Ever since Nux came out of the Illusion, the Black Hole had already been there.
An entirely different Universe was already inside him the moment he came out of the Illusion.
There were many theories regarding how this Universe was formed, none Nux was sure about, but these theories still existed and had a high possibility of being true.
Anyways, right now, these theories weren't important.
The important point was that ever since he came out of the Illusion, Nux was never a part of this Universe.
This was the reason why no Auras of any Law, no matter how powerful, worked on him. After all, these Auras used the Universe's powers to work, how could it affect a being who wasn't even the part of the same Universe.
Universe's powers wouldn't work on someone like Nux, neither would the Universe be able to sense his presence like it senses the presence of its own people.
For the Universe, an entity like Nux no longer existed.
