Cloning (分身, Bunshin) is the general ability to split into several identical duplicates to fight as a group.
The cloning technique is encountered quite often in the anime, but the only usage in the original manga is Tien Shinhan's Multi-Form, though it is also used in the official manga adaptation of Dragon Ball: Yo! Son Goku and His Friends Return!!
Piccolo uses this technique to sprout identical sparring partners, notably in Break Wasteland during the Vegeta Saga, once again during the Garlic Jr. Saga, and in the Hyperbolic Time Chamber during the Cell Games Saga. During the battle against the Saiyans Vegeta and Nappa, Piccolo and Krillin use a specific cloning technique called the Tri-Form, splitting themselves into three identical duplicates to fight as a group. This is similar to the Multi-Form technique used by Tien Shinhan, which divides its user into a total of four separate beings. As he possesses the cells of both Tien Shinhan and Piccolo, Perfect Cell was able to divide into four separate beings, though unlike Tien Shinhan's technique, Cell's cloning technique was superior as it did not divide up his power, allowing him to create four clones as strong as Perfect Cell.
One of Lord Slug's henchmen, Medamatcha, creates "clones" that absorb their opponents' ki. Medamatcha's method of cloning is similar to the one used by Cell to produce Cell Juniors. It is similar to a Surinam Toad's way of giving birth; this can be supported by the fact that Medamatcha looks like a frog/toad.
The South Galaxy fighter, Chapuchai, has the ability to create seven clones of himself. Abo and Kado, the main antagonists of Yo! Son Goku and His Friends Return!!, use this technique during their fight against Goten and Trunks.
In Dragon Ball Super, Beerus uses this technique against Goku during their battle. In the Universe 6 Saga, Piccolo uses this technique to create a small army of clones against Frost as a distraction so that he can charge his Special Beam Cannon. Piccolo's clones were as strong as him, however they had the weakness of dissipating if they were hit even once.
In the ''Future'' Trunks Saga, Super Saiyan Rosé Goku Black uses his Fierce God Slicer technique, creating a scythe variation of it. He uses it to open a rift in space and time which creates clones that are as strong as him against Super Saiyan Blue Goku and Vegeta.

In Dragon Ball: Xenoverse, Dark Majin Buu uses the Tri-Form to overwhelm Super Saiyan 3 Goku, though the Future Warrior's intervention saves Goku and together the two warriors manage to defeat several of Buu's clones. When Goku's time on Earth is up, Dark Majin Buu tries to stop him from leaving using smaller clones of himself which the Future Warrior defeats. In Parallel Quest 31: "Majin Chaos", the player must defeat 30 small Majin Buu clones attacking West City. During one of Piccolo's training missions the Future Warrior fights some of Piccolo's clones.
