Ba'al was concerned for a second, until he realized that the Joker wasn't a mind reader. That could have been awkward otherwise. "I don't recall ever calling myself a God," he pointed out as they walked. "My more correct title would be 'Supreme Commander of the Goa'uld Empire,' or 'System Lord'. I certainly don't make any claims to Godhood." A lie, somewhat, but that was all technicalities anyway. He pretended like the names 'Superman' and 'Wonder Woman' didn't mean anything to him, figuring he would keep up the fiction of ignorance until such time as it was wise to drop it.
