Not sure what that is but DC has a lot of 7.
For heroes you have the 7 League Members and the 7 Soldiers.
For the mind you have the 7 emotional spectrum corps from the Green Lantern mythos.
For the body you have the 7 parliaments of life from the Swamp Thing mythos.
For the soul you have the 7 enemies of man from the Captain Marvel mythos.
For the divine you have the 7 aspects of god in the Spectre mythos.
For the nature of the universe you have the 7 endless in the Sandman mythos.
But here's the thing. All of them have a core seven but secretly have more.
There was extra members of the League and Seven Soldiers.
The black death and white life lanterns.
The weird minor parliaments and other earth variations like the blue or earth2's the grey.
Spectre mythos and god and heaven is all kinds of convoluted.
The other enemies of man from censorship.
Delirium was also Delight
