In fact, he only looks and acts similar to an Executioner. His divine ability is different from theirs deep down. But he won't tell the Emperor that. The Emperor might be full of knowledge that he doesn't know, but he is just an old thing that has been imprisoned for millions of years.
The Emperor noticed that he didn't believe what it said. It didn't bother to press the point. It moved on to something else. "How will you get a large number of tails then without an Emperor? Your potential will be stunted."
"What about the Executioners that I ate?"
"That won't do. You can eat other Executioners and Emperors and it will help you but you will never realize your full potential without eating your opposite. An Emperor and an Executioner are different faces of the same coin. But they are separated into different individuals. You need the corresponding face of your coin to become whole again. You need the life that is your direct opposite to your death to realize your full potential."
