More than a year later, Martinez would become NCW Femmes Fatales Champion on March 30, 2013, defeating Kalamity at NCW Femmes Fatales XI, ending her 538-day reign on top. She lost the title on August 16, 2014. On May 6 2017, at Challengemania 25, Mercedes came back to defeat Stefany Sinclair and reclaim the NCW Femmes Fatales Championship. She left the event as a triple champion, already walking in the match with both the WSU World Championship and the Shimmer Championship.
