Annie Martoz is the senior editor of Scorch Magazine. Incredibly anti-social and surly, she was very much against Sabrina being employed at the magazine and was constantly being mean to her. Annie was a big part of the reason that Sabrina finally decided to quit her job at Scorch and she was never seen again after Sabrina's resignation.
Though she was Sabrina's boss, she was not the boss that hired her. Although, she did eventually gain the ability to keep on, or fire, Sabrina. Her boss is the mysterious (and never seen on-screen) Johnathan, who also initially hired Sabrina at Scorch Magazine.
