Directory: CharactersDr. Slump

Dr. Mashirito (Dr.ドクターマシリト Dokutā Mashirito) is an evil scientist who is Senbei Norimaki's rival and the creator of Obotchaman. He is considered to be the main and most recurring antagonist of the Dr. Slump series.

Dr. Mashirito's name is an anagram of Kazuhiko Torishima's last name and is based on him.[1] According to Torishima in an interview with Forbes, the idea came from him viewing Mashirito's original design as being not intimidating enough and asking Akira Toriyama to think of the one person he hated the most; Toriyama appropriately took inspiration from the strict Torishima, much to the latter's exasperation.


Dr. Mashirito is a fairly short man with curly black hair (which is dark blue in the original Dr. Slump anime) worn in an afro style, narrow, beady eyes, a long nose, and what appears to be a chipped or missing tooth on the top-left corner of his mouth. He wears a white lab coat, a pink sweater, a red tie, and teal pants. Strangely, he also wears high heeled boots, presumably to make himself look taller and more menacing. After rebuilding himself as a cyborg, he wears two metal plates; one on his left eye, and the other on his chin, and his left hand is replaced with a metal crab-like claw. After being killed by Obotchaman's N'cha Cannon, Mashirito takes on the form of a ghost with a triangular paper burial cap, a white burial kimono, and a tail replacing his legs. In Dragon Ball Super, he maintains his appearance as a ghost, although his skin color has changed from flesh to blue-gray, and his kimono is replaced by the lab coat, sweater, and tie he wore when he was alive.


Dr. Mashirito is a brilliant, but ambitious, evil-minded, megalomaniacal, and unscrupulous evil genius who possesses intelligence equal, if not superior, to Senbei's. He is also very arrogant, egoistic, and hubristic, thinking highly of himself, and is not above transforming himself into a cyborg in order to accomplish his goals; he even claims that he would still conquer the world beyond the grave. He is also quite perverted, much like Senbei. In many of his appearances, he frequently says "rejected", a reference to earlier gags in the series featuring his namesake, Kazuhiko Torishima, frequently rejecting Toriyama's ideas and scripts.




Dr. Mashirito before he becomes a cyborg

Dr. Mashirito is a self-proclaimed genius scientist with aspirations of world domination. At an unknown point in the past, he became acquainted with Senbei Norimaki, and left an impression of being an "uber-pervert". At some point, he gives birth to a son called Dr. Mashirito Jr., who later goes on to create an evil counterpart of Arale Norimaki called Abale in the one-shot anime short Dr. Mashirito Abale-chan.

Dr. Slump[]

Dr. Mashirito starts his conquest for world domination when he builds his robotic suit Caramel Man 001. When he asks a magic mirror who the strongest robot in the world is, the mirror shows Arale Norimaki, making his goal to defeat her with Caramel Man 001. Mashirito travels with Caramel Man 001 to Penguin Village in order to fight with Arale. When he is easily overpowered, Mashirito gets out of Caramel Man 001 and takes Arale's glasses off to make her not see straight in hopes of beating her. He accidentally bumps into Senbei Norimaki while returning to his robotic suit, which takes him time, and then he finds out that Gatchan ate Caramel Man 001 before he could get back into it to defeat Arale.

He makes a cameo in "The Biggest Bye'cha of All", and has the role of one of Cinderella's half-sisters in "Cinderella, the Musical". Dr. Mashirito is a contestant in the race organized in the "Penguin Gran Prix" chapters, using Caramel Man 002 as his vehicle.

After several more failed attempts to destroy Arale (including creating Caramel Man 004, who turned against him, befriending Arale and renaming himself Obotchaman), Mashirito begins to convert himself into a Cyborg, replacing more and more of his body with mechanical parts in an attempt to create


Dr. Mashirito as a ghost, and with his inventions, in the final Dr. Slump episode

Dr. Mashirito dies in the final round of the "Who's the Strongest in the World?" tournament when Obotchaman steps into the fight disguised as Arale and uses an N'cha Cannon on him, reducing his full cyborg Caramel Man 009 body to nothing but a bolt. He makes an appearance as a ghost at the end of the series, witnessing the launching of Senbei's rocket and swearing that he will still take over the world one day.

