I think that’s part of the point, but unlike a Mary Sue, he can’t get good help. It doesn’t matter if you can beat up everyone, if someone’s constantly fucking up your schemes that you have to take time out of your precious day to fix. Or worse they actively do mess it up to the point of unfixable. Also, Mary Sues aren’t typically antiheroes or in villain orientated media, since it does tie in to the wish fulfillment fantasy, and most don’t want to be straight up evil for the fun of it.
Though I think Evil Con Carne did it better. It’s a shame it got cancelled while it’s twin lasted way, way too long.
