Madman Fulton

Southwick trained to be a professional wrestler at the ASWA Pro Wrestling Training Center in Mansfield, Ohio.[3] He made his professional wrestling debut for Mid-Ohio Wrestling as Big Jake South on October 16, 2009, defeating Izzy Lambert. He won the Mid-Ohio Tag Team Titles with Cyrus Poe, and challenged unsuccessfully for various other championships within the promotion including as the Tri-County Heavyweight Title and the World Title.[5]

During his time in NXT, Southwick worked as Sawyer Fulton

In September 2012 it was reported that Southwick had signed with WWE.[3] He was later renamed Sawyer Fulton. He made his televised NXT debut on May 2, 2013, where he appeared as an enhancement talent in a tag-team match against The Wyatt Family (Erick Rowan and Luke Harper).[6] He then continued to make sporadic televised appearances on NXT as an enhancement talent over the next three years, often as part of a tag-team with Angelo Dawkins with the duo being defeated by teams such as Enzo Amore and Colin Cassady, The Vaudevillains, Blake and Murphy and The Hype Bros.[7]

In March 2016, Fulton formed a tag-team with Alexander Wolfe at NXT live events.[8] In September 2016, Fulton and Wolfe joined a stable named Sanity along with Eric Young and Nikki Cross. The stable made its debut on the October 12, 2016 episode of NXT, with Wolfe and Fulton defeating the team of Bobby Roode and Tye Dillinger as part of the 2016 Dusty Rhodes Tag Team Classic. On November 2, in the second round of the Tag Team Classic, Fulton and Wolfe beat fan favourites T.J. Perkins and Kota Ibushi. They were knocked out of the tournament in the semi finals by TM61. Fulton subsequently suffered a torn pectoral muscle which ruled him out of action for several months.[9] At the NXT tapings on November 30, 2016, it was teased that Fulton was no longer associated with SAnitY after Eric Young stomped on Fulton's jacket before kicking it out of the ring. He was later replaced in the group by Killian Dain, with no on-screen explanation provided for his absence. On November 3, 2017, Fulton was released from his NXT contract by the WWE without making another televised appearance.[10]

In Summer of 2018, Fulton began appearing as a member of Sami Callihan's Death Machines stable in Major League Wrestling, where he participated in the Battle Riot event and a War Games match.[11]

On the March 22, 2019 episode of Impact!, Southwick made his debut for Impact Wrestling under the ring name Madman Fulton as the newest member of oVe. He attacked Rich Swann and revealed an oVe shirt after taking off his jacket. Fulton made his in-ring debut on the April 5 episode of Impact! by teaming with oVe leader Sami Callihan to defeat Swann and Willie Mack in a tag team match. Fulton wrestled his first singles match for the promotion on the April 19 episode of Impact!, in which he defeated Tommy Dreamer. Fulton was mainly used as oVe's bodyguard and often teamed with them in six-man and eight-man tag team matches. At A Night You Can't Mist, Fulton teamed with Dave Crist and Jake Crist against The Rascalz in a losing effort. At Bash at the Brewery, the trio lost to Rich Swann, Tessa Blanchard and Willie Mack in a six-person tag team match. Fulton would then team with Jake Crist to take on Brian Cage and Tessa Blanchard in a losing effort at Prelude to Glory.

Fulton made his pay-per-view debut for Impact at the Bound for Glory event on October 20, 2019, where he participated in the Call Your Shot Gauntlet match, which he failed to win. At No Surrender, Fulton defeated Acey Romero, Brian Cage, Crash Jaxon and Willie Mack in a Hoss Fight Scramble. In early 2020, Fulton would engage in a feud with Ken Shamrock, which culminated in a match between the two at Hard To Kill, which Fulton lost. At Sacrifice, Fulton teamed with Dave Crist to take on XXXL (Acey Romero and Larry D) in a losing effort. At the Rebellion special, Fulton, Dave Crist and Jake Crist lost to Crazzy Steve, Rhino and Tommy Dreamer in a six-man tag team match. Later at the event, Sami Callihan ended his association with the group by attacking them during their interference in his match against Ken Shamrock. On the May 12 episode of Impact!, Fulton participated in a tournament to determine the #1 contender for the Impact World Championship, losing to Hernandez in the opening round. On the May 19 episode of Impact!, after Dave Crist lost to Crazzy Steve, Fulton attacked Dave Crist and Jake Crist and announced that he was quitting oVe, thus disbanding the group.

On the June 16 episode of Impact!, Fulton allied himself with Ace Austin by helping him in defeating Eddie Edwards in a match. The following week, on Impact!, Fulton defeated Edwards. Austin and Fulton would soon begin feuding with the debuting Good Brothers (Doc Gallows and Karl Anderson), which led to a match between the two teams at Emergence, which Austin and Fulton lost.
