Oliver Carter

WWE (2019–2025)

On 19 April 2019, Sauter made his NXT UK debut as a face under the ring name Oliver Carter in a dark match, which he lost to Kassius Ohno. He was utilized as a jobber until 16 November where he ended his losing streak. He teamed with Ashton Smith to defeat The Outliers (Dorian Mak and Riddick Moss). He returned to the brand on 17 January 2020, where he teamed with Smith to defeat Pretty Deadly (Lewis Howley and Sam Stoker).

On the 2 June 2022 episode of NXT UK, Carter and Smith won the NXT UK Tag Team Championship by defeating previous champions Moustache Mountain (Trent Seven and Tyler Bate) and Die Familie (Teoman and Rohan Raja) in a triple threat match. On the 23 June episode of NXT UK, Carter and Smith were set to defend their titles against NXT 2.0's Josh Briggs and Brooks Jensen, but Smith suffered a knee injury and had to vacate them.

On the 13 September 2022 episode of NXT, a video package was shown to reintroduce Carter under the ring name of Oro Mensah. In his debut match, Mensah defeated Grayson Waller to qualify for the NXT North American Championship ladder match at NXT Halloween Havoc. At the event on 22 October, Wes Lee won the match.

On 28 May at NXT Battleground, Mensah turned heel and joined Jakara Jackson and Lash Legend in helping Noam Dar retain his NXT Heritage Cup against Dragon Lee to form the Meta-Four stable. On the 13 June episode of NXT, Mensah competed in Dar's place due to injury, losing his NXT Heritage Cup to Nathan Frazer. After turning the whole stable into faces, Mensah wrestled for Ethan Page's NXT Championship and Lexis King's Heritage Cup, but lost both times. The Meta-Four disbanded on the 29 April episode of NXT, and Mensah and Jackson were released from WWE the following week, ending Mensah's six-year tenure with the company.

Return to independent circuit (2025–present) On August 10, 2025, Sauter, under the ring name Oro, made his first post-WWE appearance at Blitzkrieg! Pro, where he was defeated by Andy Brown. On August 14, Oro made his debut for Ring of Honor (ROH), losing to Tomohiro Ishii.
