My rules-
Black Eye demons aren't strong enough to bond with seraphs or Archangels and survive.
Normal angels aren't strong enough to bond with white eye, yellow eye and multicoloured demons and survive.
Cupids can only bond with black eye demons.
Rit Ziens can only bond with black eye demons.
Fallen angels can bond with back eye and crossroads demons.
Only yellow eye and multicoloured demons are strong enough to bond with archangels (and vis versa).
