Lol, Sauron couldn't stop a couple of shortys from destroying his ring despite having an evil of army of doom, Sauruman had his schemes foiled at every turn, Palpatine got thrown down a shaft by a guy he thought was loyal and had his empire destroyed by some rebels and carebears, Vader managed to miss that he had a kid for 2 decades and then turncoated, Aliens are dumb and only know how to kill and reproduce, and the Preadators routinely get beat by less impressive physical specimens with primitive technology. The point of all this isn't to flex basic scifi/fantasy knowledge, but to point out how competency is usually an illusion based more upon aesthetic and demeanor than proficiency.
