Obotchaman (オボッチャマン) is an android built by Dr. Mashirito using the plans for Arale Norimaki, but male. Despite being introduced later in the series, he becomes quickly one of the major characters in Dr. Slump and a love interest to the heroine.


Obotchaman takes the form of a thirteen-year-old boy and is roughly the same height as Arale. He has large eyes with blue irises and no visible pupils and short black hair with two conical points resembling a devil's horns. He wears a pair of thin round-framed glasses, a white polo shirt with a red necktie, light blue shorts with braces, yellow gloves, and black loafers.


Obotchaman is in many ways the opposite of Arale. He's always very dutiful, well-behaved, and polite to everyone, in contrast to Arale's wild, fun loving and energetic attitude. He's deeply in love with Arale because he finds her cute and charming, and as a result, he can become sentimental and even a bit cheesy, however he's too shy to express his feelings around her. Although he's not dense and clueless like Arale, he can be naive and awkward in some situations.

Obotchaman meeting Arale

Initially dubbed "Caramelman #4", Dr. Mashirito tells him that Arale wants to take over the world and he has to destroy her. He tries repetitively to destroy her, but he can not because she is super cute to him and she does not seem evil.

Later, he figures Senbei Norimaki created her, so he must be evil and goes for him. At that exact time Dr. Mashirito disguises himself as Senbei. So Obotchaman hits Dr. Mashirito and Dr. Mashirito abandons Obotchaman. He later starts attending Arale's school and becomes part of Arale's group of friends as well as a love interest for Arale herself. The house where Obotchaman lives for most of the series was originally Suppaman's house.

Who's the Strongest in the World!!

In the final round of the "Who's the Strongest in the World?" tournament, Obotchaman put on a wig similar to Arale's hair and pretends to be her. He steps into the fight while Dr. Mashirito is laughing with victory. Mashirito is surprised to "Arale" again. Obotchaman kills Dr. Mashirito with a N'cha Cannon, reducing his full cyborg Caramel Man 009 body to nothing but a bolt.

Dragon Ball series


Obotchaman being fawned over by General Blue

Obotchaman is first seen in Dragon Ball when school let the kids out for spring break. At Coffee Pot, he is seen talking to Akane about how he was going to get a part-time job to feed his cats over spring break. When General Blue showed up in Penguin Village, Obotchaman fixed his car that was stolen from Suppaman. Obotchaman happened to be Blue's "type", but the FUNimation Dub changed it to Blue believing that Obotchaman was his long lost brother Samuel, possibly to avoid implications of pedophilia and homosexuality.

He briefly appears with his cats in the beginning segment of the 69th episode of Dragon Ball Super.

Obotchaman remake

Obotchaman in the remake

In the 1997 remake, Obotchaman looks pretty much the same like his original self, but his overalls straps are yellow instead of blue, his glasses are thicker and his gloves are orange.



  • Arale: Obotchaman is in love with Arale, and as the series progresses it becomes more apparent. Arale, meanwhile, doesn't seem to be aware of his crush on her but she adores Obotchaman as a friend. On occasion, Arale admits that Obotchaman is the guy she likes the most implying that she returns his affection deep down but she is still too childish and naive to understand the concept of love and romantic feelings. In the future, they are shown to be together and have a robot child, built by Senbei.


  • Tsukutsun Tsun: In Heart Pounding Tonight Arale invites Tsukutsun to stay overnight at Obotchaman's house with them, causing Obotchaman's jealousy. However this is resolved when Tsukutsun tells Obotchaman that he's not romantically interested in Arale and he likes another girl (Akane). It's also Tskutsun who helps Obotchaman to enter school. Because of Tsukutsun's feelings for Akane, he seems to understand how Obotchaman feels, and they seem to share those feelings with Taro as shown in Donbe's Mischievous Matchmaking. In the Dr. Slump (Remake) Tsukutsun occasionally gives emotional support to Obotchaman when it comes to his relationship with Arale.
  • Taro Soramame: Taro appears to be good friends with Obotchaman, due to Taro's feelings for Tsururin similar to Obotchaman's crush on Arale. They usually get along also with Tsukutsun, as shown in Donbei's Mischievous Matchmaking. There are times where Taro can provide some tips to Obotchaman when it comes to Arale.
  • Peasuke Soramame: They generally have little interaction but seem to be good friends


  • Senbei Norimaki: At the beginning Obotchaman sees Senbei as an enemy and thinks he's an evil genius who created Arale to take over the world, but he quickly realizes the only evil one is his creator, not Arale's creator. Later on, he becomes closer to Arale's family, especially Senbei who knows about Obotchaman's robotic nature and is also the one who provides the robot vitamin A for him, the energy drink that both Obotchaman and Arale need.

Rivals or Enemies

  • Dr. Mashirito: At the beginning Obotchaman shows great respect for Dr. Mashirito, thinking he is a benevolent scientist who loves justice and wants to keep the world safe, so he's very obedient and docile towards his creator, and feels very sad after being abandoned by him. When he learns the truth about him (that he's actually an evil scientist who aspires to dominate the world and was lying to him all the time), Obotchaman shows great disappointment, becoming ready to fight against him, and as the story progresses you can see Obotchaman starting to develop hatred towards Dr. Mashirito. The last straw was in the final round of "Who's the Strongest in the World?" when Dr. Mashirito steals Arale's powers leaving her unconscious and causing an angry Obotchaman to react and kill his creator for good.

Video game appearances

Obotchaman appears as a support character in Dragon Ball 3: Gokuden and Jump Ultimate Stars, and as a playable character in Dragon Ball Z: Dragon Battlers and Dragon Ball Z : Dokkan Battle. He also appears in Dragon Ball Z: W Bakuretsu Impact and Dr. Slump: Arale-Chan.

Voice actors

  • 1980's Series - Mitsuko Horie
  • 1997 Series - Motoko Kumai
  • 1980's Series and 1997 Series (Latin Dub): Patricia Acevedo
  • Dragon Ball (The most known latin dub): Patricia Acevedo (With a girly voice tone)


  • Obotchaman's hair is based on Astro Boy's hair. Obotchaman's hair is probably like this because Akira Toriyama admires Osamu Tezuka's Astro Boy.
  • In one episode, when Tsukutsun Tsun turns into a tiger, he touches Obotchaman to turn back into a human. It is rather strange, due to the fact Obotchaman is an android, not an actual human boy
  • He has similarities with Gohan and Chi-Chi of Dragon Ball. In personality he's similar to Gohan as a kid, plus he is also very smart. Like Chi-Chi, he is in love with the protagonist and dreams of marrying and having happy life with Arale since when they were children, just like Chi-Chi with Goku.
  • It's curious that Dr. Mashirito created a good-hearted robot instead of a evil one like the others, although this may be possible because unlike the other Caramel Men, Obotchaman was designed with the same plans of Arale, which means possessing her same mind and heart.
