When Moya entered his third form, he would lose his reason, leaving behind only his killing instinct. He could only use his anger and hatred to support his basic movements. As for Leonis, he was stronger, so he was able to maintain his consciousness in his third form.
However, after Leonis entered his fourth form, he clearly was not able to maintain his reason. His eyes were only filled with killing intent and rage. He only had one enemy in mind, and everything else was an existence that apparently did not matter to him.
At that moment, he was not the king of the Transcendents, but an angered avenger.

It was the same with the wall and the audience stands connected to it that separated him from the wretched human!
