From 2009-13, Miner took over the role of Meg Masters, a recurring antagonist and demon in Supernatural. The Writers wanted Meg's original Actress Nicki Aycox to reprise the role in later seasons, but ultimately cast Miner for storyline purposes. The character was eventually killed off later. Tim Janson of Mania gave Miner's portrayal of Meg a positive review, saying no one played Meg "with such dripping sarcasm as Rachel Miner". He felt she "always adds spice when she appears". Similarly, Diana Steenbergen of IGN felt Miner played the role "with vicious flair" and "[conveyed] Meg's brutality well, right from the beginning". As time passed, she noted that the Actress "has done well taking over the role".
