“The opposite of a hero is not a villain, it’s a bystander.”
-Matt Langdon (The Hero Construction Company)
Lord Voldemort, a dark wizard from the Harry Potter series, plans to extend his control over the wizarding and the Muggle (non-magical) community by wiping out all Muggles and Muggle-borns. Similar to Voldemort, Emperor Palpatine (Star Wars) seeks to exert his control over the Galaxy by wiping out the Jedi. A similar theme too is seen in the X-Men, who are persecuted for their mutant abilities.
