Revolutionary storage devices invented by Dr. Brief that can shrink and contain virtually any object, from motorcycles to entire houses, inside a tiny pill-shaped container.
Capsules, commonly known as Hoi-Poi Capsules or DynoCaps, are among the most transformative inventions in the Dragon Ball world. Created by Dr. Brief, the founder of Capsule Corporation, these small pill-shaped devices use a proprietary technology to compress and store objects of virtually any size. A single capsule can contain anything from a motorcycle to a fully furnished house, released instantly with a click of the top button and a toss.
The technology operates on a principle of matter compression, shrinking objects down to fit within the capsule's compact shell. To deploy an item, the user presses the button on top and throws the capsule; upon impact, the stored object materializes at full size in a puff of smoke. To store an item, the process is reversed, collapsing the object back into capsule form. Each capsule is numbered and color-coded for easy identification.
Capsule technology revolutionized daily life across the entire planet. Transportation, housing, and logistics were all fundamentally altered by the ability to carry enormous objects in a pocket. Capsule Corporation grew into the wealthiest and most influential company on Earth, largely on the strength of this single invention. The technology is so ubiquitous that characters throughout the series casually produce vehicles, shelters, and supplies from capsules at a moment's notice.
Bulma, Dr. Brief's daughter, is the character most frequently seen using capsules throughout the franchise. She introduced Goku to the technology at the very beginning of the original Dragon Ball series and continued to rely on it throughout Dragon Ball Z, Dragon Ball Super, and Dragon Ball GT.
