At the Omniverse's scale, Bloodlines were only divided in three categories. The same categories as Cultivation Bridges: Flawed, Perfect and Firmament.
Bloodlines stemming from Realm Wills were by default Flawed. Of course, a towering hierarchy existed, with those at the top incomparably mightier than those at the bottom. The Three Realms' Race Primogens could be considered the summit of Flawed Bloodlines.
Unlike Flawed Bloodlines, Perfect Bloodlines didn't stem from Realm Wills and usually appeared alongside them to become rulers of the concerned Realms. This was the case of the Empyrean Dragons, the Dao, Tribulation, and Immortal Blood Spirits of the Six Realms. But through natural mutation, Life or Death law manipulations, Perfect Bloodlines could also appear.
