Katchin (カッチン鋼; pronounced "Cat-cheen-kō"), also called Katchintite in Dragon Ball Z Kai, is a material said to be the strongest metal in the universe. In the English translation of the Dragon Ball manga, it is called Klangite or Kattin Steel.
During the Majin Buu Saga, Shin used his powers of Magic Materialization to summon a block of Katchin to test the Z Sword. As Goku hurled the cube at Gohan, the Z Sword proved no match for the cube of Katchin, and thus the sacred Z Sword was broken, leaving the blade no longer than a dagger and releasing Old Kai.
In the future, Shin summoned a block of Katchin to finalize Trunks' training in preparation for Babidi's arrival on Earth. As Shin about to toss Trunks the block, Kibito sensed Babidi's movements so the Katchin was not used.
In the Dragon Ball Super manga version of the "Future" Trunks Saga, the conflict between Goku and Fused Zamasu, Fused Zamasu is able to summon a block of Katchin and hurls it towards Goku, then proceed to spawn four more Katchin Blocks, which greatly damaged Goku. After Vegito greatly pummeled Fused Zamasu and was about to finish him off with a Final Kamehameha before defusing, Fused Zamasu hurls a block of Katchin at him, before following up with several more blocks of Katchin.
Video Game Appearances
In Dragon Ball Z: Buu's Fury, there is a wall made of Katchin in the Cave of the Ancients on Grand Kai's Planet. Unable to break it even with a Kamehameha, Goku uses Instant Transmission to pass the wall and get the ancient artifact hidden inside. Later in the game, Shin makes a block of Katchin appear in order to test the Z Sword like he did in the manga/anime.
In the Budokai series, one of the Shin's special attacks involves him summoning a block of Katchin and throwing it at his opponent (technique called Supernatural Abilities in Budokai 3). In the Budokai Tenkaichi series, the block is used in the basic rush of Shin. In Dragon Ball Z: Budokai Tenkaichi 3, Shin's downward hypersmash is hitting the opponent with a block of Katchin.
In Dragon Ball Online, it is mentioned that the Groundbreaking Science article "Katchin Can Be Cut!" has an immense influence in the birth of the Swordsman class in the game as it inspired Goten and Trunks to study swordsmanship, with them later founding the Kikoukenjutsu Sword School which would play a key role in combating an invasion of Earth by remnants of the Frieza Force, as Goten and Trunks used their sword skills to defeat the Frieza Force's army of Jigglers, who proved to be impervious to guns and traditional martial arts techniques.
In Dragon Ball Z: Kakarot, it is revealed that Katchin is a natural occuring Mineral Deposit found in certain rocks on Earth and the Sacred Land of the Kais. These rocks act as barriers that characters can break based upon the Level of Kachin (for example Level 10 Katchin can only be destroyed by a Level 10 character). They usually block the entrances of caves and destroying them allows characters access to items and Minerals within said caves. Once destroyed they remain destroyed and unlike other Mineral Deposits, they do not leave behind any minerals. Additionally as part of the -Trunks- The Warrior of Hope DLC, Future Shin uses Katchin as part of his Kinetic Bullet Super Attack where he uses Magic Materialization to create eight Katchin cubes in an X-shape pattern which he launches at the opponent via Telekinesis. Future Trunks can also find two Level 45 Katchin rock barriers in the Sacred Land of the Kais, both of which block the entrances to caves containing D Medals, Mineral Deposits, and one rare Secret for Success gift item per cave (specifically Secret for Success: Training & Secret for Success: Z Warriors).
- Length - This screenshot shows the Katchin cube to be about 70% taller than Goku, whose height is 1.75 m, therefore the Katchin cube of Katchin has a length of about 3 meters.
- Volume - Since its length is about 3 meters, the Katchin cube has a volume of about 27 cubic meters.
- The name Katchin comes from the Japanese カッチン, or kachinko. "Ko" refers to a type of metal, so the name is literally Katchin Metal. Katchin is an onomatopoeic expression that sounds like two swords clanging together.
- In the Dragon Ball manga chapter The Zeta Sword, Viz attempts to capture this pun by calling the metal Klangite. Klang is another onomatopoeic expression for clanging, and the -ite suffix has roughly the same meaning as the Japanese ko. However, in the Dragon Ball Super manga chapter "Future" Trunks' Past, the metal is instead called Kattin Steel, a different way of translating the name. However, this discrepancy between translations appears to have been fixed by The Potara's True Worth, as the metal is once again referred to as Klangite.
- "Kachinko" also rhymes with pachinko, a popular game in Japan.
- The Funimation dub of Dragon Ball Z Kai refers to Katchin as Katchintite.
- Katchin was most likely the strongest material known to most, or all universes before Katchi Katchin is introduced, as the Grand Priest uses it as a reference to multiple universes to show the strength of Kachi Katchin.
