X

X is the main antagonist of the Elite Quest, Ztar Island, Minus Zone, and X Games arcs. He is also the seventh main antagonist of Silver Days. This is the original depiction of X, as created by Alex Guy.

X was an android created by an unknown scientist for the sole purpose of causing chaos, who began to work towards his own plans of gathering all the Azure Shards from different dimensions. He followed Alpha and Omega to the "base world" to find the last two Azure Shards.

Personality
X is a cruel and cold-hearted killing machine who loves to see people suffer and cares for nobody but himself. He shows no mercy to anyone and sees nothing wrong with taking the lives of others to further his goals, being responsible for the deaths of innocent people in his home universe, the Elite Squad, and the Genesis Rangers. He seems to view himself to be as powerful as a god and is extremely megalomaniacal. He views his enemies as being unworthy and do not deserve to have the power of the Azure Shards, or even live for that matter.

During the battle on Ztar Island, X displayed a very witty and arrogant personality due to his acquisition of three Azure Shards, similar to Cell in Dragon Ball Z after absorbing Android 17. According to Alpha, the thing that set X apart from the other robot models he encountered was his persistence. His goal was to do that which he was initially programmed to do: cause chaos; he continued this goal even after his rebellion against his creator.

Background
X, designated as Model X (モデル), was created by the unknown mad scientist responsible for the creation of Alpha and Omega after his previous attempts of conquering the Earth by using robot models A-W failed. One day, X went berserk and killed his creator by destroying the underground lair. When he emerged from the ruins, the sight of the destruction he'd caused made him realize just how powerful he truly was, triggering a much more evil and bloodthirsty mindset within his artificial intelligence. He began killing innocent civilians from a nearby city, and when caught on camera, he issued a challenge. X was then confronted by Alpha and Omega's friends, whom were then brutally murdered by the android.

Following this, Alpha and Omega had attempted to stop X but remained without success. In one such occasion, after defeating Alpha, X took an Azure Shard that Alpha had previously stolen from him and prepared to decimate everything around him, however, Omega used his most powerful attack to distract X, allowing Alpha to escape with Omega and two Azure Shards. Hellbent on pure power, X gave chase and decided to follow Alpha and Omega to the "base world."

Minus Zone Arc
Using his built-in scanner, the android is able to successfully locate Team Silver, and quickly moves towards them. Silver, Nexus, Alpha, Omega, and Zen split up, with Silver and Alpha going into a big cavern. X arrives and maneuvers through the cavern until suddenly stopping. After waiting, X crashes down and ambushes Silver and Alpha, tossing Silver aside after some resistance. Seeing Silver get pummeled, Alpha begins to syphon kinetic energy to power his speed and charges into a dash-type attack, allowing him to fight on par with X for a while.

While X is initially slightly overwhelmed, he breaks free and charges his own dash attack, subduing his mortal nemesis and ready to blast him into smithereens. Suddenly, X is assaulted by Silver with his sword, to which X responds by nearly crushing his throat and knocking him upward. The evil android then turns his attention back to Alpha and prepares to kill him. At the nick of time, Alpha activates his eye cannon to slightly dismember X and takes this opportunity to escape. Silver returns and accidentally opens up the Minus Zone and is sucked in with Alpha and X.

Super X
Super X (スーパー) is the form X achieved after collecting three Azure Shards, but before collecting the remaining four.

Infinite X
Infinite X (無限の) is the ultimate form of X, which he assumed after absorbing all six Azure Shards.
