Spider-Man has faced quite a wide array of villains, from those who are downright evil, like Electro, to those who are victims more than anything, like Norman Osborn. Though all the Spider-Man movies have shown this in different ways, The Amazing Spider-Man managed to reveal the villain's humanity first before turning its characters into enemies that were slowly going mad with power. While many remember Electro's villainous turn, Dr. Curt Connors' transformation into The Lizard was another noteworthy addition. Though his fights against Spider-Man helped with this, it was more so the story of the man behind the scales that made him a standout.
