The setup on the side of Death mirrors that side so perfectly, it's hard to say who copied whom. Let's just say they mutually learned from each other and progressed together.
The Executioners on Death's side are the strongest, naturally, the Destroyers on that side are the strongest, both standing at the pinnacle of demigod power, just a spark away from igniting the divine fire to become gods.
Of course, that's the official statement. Some demigods at the same pinnacle level are so-called 'God-like beings', their power strong enough to rival the gods.
When gods are not within the Divine Nation, encountering these God-like beings could very likely result in a draw.
Then there are some like Wayne, clad in human skin, who haven't even touched the edges of the demigod pinnacle yet can still crush subsidiary gods who have obtained the Authority of God's Domain.
In the end, it still comes down to one saying—knowledge is power!
