Trent Seven

Despite being a "part timer", Seven was granted a match for the Ring of Honor World Championship during ROH's 2011 tour of the United Kingdom. Seven lost to defending champion Davey Richards on 15 July 2011 on a show promoted by Fight Club Pro (FCP).[5] At some point in 2011 Seven became the first holder of the FCP Championship, holding it until 25 November where he lost the title to Eddie Edwards.[6] In 2013 he won FCP's annual "Infinity Trophy Tournament" when he defeated Mark Haskins in the finals.[7] During an FCP show on 5 February 2016 Trent Seven unsuccessfully challenged Trevor Lee for the TNA X-Division Championship.[8] On 7 January 2017 Moustache Mountain (Seven and Tyler Bate) teamed up with Joel Allen to defeat #CCK (Chris Brookes and Kid Lykos) and Shay Purser, with the win Allen became the title holder of the Attack! 24:7 Championship, only for Allen to lose it the same night.[9]

In early 2015, Seven, alongside Bate, debuted in American promotion Chikara as part of their tour of the United Kingdom, defeating The Hunter Brothers in a dark match on 3 April[10] and losing to the Devastation Corporation (Max Smashmaster and Blaster McMassive) in another dark match on 6 April.[11] In their final dark match on the tour, Seven and Bate teamed with Clint Margera to take on Pete Dunne, Damian Dunne and Jimmy Havoc in a losing effort.[12] Seven teamed with Bate and Dan Moloney at that year's King of Trios as Team Fight Club: Pro, making it to the semi-finals before being eliminated by the Bullet Club (AJ Styles, Matt Jackson and Nick Jackson).[13] In 2016, Seven and Bate began competing more regularly in Chikara, and on 21 August they defeated Los Ice Creams (Hijo Del Ice Cream and Ice Cream Jr.), N_R_G (Hype Rockwell and Race Jaxon) and The Devastation Corporation to win the Chikara Campeonatos de Parejas.[14] They were stripped of the title during Chikara's secret season 16.

Seven returned to Chikara on 1 September 2017, when he, Tyler Bate and Pete Dunne, billed collectively as "House Strong Style", entered the 2017 King of Trios, defeating House Whitewolf (A-Kid, Adam Chase and Zayas) in their first round match.[15] Over the next two days, House Strong Style defeated House Throwbacks (Dasher Hatfield, Mark Angelosetti and Simon Grimm) in the quarterfinals,[16] House Rot (Frightmare, Hallowicked and Kobald) via forfeit in the semifinals and House Sendai Girls (Cassandra Miyagi, Dash Chisako and Meiko Satomura) in the finals to win the 2017 King of Trios.[17]

Trent made his debut for Insane Championship Wrestling in early 2015, facing Mikey Whiplash at the O2 Academy Birmingham. Throughout the rest of the year, Trent would be seen competing on ICW's tour shows around the UK, quickly becoming a fan favorite.

In 2016, after returning to enter the 5th Annual Square Go match, Trent challenged Big Damo for the ICW World Heavyweight Championship, before entering into a feud with Mikey Whiplash, eventually leading to a 6 man contest at Shug's Hoose Party 3, between Legion (Mikey Whiplash, Tommy End & Michael Dante) and Moustache Mountain & Lewis Girvan. After Trent picked up the win for his team, Whiplash, who had been campaigning to main event Fear & Loathing XI, stated that he believed Trent Seven was the rightful challenger to the World Heavyweight Championship. In the months that followed, Trent, backed heavily by the ICW fans, campaigned for ICW GM Red Lightning to grant him a shot at the championship. After being disregarded by Lightning, Trent forced the GM to give him a match against Wolfgang at Fear & Loathing XI, with the title on the line inside a Steel Cage.

At Fear & Loathing XI, at The SSE Hydro, in front of the largest independent UK wrestling crowd for over 30 years, Trent faced Wolfgang in a Steel Cage match for the ICW World Heavyweight Championship. However, after being overcome with rage, Trent punched Wolfgang with his own knuckleduster on top of the cage, causing Wolfgang to fall to the floor, inadvertently winning the match. After earning himself one more shot at the title by defeating Chris Renfrew, Trent once again faced Wolfgang, at the O2 Academy Newcastle, at the 6th Annual Square Go event, and succeeded in becoming ICW World Heavyweight Champion.

Trent would remain ICW World Heavyweight Champion for 2 months, defending the title against the likes of BT Gunn, Pete Dunne, Jack Jester & Jordan Devlin, before losing the title to Joe Coffey at Barramania III. After a few months away, Trent returned briefly at Shug's Hoose Party 4, facing BT Gunn, Wolfgang, & Pete Dunne in a 4 Way Match for the WWE United Kingdom Championship. This match marked the first time the title had been defended on UK soil, outside of a WWE ring.

Trent would not return to ICW until almost a year & a half later, at Fear & Loathing XI, where he, Pete Dunne & Tyler Bate lost to the team of Wolfgang, BT Gunn & Noam Dar.

The following night, Mustache Mountain defeated O'Reilly and Strong to win the NXT Tag Team Championship, but lost the titles back to them two days at the 21 June NXT tapings (aired on 11 July) after Bate threw in the towel due to Seven's injured knee being targeted.
