Talking about the Cosmic Storm, it is known as the universe killer mainly for four reasons.
First, its trace is unpredictable, with no fixed orbit, often appearing mysteriously out of nowhere.
Second, the core of the Cosmic Storm is the massive Gravity caused by stellar collapse. If a Planet is captured and pulled into the core, entering the Roche limit, it will be torn apart into pieces.
From this perspective, the Cosmic Storm is actually a kind of celestial body.
Third, the huge potential energy compounded during the movement of the Cosmic Storm, which is the massive wind force formed by the airflow.
Fourth, the chaotic magnetic field carried by the Cosmic Storm, which under extremely unstable conditions, often evolves into an electromagnetic storm.
These four points seem very dangerous, but if there is a way to overcome them, the Cosmic Storm is not actually scary.
