Ultron, the artificially intelligent robot from the movie Avengers: Age of Ultron, had devised the perfect plan. He would drop a giant rock on top of the earth, putting an end to humanity and letting nature decide who lives and dies. Using Scarlet Witch and Quicksilver as pawns, he craftily pitts the Avengers against each other to keep them busy while he works on his nefarious plans. For an all-knowing robot, Ultron is almost too fallible. Once again, he lets pride and arrogance get the better of him.
