No one had ever seen Jean the Time Monarch is a true fight since he joined the Republic
It is because of that no one knows how to rank him among the many heroes and heroines of the world
The consensus of many people was that Jean is powerful. But the powerful part of his abilities is not considered powerful in terms of destructive power like Death Monarch.
No one ever saw the destructive power of Jean since he joins the Republic
People who are not the people of the Republic called him Time Monarch.
After Azief called himself Death Monarch, those who believes themselves to have the qualifications had also adopted such title.
There was Oreki who called himself Thunder Monarch and then there is a few others in the world.
Those weak people did not dare using such title unless they are ready to bear the weight of such title.
