Mortals of a similar level. Which would be...40, or 60? I forget which.
I don't have Deities and Demigods anymore (not that is particularly valuable when talking about OOTS gods), but I do have Elder Evils, and the creature in that book with the most HD is Atropus, whose plan involves absorbing the life force of the gods it created, with 66.
