Okay, I will try my best to explain what the trope is trying to show. The main point of the trope is that it's about a superpower manipulating chaos. The simple yet most potent example that I can think of would be reality-warping, where they can just change it with a thought. Other examples depend on the character, which can lead to different examples but are related to chaos one way or another:
- Nrvnqsr Chaos from the Visual Novel Tsukihime is a vampire whose body is made of chaos. He can manipulate it to create creatures made of it while also controlling their very being. Since he is made of chaos, he is harder to kill than normal vampires, where physical attacks and magic are ineffective.
- The Trickster from the Sarah Jane Chronicles is an extra-dimensional entity that changes history to cause chaos and gain power from it. Once there is enough chaos, he can fully manifest into the world.
- Martin Mystery's Chaos Beast is a manifestation of chaos that brings inanimate objects to life, turns humans into animals, manipulates the weather, and can shapeshift its form.
The reason cosmic entities are included and the like would be how they would have such power by default. If they are already so powerful or represent chaos, they would control it with ease. I am willing to hear your response when you can, and thank you for reading my post.
