Oh fair enough. Anyway:

Another God from V24 and this guy is interesting because he's from the same mythology as Azi Dahaka:

Angra Mainyu

Zoroaster's greatest god. The god who is said to have produced Azi Dahaka. In the final chapter, in response to the invitation from Tartarus, he agrees to cooperate with Hades' plan.

I don't know if he's mentioned as in he communicates non face-to-face or if he appears, but this dude is in the series. Full details on this dude:

In ancient Persian (Iran) religion and books of Zoroastrianism, Angra Mainyu is the god of darkness, the eternal destroyer of good, personification and creator of evil, bringer of death and disease. He is also known as Ahriman, and his name means "fiendish spirit". Ahriman lives in darkness, in a place where all those who do evil go to after their demise (Hell) and his symbol is the snake. He is what in Christian religion can be called Satan.

Yeah Hades's army is even more OP now.
