Eclipse

Eclipse is an ancient Living Star who turned away from his kin eons ago, becoming a being of pure entropy. While the Living Stars strive to protect the structure of time, Eclipse seeks to restructure it to his own advantage. To further this goal, he created the Kra'lythe Sect, a group of followers that share fragments of his power. In recent days, he has allied himself with the wizard Mazkertis and has joined his Kindred of Dawn.

Appearance
To the uninitiated, Eclipse appears as a simple solar eclipse, albeit one that moves and destroys everything in its path. His exact size varies, changing depending on his surroundings or the current situation. Sometimes, it appears as if some kind of misty fog is crossing his surface, but this is merely the chaos energy that makes up his form realigning itself. If he needs to physically interact with anything, he shapeshifts "hands" that float in front of his main form.

When communicating with mortals, Eclipse will sometimes shapeshift burning yellow facial features so that they can read his expression. This has been described as "very unsettling" by everyone who has witnessed it, but he continues to do this as a way of unnerving the uninitiated.

Personality
Eclipse is extremely intelligent, capable of processing the thoughts and feelings of whole armies of people at once to better learn how to utilize them in his schemes. He is also very knowledgeable in the history of the Original Universe and the structure of its adjacent dimensions due to his many travels through time and beyond. Despite his vast knowledge, he is extremely secretive, refusing to share much of what he knows even with his followers unless they need to know information that is relevant to a mission. It is difficult to come to other conclusions about his personality because his motivation for wanting to manipulate time remains a mystery.

Origins
The exact circumstances surrounding Eclipse's separation from the Living Stars and his transformation into a being of pure chaos is unknown, but he and the Living Stars have been opposed to each other since the dawn of time (or very close to it). The Living Star he has most come into conflict with is TBS, who is often the first to arrive whenever Eclipse damages the timeline or the fabric of reality. Eventually, Eclipse realized that he needed to act in more than one place at once in order to succeed against the Living Stars; to this end, he created the Kra'lythe Sect and imbued them with some of his power. The being known as Quolas was apparently one of the first inducted into the sect, but it was against his will, and Quolas would end up defecting to the Living Stars many years from then. Fortunately, Genetoes was able to fill the void. Genetoes ended up impressing Eclipse so much that he made him the leader of the Kra'lythe, second only to himself.

Appearance in-game
Eclipse's first appearance in BZPB came during a battle between Deathsaurus and Yon. When Chikato made a missile fired by Deathsaurus explode, the shards of the missile melted into the floor and dark spores rose out of the ground, becoming Eclipse. Eclipse instantly nuked the battlefield with a wave of chaos energy, destroying everything in its path (but Deathsaurus, Chikato, and Yon all survived to fight another day).

Eclipse appeared again during the Battle of Mata Nui II, and attempted to sway Blackout to his cause. Mid-conversation, TBS tracked Eclipse to his present location, and appeared to fight him. Blackout wasn't impressed by Eclipse's offer either, so he blasted the black sun with lightning. This didn't harm the black sun at all, but it got the point across. Eclipse turned his attention to something else instead: a skirmish between Genetoes and Nosmilo elsewhere on the battlefield. Eclipse assisted his servant by smashing Nosmilo five miles away. Advanced Dal then appeared and attacked Genetoes, but Eclipse crushed him into a fine mist. Eclipse then sent the insides of Dal to an artificial disaster, altered time to make said disaster happen over and over again, and then sent them to another plane of existence.

Later, Eclipse started hunting down Vorahk-Kah for some reason. When he arrived at his location and saw TBS also fighting the mutated Rahkshi, Eclipse decided to join in. Despite the overwhelming odds against him, Vorahk-Kah survived, probably because Eclipse and TBS went back to fighting each other instead.

During the Battle of Lantea, Ynot decided to use the Vahi Cube. Eclipse detected the use of the cube and undid all time editing. This caused a lot of insanity, which meant that none of that ever happened.

The Mazkertis Paradox
In The Mazkertis Paradox, it was revealed that the reason the Living Stars disappeared was because they had started travelling the multiverse, absorbing their counterparts in order to increase their power. Eclipse vanished with them, leaving his loyal servants scattered and confused, but he returned to the Original Universe two years later. Strangely, Eclipse seemed to be gravely injured and in some kind of protective hibernation. He was eventually located by Genetoes and woken from his slumber. Eclipse refused to divulge what had happened to him to Genetoes, but agreed to be taken to Kalta Thaea to investigate the Kindred of Dawn. Upon hearing Mazkertis's manifesto, Eclipse agreed to join, although he probably intends to use the Kindred for his own purposes.

Abilities & Powers
Few things can hurt Eclipse, since the entirety of his form is made up of chaos energy, but what neutralizes chaos can also damage the cohesion of his form. He can use chaos energy for a variety of effects:
 * Chaos Energy Manipulation - Eclipse has complete control over chaos energy and can manipulate it in any way possible.
 * Chaos Energy Absorption - Eclipse survives on chaos energy. If he has expended too much of it, he must absorb more to continue existing.
 * Regeneration - If Eclipse's physical form is damaged in any way, he can heal himself by transfering some of the chaos energy that makes up his form to "fill the wound" of the affected area.
 * Shapeshifting - Eclipse can change his size at will. He can be anywhere from the size of a small house to the size of an average star. This is achieved by either condensing or expanding the chaos energy that makes up his form, but if he grows too big, he must absorb more chaos energy to avoid stretching himself too thin.
 * Telepathic Communication - Eclipse primarily communicates telepathically with his followers and enemies, though he has been known to speak on occasion. It is unknown if he has other telepathic abilities besides communication.
 * Teleportation - Eclipse can teleport anywhere in or outside the universe. This teleportation is often violent and bypasses the sixth dimension, causing small tears in the fabric of reality.
 * Time Travel - Eclipse can instantly travel to any time, past, present and future, though he feels a compulsion to return to the present after spending a while in a different time period.
