The Xezilihis Superweapon

The Xezilihis Superweapon was a weapon of mass destruction, capable of shattering a star system with little effort. It was created by The Dah'kl Empire, as a means to showcase what happens to all those who oppose their might. It was responsible for the devastating battle at Kr'Fera, which had brought down The Galactic Union's forces defending the planet by 50%. Notably, it seemed to have a superiority complex that it was the strongest in the universe.

It was destroyed when it traveled back in time to 2013 in attempt to prevent The Galactic Union from being formed, as it still hadn't fully restored the power back to the main cannon, allowing for the galactic union's forces who had followed the time rift to the past to stop it. Most of the entire fleet the union sent to stop the superweapon from erasing it from existence was lost, minus The Stallion which had ultimately overpowered and destroyed the superweapon.

Star Busting
The Xezilihis Superweapon is capable of destroying a star system effortlessly at even it's lowest capacity, and even more effortlessly at higher capacity settings, using it's main cannon.

Time Travel
The Xezilihis Superweapon can time travel, however requires all of the power from the main cannon to be diverted to the engines in order to do so. It opens up a portal, or rift, to the past or future and goes into it, warping it into the selected time period. the Effect is actually achieved by the Wormhole-like properties of this rift, imparting Energy across where it's at and its destination to destroy anything unfortunate enough to be nearby the rift, as space is bended accordingly from it, a defensive measure to prevent others from following it to the time era xezilihis is going to, eating matter away. All of this ultimately accomplishes, however in a way risky, time travel, and allows xezilihis to exceed the boundaries that is experiencing time, and when in this rift sees it as merely a function of a negative number's square root, basically making time imaginary to those in the rift until they arrive in the desired point in time, however obliterated it may of been from the rift's excess of energy, where they are then once again bound to time until or if they time travel again. the Rift also has a effect where it can throw others back into a couple seconds by force, where they wouldn't run into themselves because they replaced their past self, and because they never moved far enough past that point, effectively backtracking, although they would still perceive themselves as moving forward, so even if it duplicates oneself instead of the intended effect they'd be able to avoid collision with their past selves - this may also be another safeguard to prevent others from following xezilihis.

Mutation
The Xezilihis Superweapon has a extremely high capability to mutate living beings, via releasing radioactive toxins into the nearby areas. The said toxins can spread across 3 whole continents as quick as the toxins were sent out. The Toxin enters into others' body systems and begins to dissolve anything important, before attaching to their skin and shifting it, tearing it apart. It then cobbles together any remnants to create a horrendous creature.

Electromagnetic Pulse Waves
The Xezilihis Superweapon is able to produce a circular omni-directional wave that has a diameter of 180 astronomical units. This Wave generates and then discharges a EMP able to destroy or disable any normal vehicle, electronic devices, shelters, buildings, cities and even militarized vehicles.

Terraforming
The Xezilihis Superweapon can terraform and change a planet's landmass, size, ecosystem, environment, continents, materials, and everything else about it.

Absorption
Using the type II shield, The Xezilihis Superweapon can absorb dark energy, plasma, particle, Ion, Nuclear, and EMP blasts to improve it's shields or power.

Self Repair
The Xezilihis Superweapon is able to automatically repair, regenerate, regrow, rebuild and recreate parts of itself when damaged.

Sentience
The Xezilihis Superweapon is partially sentient, utilizing a Artifical Reasoning and Learning program, as a means to improve communication with the rest of The Dah'kl Empire aswell as the crew onboard. It also helps it for strategic analysis, political situations, and automatic targeting.

Speech Modulation
The Xezilihis Superweapon has a Speech Modulator built into it, so that it can communicate with other starships on it's own.

The Voice produced from the modulator doesn't sound robotic, or even just from a single being. Instead, it sounded as though it was several human-like voices, forming a huge and echoing chorus in perfect sync. For a short time, the superweapon even spoke on behalf of the entire dah'kl empire.

Language Identification
The Xezilihis Superweapon can re-modulate itself to identify any language it has heard, allowing for it to instantly learn and speak it as a alternative language. It can then add the language and how to learn it to the entire dah'kl empire's databanks.

Galaxy-wide Communications
The Xezilihis Superweapon is able to send a message to converse with anything, anywhere in the entire galaxy - even the very end of it. It often does this to warn systems of it heading towards them and telling them of their impending destruction at it's own hands, giving the system the option of surrender.
