Ryan Parmeter (born February 6, 1980) is an American professional wrestler better known by his ring name Conor O'Brian. He is signed by WWE, under the ring name Konnor as part of the tag team The Ascension. He was part of the fourth season of NXT, and earned fourth place on the show's fifth season, NXT Redemption.
After spending four years wrestling on the independent circuit as Ryan Payne O'Reilly, Parmeter signed a WWE contract in 2005, and was assigned to Deep South Wrestling (DSW), a developmental territory, where he wrestled as Rough House O'Reilly. He won the DSW Heavyweight Championship twice, before briefly appearing in Florida Championship Wrestling (FCW). He also appeared in several dark matches prior to Raw and SmackDown, and at several ECW house shows. In October 2007, both Parmeter and his girlfriend, Krissy Vaine, requested to be released from their WWE contracts for personal reasons.
Following his release, Parmeter took time off from wrestling, before debuting for NWA Charlotte in February 2009. In July 2010, he was re-signed by WWE, and returned to FCW where he began wrestling as Conor O'Brian. In November 2010, he was announced as a participant in the fourth season of NXT. Konnor, alongside Viktor, made his main roster debut on the September 9, 2014 episode of WWE Main Event, with the duo defeating Los Matadores (Diego and Fernando) in a tag-team match to promote their NXT tag title defense against The Lucha Dragons (Kalisto and Sin Cara) at NXT TakeOver: Fatal 4-Way.
