Leon made her Ring of Honor (ROH) and professional wrestling debut on April 18, 2014, in a losing effort to Jenny Rose. At ROH Future Of Honor #1 in Newville, Pennsylvania.[7] Three months later Leon lost in a tag team match to Jenny Rose and Veda Scott at ROH Future Of Honor #2 event.[8]
On July 25, 2015, Leon won her first match for Ring of Honor defeating Deonna Purrazzo in a dark match.[9][10] During the ROH Reloaded Tour Leon lost to Taeler Hendrix.[11] Later that year Leon and Sumie Sakai defeated Purrazzo and Hania "The Howling Huntress" getting her second victory in a dark match.[12]

After ending her program with Hania, Leon entered a rivalry with Taeler Hendrix.[14] The two wrestled in a dark match from the July 30 episode of ROH Television.[14] Leon picked up the victory, but was attacked by Hendrix after the match.[14] The two then brawled backstage.[14] Weeks later, Leon came to the aid of Deonna Purrazzo, who was being attacked by Hendrix.[14] This led to a tag match between the three, as well as a mystery partner for Taeler, in Lockport, New York, which saw Leon pinned by Hendrix's partner, Jessicka Havok,[15][14] after Hendrix drilled her with a steel chair. These events all led to Leon and Hendrix squaring off in the first ever No Disqualification match in Women of Honor history at ROH on SBG #276, with Hendrix coming out on top after hitting her Kiss Goodnight finisher onto a pile of chairs, after Leon decided to not hit Hendrix with one herself.[16][14] Because of this loss, Leon found herself attempting to go to "a darker place", becoming noticeably more aggressive in her matches.[14] Unfortunately, the feud was cut short when Hendrix was granted her release from Ring of Honor. To write her off, Leon handed ROH commentator Ian Riccaboni a tarot card of death and said the WOH Division had been cleansed of dishonor. Leon would also wrestle her match that night with blood splattered on her body.[14]
