No, Stan Lee is TOAA. Jack Kirby is The Fulcrum.
On a somewhat related note, I always get a kick out of this scan that has The Fulcrum answering a phone call from TOAA.
I wouldn't even call TOAA "monotheistic." He's just an omnipotent being. He operates very differently from a religious entity like the Judeo-Christain god.
Well I guess that about answers it then. Substituting for God are two deities, based on Jack Kirby and Stan Lee. Seems pretty logical really, and pretty obvious. Since it is their creation, they would be God. So I guess when a character prays or believes in a Abrahamic religion, they're literally worshiping Stan Lee. Bit egotistic there, but whatever.
