Main article: List of Doraemon characters
Doraemon has a pocket from which he produces many gadgets, medicines, and tools from the future. The pocket is called yōjigen-pocket (lit. fourth-dimensional pocket). Some of the gadgets (dōgu) are based on real Japanese household devices with fanciful twists, but most are completely science fiction (although some may be based on folklore or religious stories). Thousands of dōgu have been featured in Doraemon. The number of dōgu has been approximated at 4,500. It is this constant variety which makes Doraemon popular even among adult readers/viewers. In the series, the availability of dōgu depends sometimes on the money Doraemon has available, and he often says some dōgu are expensive in the future. The more famous ones include the "bamboo-copter" (very similar to the ones that appears on the older series of Beany and Cecil), a small head accessory that allows flight; the "Anywhere Door", a door that opens up to any place the user wishes; and the "Time Machine". Some of the recurring dōgu appear also in Fujiko F. Fujio's other works such as 21-emon, Kaibutsu-kun, Kiteretsu Daihyakka, Mikio to Mikio or Pāman.
Although he can hear perfectly well, Doraemon has no ears: his robotic ears were eaten by a mouse, giving him a series-long phobia of the creatures.
The only main female character is Shizuka Minamoto (源 静香 Minamoto Shizuka), who serves as a semi-romantic girlfriend of Nobita, but otherwise a supporting, minor character. Nobita's main human friends include Takeshi (sometimes named Jiian in the Indian versions but sometimes his name is mistakenltaken as Takeshi by his mother), a consummate bully and Suneo,a cunning,gloating, spoiled wealthy brat. There are many recurring supporting characters, such as Dekisugi, Nobita's parents, his school teacher, his descendants from the future, and Doraemon's little sister, Dorami.
The stories are formulaic, usually focused on the everyday struggles of fifth grader Nobita, the protagonist of the story. In a typical chapter, Nobita comes home crying about a problem he faces in school and/or the local neighborhood. After hearing him out, Doraemon often offers helpful advice to his problem(s), but that's never enough for Nobita, who is consistently looking for the "quick, easy" way out (which offers insight to the viewers as to why Nobita's life turned out the way it did). Finally, after Nobita's pleading and/or goading, Doraemon produces a futuristic gadget out of his aforementioned pouch to help Nobita fix his problem, enact revenge, or flaunt to his friends.
Unfortunately when in possession of the gadget, Nobita usually gets into deeper trouble than before, despite Doraemon's best intentions and warnings. Sometimes, Nobita's friends (usually Suneo or Gian) steal Doraemon's gadgets and end up misusing them. However, by the end of the story, there is usually retribution to the characters who end up misusing them, and a moral is taught.
