 141,578,000 miles) with a single stomp. She also survived being crushed between Mars and Earth with little visible damage. Arale is capable of destroying the moon just by throwing a rock at it. She also managed to knock Caramel Man 001 so hard that he flew into the sun in a few seconds and cracked it upon impact. In the crossover episodes of the Dr. Slump remake with Dragon Ball, Arale fights against Goku when he is out of control in his Great Ape form, and she grabs him by the tail and throws him off into an open area. However it is shown in Dr. Slump that she is unable to defeat Caramel Man 007, even with the help of Obotchaman, she is also shown to be unable to defeat the Teapot Genie - who was so powerful it took the likes of an angered Tsukutsun Tsun to defeat.
Arale easily overpowers General Blue in Dragon Ball and defeats Mercenary Tao as well in Dragon Ball: Mystical Adventure. She also was shown to be durable enough to lick the blade of a knife with no visible injury, despite General Blue claiming that it was very sharp.
Later in Dragon Ball Super, Arale proves to be able to easily defeat Vegeta, even after he switched to a gag manga method of fighting and briefly decapitated her. Arale then faces off against Super Saiyan Blue Goku and matches his God Kamehameha with her N'cha Cannon, after which she states that she will use a version of it with 100x the power, to which Goku says he does not think he will be able to stop it. Vegeta himself seems to pin this on Arale being a gag manga character that does not obey the laws of physics. Even so, it seemed Beerus was capable of at least injuring Arale had it not been for some fortunate stomach cramps, though it remains unclear if he would be able to affect her at all.

- Her name is a pun on the Japanese word for a small senbei (あられ, arare), a bite-sized rice cracker. With the family name ("Norimaki Arare"), it refers to a sort of arare wrapped with nori seaweed.
- There is a girl seen in the crowd in "Krillin's Frantic Attack!" that looks a lot like Arale.
- Toriyama reused Arale's character design for the character Lucca in the video game Chrono Trigger.
- In Budokai Tenkaichi 3, before the player engages in battle with Arale in the story mode, Kibito Kai states "I used to be a fan of her!".

- In the 1985 Jackie Chan film My Lucky Stars, there is a scene where Jackie Chan's character wanders around a theme park in disguise wearing a giant Arale costume and even gets into a fight while wearing it.
- During Episode 289 of Dragon Ball Z when Trunks firsts arrives and greets Gohan, a book can be seen with reference to Arale.
- Interestingly, despite time travel being extremely dangerous, Arale's use of the Time Slipper is never mentioned in the Xenoverse series or any other media related to the Time Patrol or Dragon Ball series itself though she would have had to use it at one point as the Gatchans make appearance with Arale appear in the Dragon Ball series. However, it is possible that Arale's antics outside the plot of Dragon Ball series do not apply to the Dragon Ball itself due to Dr. Slump being a gag manga and the Senbei family's use of time travel is mostly harmless as the Time Slipper does not produce alternate timelines.
- The presence of dinosaurs on Earth despite Beerus' assertion in both the Battle of Gods film and Dragon Ball Super that he was responsible for their extinction, may actually be due to Arale's actions in Dr. Slump, that resulted in dinosaurs surviving on Earth. It is unclear if Beerus played any role in the meteorite that Arale pushes up back into space which becomes the Earth's moon. Presumably, Beerus was unaware that the event had been altered and/or may have assumed the meteor took care of it, similar to how he had Frieza destroy Planet Vegeta for him by proxy to eliminate the evil Saiyans, though Frieza spared a few for convenience. It should be noted as a God of Destruction, sending a meteor to impact with a planet would not be out of the realm of possibility for Beerus given his power and position.
