Simon (also known as Lead Savior in his first appearance) is a fictional character from The Walking Dead television series. Simon is the second-in-command of the Saviors and the personal right-hand man of the Saviors' leader, Negan. He serves as the secondary antagonist of the show from the second half of Season 6 to the first half of Season 8, the main antagonist of the second half of Season 8 (until Negan retakes that role for the finale). Much like Daryl Dixon, Simon is an original character not included in the comic book series of the same name.
