Stanley is aware that Parson is the "Perfect Warlord", and is therefore capable of defeating vastly superior armies by devising radically innovative strategies. But despite this fact, he is deeply ambivalent about allowing Parson to act as Gobwin Knob's Chief Warlord. He knows he can't predict what Parson will do if he gives him the authority to act, but he suspects that while Parson will achieve victory, that victory will come at a higher price than Stanley wishes to pay. He is deeply unhappy that Wanda became attuned to the Arkenpliers as a consequence of Parson's first victory, and is likely to be even more unhappy if Parson's second victory allows Wanda to take control of most of Stanley's Dwagons. Parson dislikes Stanley, who reminds him of every bad boss he ever had in his old life on Earth. He has almost no respect for Stanley beyond his ability to kill him/get him killed. It was recently revealed in LIAB Text 44 that while Stanley recognizes how good a warlord Parson is, he also believes that were he to recognize subordinates it would cause them to slack in their duties. He does have a few complaints such as how expensive Parson's plans tend to be and the occasional mistakes that result from his inexperience.
Stanley is also struggling with his position. He has often commented that he was happiest when he could go out to tame dwagons, fight battles, rock out, and generally be an active part in the dangers of his side. As an Overlord he must avoid any dangerous active role while his subordinates do all the things he wishes he could do.