Dragon Ball Super[]

"Future" Trunks Saga[]

Mashirito returns from Hell as a ghost and attacks the "World Invention Award" ceremony out of anger for not being invited. By using Playtime X to manipulate Arale and Gatchan's childish desire to play with others, he is able to get them on his side. Trunks and Mr. Satan then attempt to fight Mashirito, but to no avail, as their attacks are unable to connect with Mashirito's ghostly body. Bulma uses the Reality Machine to create delicious food, summoning Beerus to Earth. Unaware of Beerus's power and identity, Mashirito insults Beerus and promptly gets destroyed as a result.[2]

The Brief Return of Dr. Slump[]


Dr. Mashirito in Brief Return

Dr. Mashirito returns in the sequel manga The Brief Return of Dr. Slump, inexplicably returned to life after his demise in the original manga and appears without his cybernetic upgrades. He initially appears disguising himself as Akira Toriyama and hosting an event known as the "Penguin Village Game Grand Prix" but reveals himself and releases Caramel Man 010 to attack Penguin Village after Arale wins the event. Mashirito goes on to antagonize Arale and Senbei several more times throughout the rest of the manga.

In a chapter parodying the Super Sentai franchise, Mashirito appears as the main villain, facing off against Arale's team of "Ararangers". After his mech is destroyed by Arale, Mashirito perishes, and ends up in the Other World, where he is sentenced to Hell by King Yemma. As a result, Mashirito angrily demands that someone brings him back to life using the Dragon Balls. However, Mashirito appears alive and well throughout the rest of the manga, as the chapter in question takes place outside of the series' continuity.

This presumably takes place during the time period in which Dragon Ball GT occurs, given that Goku, Pan, and Trunks make an appearance in a different chapter in the Grand Tour Spaceship, though despite this, it appears that he and the other residents of Penguin Village have barely aged.

Later, he becomes robotic like in the original manga and anime, however, his left hand, which was replaced with a metal crab-like claw in the original version, appears no different from an ordinary hand in the remake. He also has the number "8" painted onto his chin, stating he is Caramel Man 008. In episode 60, Dr. Mashirito steals all the Dragon Balls from Goku using one of his robots. General Blue and Murasaki then end up stopping him and taking the balls for themselves.

Video Game Appearances[]


Dr. Mashirito in Hero Retsuden

In Hero Retsuden, Dr. Mashirito is an antagonist.


Dr. Mashirito and Piccolo fusing in Jump Super Stars

In Jump Super Stars, Mashirito is a playable character and the main antagonist. His main form of attack is by piloting Caramel Man 001, though in his idle animations he appears outsides of the mech. He can fuse with Piccolo for a tag attack, the resulting character using a yelling attack. This fusion is a reference to the fact that both characters were based on Akira Toriyama's first editor, Kazuhiko Torishima.

In Jump Ultimate Stars, Dr. Mashirito plans to take control of the Jump universe. A future version of him serves as the final boss and main antagonist, piloting a robot known as Caramel Man J.

Voice Actors[]



  • In Dr. Slump, it is mentioned that Kazuhiko Torishima had to change his hairstyle due to being repeatedly made fun of and called "Dr. Mashirito" after the character was introduced. Torishima supposedly made Akira Toriyama swear to never draw his new haircut in the manga, which is why Torishima is depicted with a cloth wrapped around his head in most of his future cameos afterwards.
  • Mashirito is the first and currently the only character in the Dragon Ball franchise to die while he's already dead onscreen. This means his actual soul was destroyed, and that he was erased from existence itself.
  • Mashirito is the only Dr. Slump character and villain to have been wholly erased from existence in the Dragon Ball series, due to his ghost being destroyed by Beerus.
  • In the Funimation dub of Dragon Ball Super, Dr. Mashirito refers to Hell as the Home for Infinite Losers, which is what the acronym HFIL literally stands for. This is presumably a reference to the early edited dubs of Dragon Ball Z, as Hell is not censored in the Dragon Ball Super Funimation dub which aired on the Toonami block of Cartoon Network's Adult Swim.
  • Mashirito has an unnamed wife[3] that has never been seen. He had his son, Dr. Mashirito Jr., with her.
