With the Overlord anime / novel (frankly, someone should probably read the novel as it has extra information), the main character is very powerful with loyal followers. However, he is also comically bad at management and doesn't know what is going on a lot of the time, and is kind of like "yeah, yeah" to his subordinates.

If he says any random word though, the subordinates take it as some brilliant plan which they implement and are like "brilliant plan, supreme one". Sometimes, he accidentally does something "brilliant".

His background was just an ordinary salaryman who liked to play MMO games before being transported.
