Magic Materialization (物質出現魔術 Butsushitsu Shutsugen Majutsu) is a magical ability used to create physical matter out of thin air.
It is the signature ability of Gas, who uses it to create weapons out of thin air.
The user uses magic to generate whatever object they wish. Depending on the user, the range of what they can create varies.
Namekians of the Dragon Clan have the ability to create objects from nothing, and they use it to create everything from houses and furniture, and those who reach genius-class can also use it to create Dragon Balls.
Piccolo uses the Magic Materialization several times to create uniforms for himself and Gohan, as well as a few other items.
Dabura created a sword when fighting Gohan and a spear when opposing Majin Buu. Shin materialized a block made of Katchin to test the sharpness of the Z Sword. Piccolo creates an hourglass in order to show the time Super Buu has to wait for his fight with the ultimate warrior, Gotenks. Old Kai created a Crystal Ball, a highly useful device to monitor something that happens with another creature.
In the "Future" Trunks Saga, For Goku to easily contact or summon Zeno, the King of All was able to produce a handy button on his palm in an instant. In the manga, Fused Zamasu is able to use magic materialization in order to create blocks of Katchin. He is also able to restore his damaged clothing.
In the Universe Survival Saga, the Grand Minister uses Magic Materialization to create a fighting ring and spectator seats for the Zeno Expo. In the manga, Heles is capable of materializing her powerful bow and arrow. During the Tournament of Power, Saonel uses the technique to provide Pirina with a new glove after the latter regenerates his right arm.
Gas uses this ability to create weapons, which he uses as his primary method of fighting. Gas conjures things out of thin air which he uses to produce a vast arsenal of melee and medieval style weapons. He can also create multiple large, spiked walls which can use to crush his targets between. He is also shown able to manifest new clothing to replace his damaged ones.
Weapons generated by Gas
In Dragon Ball Super: Super Hero, Piccolo uses this technique on Gohan again after he neglected his training to become a successful scholar of insects.
