Robot Kid

Go To

Senbei: That is because you are a robot, you don't change.
Arale: I wanna wanna wanna grow big!

A robot built to look and/or act like a child. A good number of these are boys, but there are many that are girls.

Possibly made as part of a Robo Family, or to be taken care of as a child of a human family (possibly as a Replacement Goldfish for a lost child of the creator or if the creator can't have biological children). When the kid's mechanic serves as a mentor and emotional caretaker, she's a Motherly Scientist (Fatherly Scientist if he's a man).

May fall into Really 700 Years Old or Older Than They Look unless the robot was very recently built. If they were built very recently, they might actually be Younger Than They Look instead. In either case, it's common for the robot to feel that Not Growing Up Sucks.note  Most Astro Clones are Robot Kids.

    Anime & Manga 
  • Astro Boy:
    • Astro. He's one of the Replacement Goldfish examples, but he also has combat abilities. Astro also has a younger sister and an often Adapted Out brother.
    • One episode of the 1980s reboot involved a child robot being voted as president of a country.

  • The main character of the short anime movie Hotori - Tada Saiwai o Koinegau is a little robot boy.
  • Reg from Made in Abyss looks no older than twelve, and he is quite naïve.
  • Frankenrobo from Anpanman. Baikinman made him as a weapon against Anpanman, but he never became evil like Baikinman wanted, and Baikinman now tries to avoid him in any way he can, thanks to the fact that Frankenrobo now thinks of Baikinman as his dad, which leads him to hugging him, thus harming him thanks to Frankenrobo's electric touch. Baikinman later would attempt to create three other robots that started out evil...but thanks to Frankenrobo touching them and restarting them with his electricity when they were being repaired, they became as childish and friendly as their "big brother".
  • The title character of Cybot Robotchi.
  • Teto from Heat Guy J. He is designed as a small child, programmed to obey any command without question, and ask if whatever he's done is to the human commander's satisfaction. He was built illegally by an old man who says he was lonely, but then revealed that he is sadistic and cruel; basically, he built Teto as his personal punching bag. Teto is "kidnapped" by Clair, who wants to use him to lure and destroy J. His programming unnerves Clair, because of his training by his abusive father.

  • Vicki from Small Wonder is a robot girl built by an engineer, who proceeds to pass her off as his daughter.
  • A villainous example occurs in Taiyou Sentai Sun Vulcan, where Black Magma builds a robot version of a man's dead daughter.

He was unable to build Simon a complete body right away as most of the parts were stolen from his workplace, Concorde Robotics, while the remainder were salvaged from an earlier, unfinished robot body. Gideon treats the robot Simon as if he were his real son, which his niece Zoe finds creepy and off-putting.

    Tabletop Games 
  • Kid Robot is a member of the Emerald City Sentinels in Mutants & Masterminds. Originally the AI to control a Kintetic Deflector, the Motherly Scientist who created him agreed to give him a humanoid body when she realised he was self-aware, and is now his legal guardian.

    Visual Novels 


    Western Animation 
  • Futurama:
    • Tinny Tim, the little robot orphan with the British accent.
    • Also Bender's son in the DVD movie Beast With a Billion Backs.
    • Bender himself reverts to a kid robot in an episode where the crew starts rapidly aging backwards (even though a flashback showed him being assembled in his present form in a previous episode...).
    • Ben from "The Bots and Bees", who eventually goes off to bending school at the end of the episode upon reaching the robot version of young adulthood.
  • The Adventures of Jimmy Neutron, Boy Genius has Brobot, created to be a younger brother rather than a son to his creator.
  • Jenny of My Life as a Teenage Robot, though as the name would imply she's a teenager rather than a young child. She also has "siblings"—earlier prototypes made by her "mother"—that are based on younger kids, however. There is also the fact that while Jenny is designed to look like a teenager, she is chronologically 5 years old — a fact that forced her to transfer to kindergarten in one episode.
  • The title character of the cartoon Robotboy is a doll-like robot with the mind of an 11 year old Japanese exchange student. There's also Robotgirl and Protoboy, who fit this trope as well. They all drop the childlike appearance whenever they engage their larger and more threatening super modes, however.
  • Transformers:
    • Wheelie, the young Autobot they find fending for himself with a slingshot on Quintessa in The Transformers: The Movie. In subsequent episodes of the cartoon he would be paired with Daniel to make a Cute Kid and Robot pair.
    • Beast Wars introduced the concept of "protoforms", which are apparently what passes for an infant phase among Transformers. They look like a mannequin made of flowing, silvery metal and become fully "grown" after getting the proper coding.
    • Sari Sumdac for the first two seasons of Transformers: Animated is the Robot Girl variant. It's harder to tell because those seasons the 'bot in question is in its alt-mode, a human.
  • Robot Jones of Whatever Happened to... Robot Jones? He originally had a robot voice but this was replaced with a boy's voice later.
  • Big Guy and Rusty the Boy Robot. Rusty was not built as a family robot, though, unless all family robots fire energy beams from their hands and can fly around. Rusty, originally meant to replace the outdated Big Guy (who is actually a Humongous Mecha with a pilot inside, despite what the public believes). However, Rusty's childish demeanor and inexperience relegate him to the post of a sidekick, while the Big Guy still takes care of the big problems. Rusty even has a mother in his inventor, Dr. Slate.
  • Rock and Roll in Mega Man (Ruby-Spears) are teenagers, in contrast to their younger game versions.
  • Bobert in The Amazing World of Gumball, a robot from the Bobert Store who attends Elmore Junior High along with all the human-like objects and animals. Why he goes to school is not explained or questioned.
  • Adventures of Sonic the Hedgehog: Robotnik Junior from his namesake episode was created by Dr. Robotnik to be his son and help him get rid of Sonic. However, as a result of treating Junior better than his previous creations, Scratch and Grounder, the latter two try to get rid of Junior, resulting in Sonic having to save Junior, which itself leads to Junior turning against Robotnik.
  • DuckTales (2017): B.O.Y.D., created by tech billionaire Mark Beaks to get himself into a rich kid's birthday party. By the end of the episode, he's reprogrammed to be said rich kid's adoptive brother.
