Independent circuit (2007–2010) In October 2007, Parmeter stated that he was taking time off from wrestling. He returned to wrestling in February 2009, working for NWA Charlotte. On August 12, he debuted for
Florida Championship Wrestling as Ryan O'Riley losing to Conrad Tanner. He would compete under this name for a short while before becoming Conor O'Brian on September 30. On November 30, 2010, during the season finale of season three of
NXT, it was announced that Parmeter, under the name Conor O'Brian, would be appearing on season four, with
Alberto Del Rio as his mentor. He made his in-ring debut on
NXT the following week, teaming with Del Rio to defeat rookie
Derrick Bateman and Bateman's mentor
Daniel Bryan. O'Brian won his first challenge on the January 4, 2011 episode of
NXT, when he won the 'Battle of the Mic Challenge' to earn four immunity points. Two weeks later, on January 18, O'Brian was the second contestant eliminated from
NXT. Earlier that night, O'Brian competed in a match against
Ricardo Rodriguez in a losing effort. In March 2011, O'Brian was selected as one of the six former
NXT contestants to return to the show in its fifth season, NXT Redemption. During this season, O'Brian was mentored by
Vladimir Kozlov. He was later eliminated from competition on the June 28, 2011 episode of
NXT, and would later be joined, and eventually replaced, by a returning Derrick Bateman and Daniel Bryan.
First incarnation of The Ascension (2011–2012) On August 28, 2011, Ricardo Rodriguez announced the formation of a
stable called
The Ascension, with members including O'Brian,
Kenneth Cameron,
Tito Colon and
Raquel Diaz. The first match to include all members in some capacity came on September 1, 2011, and saw Cameron, Colon and O'Brian, accompanied by Diaz, defeating
CJ Parker,
Donny Marlow and
Johnny Curtis. On September 30, Cameron and Colon had a shot at the
FCW Tag Team Championship but lost to the current champions of CJ Parker and Donny Marlow. By October, however, video packages appeared promoting the Ascension under new seemingly demonic, supernatural characters, and did not include Rodriguez as he was disassociated from the team. By the end of November the Ascension had all but disbanded because O'Brian was injured, Colon had been called up to WWE to team with his cousin Primo, and Diaz became
Queen of FCW and distanced herself from the group. This left Cameron as the sole survivor of the Ascension, continuing to use the Ascension gimmick during his appearances. On March 15, 2012, O'Brian returned accompanying Cameron to the ring in his match against
Byron Saxton; the match ended in disqualification when O'Brian interfered. Cameron and O'Brian began wrestling as a tag team using the name The Ascension, and their first tag team match together came on March 23 when the two defeated
Jason Jordan and
Xavier Woods. The Ascension suffered their first loss when the pair lost to the FCW Tag Team Champions
Corey Graves and
Jake Carter, in a title match. With the conclusion of
NXT Redemption, WWE
rebranded its developmental territory FCW into
NXT. O'Brian and Cameron, as The Ascension, debuted on the June 20 episode of the rebooted
NXT taped at
Full Sail University, where they defeated
Mike Dalton and CJ Parker. The Ascension then started a feud with
The Usos, defeating them on the September 5
NXT, and also scored a win over
Justin Gabriel and
Tyson Kidd on the October 3
NXT. Two weeks later, the Ascension teamed up with
Kassius Ohno to defeat
Richie Steamboat and the Usos. The Ascension disbanded on November 30, 2012 when Cameron was released from WWE.
NXT Tag Team Champion and main roster debut (2012–2015) O'Brian retained his character while using "The Ascension" as his nickname as he started to feud with
Big E Langston for the
NXT Championship. O'Brian first faced Langston in a non-title match, which ended in a double disqualification. O'Brian then faced Corey Graves in a number one contender match which had no winner when
the Shield attacked both men to make a statement. The next week, O'Brian defeated Graves and
Bo Dallas to become the number one contender. The feud ended after O'Brian was defeated in a title match on the April 4 episode of
NXT. On the May 29
