Charybdis

Charybdis was one of the strongest and most powerful beings in the universe, possibly unable to be seen normally, and was the only being to rival The Designer. It took over The Chaos Hivemind, and was eventually defeated by the designer in a universe shaking battle that shattered several galaxies, with all damage being undone by the designer in the end. It was the only thing powerful enough to make the designer use it's true form. In many ways, it was a invasive being.

Charybdis' true name is unpronounceable, with the closest being babies crying in pain, gurgling.

Origin
Originally, Charybdis was a marine creature from the ice moon of Europa, in the milky way galaxy. It resembled a whale, squid, and a goblin shark, around 456.3 meters long and 122.8 meters tall. It was a predatory creature, feeding upon magma and sulfur. The magma superheated it into a form of plasma. The tentacles of it's original self was located at the base of it's own neck, which was used to slash prey and infest them with a organism that forces blood out, causing fatigue and paralysis in the process. The shell was covered in tar, however could not be heated up as there was a secretive enzyme on it that somehow stopped the inflammatory behavior, using the shell as defensive and offensive advantages. It glued the rivaling monster's jaws up, utilizing a similar neurotoxin, however in larger quantities that are more serrated and jagged. This leaves nasty and unhealable wounds, lest the opponent has extremely high regenerative capabilities. It was sentient, and communicated with it's mind's own power.

It was rumored to display reality changing feats, such as the ability to change the environment on a whim to suit it's needs, and that part of it's own shell was said to render viewers insane.

It displays enormous, unseen intelligence but has remained predatory thus far. It was first discovered by humanity in the 2810s (though the actual creature itself pre-dates that by millennia), attacking bases and subs on europa. It figuratively became a white whale, but as their technology grew, so did it. Getting bigger, adapting, gaining unnatural powers, it's intelligence grew as a adaption to a arms race.

Then, it was able to create a new species of sorts based off it's own image using it's reality changing capabilities, utilizing this species as it's own slaves - they were the precursors to the Cr'yggha species. Using their smaller size as a advantage, it projected it's consciousness into one of them, giving it the knowledge to build many things - tech, bio-ships, and escaped into space to the point of leaving the milky way. They had strange, immense ships surrounding the terrifying charybdis, escaping to uncharted regions of the universe. It grew larger and larger during such time, evolving and evolving, gaining powers until the point of rivaling gods.

Eventually, it literally started to eat quintillions of minds to power a supercomputer. Not only was the supercomputer used to produce weapons and tech in mass quantities. This supercomputer, however, was not used just for that. It was also used to locate a being known as the ancestor. However, the tech can't even handle the mind of charybdis, so they were used mainly to locate the ancestor's location. Due to this, it needed the minds of quintillions, something weaker then it's own, yet powerful enough to locate it.

Powers

 * Physical Capabilities - Capable of rending through planets with it's simulacra by just floating by them with an unnatural gravitational pull or outright extend it's reach with it's enormous appendages, plucking planets like literal singular grapes, to go as far as to solar systems, this is not even it's limit as the rest of it's feats are beyond the comprehension of lower organisms and that is just in it's meat puppet, what it can in it's true form is unknown to all but the Designer himself.
 * Durability and Unconventional Composition - Charybdis has insane amounts of durability in it's simulacra, able to withstand crushing blows able to annihilate entire galactic sectors to more feats that remain unknown to mortals, the meat puppet is made of matter that is said to not be solid, liquid, gaseous or even plasma, being something else entirely, all damage to it is superficial, displaying the futility in attempting to harm Charybdis--lest you are some higher being.


 * Neutron Maelstrom - Charybdis creates a 3.5 Million KM radius around it, resulting in a massive field of energy that rips open the universe and dimensions, forcing space to bend into a whirlpool with the power to destroy solar systems with no effort, eventually extending out hundreds of millions of light years across, reaching other galaxies easily as it's terrifying, tremendous and all-powerful rip consumes all that lay in it's wake. In the middle of this whirlpool is charybdis' true form, where you can see massive rows of teeth dwarfing star systems, with tentacles and claws jutting out, consuming those who fall into it. At the end, the attack and whirlpool closes and ends as the dimensions and very fabric of reality itself shakes and cracks open like glass, before eventually reforming.
 * The Truth - Charybdis utilizes a alternate form of insanity inducement in combination with this, resulting in many strange things happening to the target. They begin to hear many strange noises even if whatever could produce such isn't even there, then hallucinate everything they see as some distorted and twisted version of what once was normal. Then, the truth of not just their whole life, but who the target really is and the truth of the universe itself is revealed, breaking their perception of reality and their own mind, as they see everything fade away. Finally, and most simply, they die.
 * Consumption - Charybdis can consume everything about something, their mind, body, soul, powers and more. This allows it to gain the knowledge, abilities and powers of what it has consumed, and is partially used with the greater ability, Neutron Maelstrom.
 * Shapeshifting - Charybdis can shapeshift into anything it has consumed, is of the chaos hivemind, or is a cr'yggha.
 * Insanity Inducement - Charybdis induces insanity upon the target. In their mind, the true pronunciation of charybdis' real name is heard repetitively, initially as merely a whisper. It gets louder and louder every millisecond, eventually reaching the point that it sounds like it's yelling it out right in their ear. Eventually, it gets to the point their mind snaps, going insane and making attempts to summon charybdis, believing everything except those also mentally broken to have been replaced by some sort of imposter in attempt to defame the original. If Charybdis finds and meets one this was induced upon, it will consume the victim.
 * Regenerative Factor and Cell Manipulation - It can utilize a regenerative capability to manipulate it's cells, even to the point of growing attachments, such as pincer arms, a slug foot to crawl, and even more advanced capabilities such as massive biological plasma cannons.
 * Mind eating - Charybdis can eat minds, to power up it's supercomputer.
 * Extreme mental capacity - Charybdis has a mental capability, rivaling the designer and surpassing The A'or'i, to the point most beings and tech could not handle such mind.
 * Species creation - Charybdis, at a early level, could create species.
 * Constant evolution - Charybdis is, in a way, constantly evolving to match the current situation. It is theorized that perhaps given enough time, it could reach something far beyond it's current form, perhaps it could be a heir to the fabled and feared Ancestor, or perhaps a lower slave race that evolves to gives it mere sustenance. When it evolves, time and space warp back to their rawest forms, stars will be unbirthed across history, planets will crumble apart and be reduced to ashy, scarred versions of what once was, as Charybdis itself will fold itself into a perfected state, transcending this madness as it sees the information and structure of every Galaxy in the entirety of the Universe, down to the smallest amoeba, splitting apart several of those Galaxies into chunks, the cycles of night and day across entire solar systems are broken by Charybdis' evolution which has resulted in constantly changing day and night cycles, meteors will become larger and hit entire Planets the size of Jupiter, charybdis itself becoming above - no, downright immune, to these effects, as those who are nearby Charybdis become shattered from seeing such process take place, becoming nothing other then more food to Charybdis or even the Ancestor, they too had their collective knowledge taken by charybdis, and their powers rendered mute to charybdis' very essence. In the end, this will eventually bring fourth the returning of everything that has been destroyed or rendered malfunctional to Entropy.

Trivia

 * The character was made by Shiro, who helped to write the storyline.
 * It's origin is based off it's original concept, before it became the final concept.
