Dr. Mashirito was 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 Kazuhiko Torishima's last name reversed, and is based on him. 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 an evil genius whose intelligence is equal, if not superior, to Senbei's. 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 is slowly converting into a cyborg over time. He has a son called Dr. Mashirito Jr., who creates an evil counterpart of Arale Norimaki called Abale-chan in the one-shot Dr. Mashirito and Abale-chan.
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". He 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.
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.
