Capsule

Capsules (カプセル), also known as Hoi-Poi Capsules and DynoCaps, were created by Dr. Brief of the Capsule Corporation, for the purpose of making objects compact and easy to transport.

Concept & Creation
The concept of the Capsules were first shown in Akira Toriyama's one-shot The Adventures of Tongpoo, which was a precursor to the Dragon Ball series. The Capsules in The Adventures of Tongpoo work differently, they are small pill-like objects that had to be boiled in water to activate.

Overview
Throughout Dragon Ball, numerous objects, from airskis and hovercars, to entire homes, and even organic corpses and house plants, have been seen contained in capsules. The only things that have never been shown in capsules are living sapient organisms.

This single apparent limitation is explored in the Gameboy Advance video game Dragon Ball Z: The Legacy of Goku II, where an optional side-quest has Gohan tracking down a spy in Capsule Corporation, Newman, who was trying to find the formula that Dr. Brief was using to create these capsules for Pod Corporation, one of Capsule Corporation's major competitors. Also in this game, the Janitor of Capsule Corporation explains that he used to work as an inventor and once invented a capsule that went inside another capsule, and that the results were catastrophic. This info is also in its sequel Dragon Ball Z: Buu's Fury, where an Orange Star High School teacher says at the end of his lesson that a capsule should never, ever been put inside another capsule.

Capsules are identified by various classes, one of which is known to be 'M'. Highly experimental prototypes of capsule appear in The Legacy of Goku II, the Golden Capsules that take the user back to the World Map when used in a city or a wasteland (it does not work inside buildings or caves). In the game, Dr. Brief lost 25 of them while he was conducting an atmospheric experiment and asks the Z Fighters to retrieve all of them. Once done, he allows the Z Fighters to keep and use one of the Golden Capsules as many time as they want.

Capsules are distributed by vendors throughout the Earth, although the pricing varies depending on what it contains. It is possible to have an object adapted to turn into a capsule. Capsules are also featured in various Dragon Ball video games as a mean of customizing playable characters. Although capsules are made on Earth by Dr. Brief, in the 2010 Dragon Ball: Plan to Eradicate the Super Saiyans, Dr. Raichi uses one before Dr. Brief would have been born. It could, however, be possible that capsules were created using similar technology on other planet(s).
