This is not an exact ordered strength from top to bottom btw.
It's more of a position based numbering.
Topman is 3. The middle. The leader position. The strongest.
Ethan and Mars are his right and left hands. So 2 and 4.
And Peter and Saturn are the weakest seemingly. So 1 and 5.
Only saturn doesn't have a paired number.
The other two pairs add up to 6.
If we consider Topman as the strongest and give him 2x3 cause he's 2 times stronger than the other scrubs, we would get 666
