The reason I equated Qrow and Raven to Cu Chulainn and Scathach is simple.

While they're both based on Odin's Ravens, their family name is linked to a Celtic goddess. which implies Celtic inspirations.



Qrow is Cu Chulainn, because like Cu. Qrow's life is one unlucky misfortune after another, plus Qrow's a perpetually drunk warrior similar to Cu Chulainn being described as a warrior who walked with a drunken stagger.



Raven is Scathach, because Raven is the Spring Maiden and Scathach is known as the Witch of Dun Scaith. both are known to be one of the strongest warriors in the setting and have trained some of the best fighters (Vernal and Cu Chulainn). plus Raven presides over a Bandit Tribe, while Scathach presides over a Castle.



Salem is Tiamat because Salem is the Mother of Grimm and has birthing pits while Tiamat is the Mother of all Beasts and births them from her skin.



Good point about Yang.

I can also see Weiss becoming the Brynnhildr/Brawnhilda to Jaune's Sigurd/Siegfried.
