The Dark Lord (Animation vs Animator): The evil counterpart, younger brother and former best friend-turned-second arch-nemesis of the Chosen One. Upon destroying Alan's PC in Season One, he and the Chosen One went on a rampage across the Internet for two years, terrorizing websites such as Yahoo!, StickPage and Newgrounds, as well as video games such as Angry Birds, which eventually makes the Chosen One develop second thoughts about their atrocities while the Dark Lord sadistically continues without any reluctance.
