In the anime, Link Joker is responsible for Reverse, a phenomenon that causes Vanguard players to lose their soul and become possessed by Void. Reversed players (players affected by the Void in this way) can reverse other players by beating them in a cardfight. Reversed players use either Link Joker decks or decks based around a Яeverse unit, a unit corrupted by Link Joker.
In the lore, the advance party of Link Joker are the Star-vaders, led by Chaos Breaker, and are directly responsible for the Great Invasion War. Their original objective was to invade worlds and purge them of life. However, Blaster Blade managed to split the seed of the void, and over time the clan has lost the will to invade and destroy, eventually becoming a regular clan of Cray, though the main force is yet to reveal themselves... Another group of Link Joker appeared; the Deletors, led by Daunting Deletor, Oksizz, who intended to destroy Cray with their planet Brandt, although Messiah managed to save Cray as well as Earth from them. Afterwards, the Messiah as well as the remains of all the Star-vaders and Deletors who died on Cray reincarnated into a new generation of Link Joker, with the Messiah becoming the clan's new leader.
Link Joker in Modern Times
"Link Joker", the invaders of the planet Cray, lost the war and failed to fulfill their objectives. Their directions have been divided into three.
The "Star-vaders" managed to escape from the planet despite their heavy casualties. They were not utterly eliminated, and some of their commanders remained unscathed. Hiding somewhere in the universe, the Star-vaders are probably preparing for another invasion.
For the "Deletors", who are bizzare beings lurking on the wandering star "Brandt", their number had been significantly reduced, but they are still wandering in the universe while preying on other lifeforms.
The Link Jokers left on the planet Cray would have faced their inevitable destruction. However, under the Messiah's will of "Harmony and Regeneration", now, they would take actions as new lifeforms---
The Factions of Link Joker, and their whereabouts
"Star-vaders", the forerunners who have destroyed many planets; "Deletors", the wanderers who trample on the milky way---"Link Joker" have released many of its factions into different dimensions, but due to their defeat in "Invasion Great War" and the dissolution of "Messiah Scramble", a great incident that takes place in a planet of another dimension that bears striking resemblance to Cray, the distribution of factions has been changed a lot. A section of "Star-vaders" managed to escape from Cray, but they failed to return to the main force, and they are hiding somewhere in the universe. "Brandt", the base of the "Deletors" which left the collision orbit without directly hitting Cray, are still wandering in the universe despite the heavy losses of fighting force. Nonetheless, the soldiers of "Link Joker" who were destroyed in the great wars exist in the most special situation. Their bodies melted into the soil of Cray after their destruction, but the substance could not be assimilated as parts of the planet because their bodies are composed of matter and energy that do not exist on Cray. Afterwards, they were reborn as new life forms that take root on Cray, by the power of "Messiah" awakened from its slumber. The birth of new lives affect the environment of Cray, for instance, spirits that produce the vital energy of "Link Joker" were born.
A central theme around all of the Link Joker's playstyles revolves around rendering their opponent units unable to be used, but does not destroy them: "Lock". The control Lock provides - while temporary - is extreme, and Link Joker uses these tactics to control the game in their favour.
Star-vaders completely focuses on Lock, and punish opponent for Locked cards they have and even force the opponent to put cards on the field as Locked in case they try to leave their rear-guard circles empty. Some also ultitise Omega Lock to prolong the penalty.
Messiah focuses on manipulating Lock by ultitise the Lock on both player and Unlock them for a bonus. By unlocking your own rear-guards during the Battle Phase you can do more attacks because units are unlocked as Stand. They also use Omega Lock
Deletors on the other hand focus on Delete, which reduces the opponent Vanguard's power to 0 to facilitate rushing and nullify their effects. Deletors don't have any restrictions to their effects and also include some locking.
The clan has 3 distinct themes, the Star-vaders are cybernetic beings, which is apparent in their predominantly metallic designs. They also typically have a/multiple Black Ring(s) somewhere on or around them. Their naming patterns are science (mostly physics/quantum physics) themed, inspired by famous theories such as Chaos Breaker Dragon and the Chaos Theory, elements of the periodic table such as Shockwave Star-vader, Dysprosium and Dysprosium, or space/nebula instances, such as Garnet Star Dragon and Mu Cephei.
The Deletors are aliens, and are more monstrous looking compared the sleekness of the rest of the clan, however unlike the Star-vaders, they are completely organic. Their naming patterns are as strange as their appearance.
The Messiahs are transcendent beings that could almost be considered gods or deities, and most of them hold the Planets Cray and Earth. They resemble dragons, but are sleeker and more majestic. Their naming patterns are religious and/or safety themed, such as Excelics Messiah, and Amnesty Messiah respectively.
