In my novel I made it so that the amount of wings desides the amount of power you have
1 pair = low class ( devil/ fallen / angel)
2 pairs= middle class ( devil/ fallen/ angel)
3 pairs = high-class ( devil/ fallen/ angel)
4 pairs= ultimate class( devil/fallen/angel) = god
5 pairs= satan class / seraph/ cadre= elite Gods
6 pair= super devil = god king
7 pairs = low dragon god
8 pairs = mid dragon god
9 pairs = high dragon god
Top 5 strongest and thier power levels
1 - Great Red ( mid dragon god )/ Thrihexa ( raw power at low dragon god but due to insane regeneration and vitality it can fight for a long time without stopping)
2 - Ophis ( low dragon god )
3- shiva ( god king)
4 - indra ( God king)
5-Draig , Albion , Crom Cruach ( Elite God)
The amount of power level doesn't change the power rankings, Eg: draig and albion are top 5 in list because they have a absurd defense and strong attack power .
