but keep in mind he is not often referenced. I mean we get alot of allusions to beings of higher power than pretty powerful entities and so on. More recently I think he has shown up in more varying capacity.
In Immortal Hulk they have The One Below All now who is sort of like the destruction evil force. TOAA is the order and so on and he is the reverse. The scale is different but to me this is stupid as it steps on alot of abstract toes but whatever.
TOBA is the source of the hulks power and so on. When he took over Hulk totally he killed Galactus and Franklin and then merged with the previous universe to become a Galactus like being to kill that one.
I mean the whole thing was stupid to me but I am not sure how TOAA factored into that. As he seemed to just not do much of anything.
There was an issue that the LT and the TOAA had a discussion, and ther LT was shocked that the TOAA told Him that there were times beings and events seemed to get even out of His control!
