ChaosLord
ChaosLord is the Ultimate Organism, the single most powerful being in the universe. He resides in Chaos Tower, a huge, black tower with 100 floors, which is so high that it reaches up to the dark storm clouds in the sky. Guarded by countless invincible dragons inside his tower, he lies far beyond the reach of any foe in existence.
Here are some of ChaosLord's attacks:
Unsurpassed Battle Experience: During the great war against the dragons of Dragon Planet, ChaosLord faced and defeated literally countless dragons, far more than anyone else who participated in the war. The amount of kills he was responsible for far surpassed even the three Chaos Generals combined, and the untold amounts of destruction he caused with his attacks scarred most of Dragon Planet's surface, making it evident that he had actually been fighting long enough to travel across the entire planet, taking the lives of innumerable dragons on his way. By far, he gained the most battle experience out of anyone else in the war, having fought countless battles, and as a result, bearing witness to every single type of ability and power there is in existence, analyzing them and coming up with effective ways to counter them, or other times replicating them for his own use. Having fought such an amount of battles and winning every one of them, ChaosLord has mastered the art of battle completely, knowing about every single technique that exists as well as how to counter them effortlessly. There is absolutely nothing which can be new to ChaosLord anymore, as he's already seen it all, including the powers of the Grand Beings themselves, and can effectively deal with anything. At this point, nothing stands as a challenge against the Ultimate Organism, who has reached the Peak of Evolution through the inconceivable amounts of experience he gained during that war. Even the Chaos Generals, the three most experienced beings in existence after ChaosLord, have not seen anywhere near as many battles as him, even though they have also seen just about everything there is to see in battle. It is this experience which makes all other living beings seem like infants before the OverLord of Chaos, and it was also the reason why he managed to overcome even the Grand Beings themselves, who, although they possessed godly powers, had nowhere near the experience of ChaosLord in battle, which ultimately led to ChaosLord seeing through and coping with their ultimate attacks, as well as developing his own, supreme Ultimate attack, Chaos Cannon.
Utmost Elemental Mastery: Having fought countless battles, ChaosLord has seen all kinds of elemental techniques that exist, analyzing them and replicating them for his own uses. During his innumerable fights against the dragons, he both kept using and kept getting hit by such attacks countless times, until eventually, after a certain point of countless years of fighting, his understanding of those techniques reached such a level that he completely mastered the manipulation of all elements in existence, and also developed a natural immunity to them after being exposed to them for such an insanely long amount of time. Now, ChaosLord stands as a complete master of the elements, handling them as effortlessly as making a thought about them. No elemental attacks of any kind, regardless of their power, can ever harm ChaosLord anymore, as his power over the elements is such that he could effortlessly tame the Element Gods themselves and bring them under his control, if so he wished. In fact, ChaosLord can disable any being's elemental powers just by briefly looking at them, exercising control over their own elements and suppressing them to a point where they are no longer able to use them.
All-Perceiving Analytical Capabilities: Although ChaosLord was already extremely powerful to begin with, he has always been highly observational and analytical during his battles, trying to harness as much experience and knowledge from every battle as he could. As a result of his constant awareness and analyzation of things, as well as the unfathomable amount of experience and knowledge he gained after fighting his way through an endless series of battles, ChaosLord's perception reached an entirely new level from the other beings in existence, starting to become aware of things that ordinary beings would never even begin to imagine. Though he could already think and analyze of multiple complicated things at a time as he was a machine, ChaosLord constantly continued to hone his abilities so much, to the point where he eventually started reaching the level of awareness of Overlord GAIA himself! By the time he faced against the Grand Being, he already had the grounds to understand and counter his otherwise unexplainable techniques, which he quickly did. Matching the level of the very Grand Being of Thought, ChaosLord reached the top beyond which there is nothing more to see. His supreme perceptional and analyzational capabilities, which are on the peak of all existence, mean that there is nothing in the world that he can not see through, and absolutely nothing that can get him in a battle.
