Will Ospreay

Ospreay made his professional debut at the co-promoted BritWres-Fest on 1 April 2012 as the masked character Dark Britannico,[6] the evil twin of Leon Britannico who was played by Paul Robinson, Ospreay's future tag team partner in the team The Swords of Essex.[7] While wrestling with Lucha Britannia he twice won the Lucha Britannia World Championship.

Ospreay soon became a regular for Progress Wrestling, debuting for them at Chapter Two: The March of Progress with Alex Esmail in a loss to The London Riots (James Davis and Rob Lynch). His performance earned him a place in the Natural Progression Series I tournament, aimed at scouting and showcasing new wrestlers. He lost in the first round to eventual winner Mark Andrews in November and again in a rematch the following May. Andrews who, as part of his reward for winning, picked Ospreay to enter the following Natural Progression Series tournament. The two met again in January 2014 in the first round of the Progress Tag Team Championship tournament, with FSU (Andrews' team with Eddie Dennis) defeating The Swords of Essex (Ospreay's team with Paul Robinson).

In his Natural Progression Series II opening match, his opponent Zack Gibson tried to win by holding the ropes. Robinson prevented Gibson using the ropes, which in turn distracted the referee for long enough for Gibson to low-blow Ospreay and make Ospreay submit.[8] On 18 May, The Swords of Essex were one of the final two teams standing in a four-team elimination match to decide contenders to the Progress Tag Team Championship. During the match, Ospreay, having been isolated for some time, reached out to tag his partner but Robinson jumped off the apron and walked out on Ospreay. Ospreay was left on his own and lost the match, after which the Progress Champion Jimmy Havoc came to the ring and ordered London Riots to tie Ospreay. Havoc pulled out a knife and threatened to torture Ospreay, blaming it on Ospreay's popularity with the fans, before other wrestlers came out and intervened, freeing Ospreay.[9] Havoc and The London Riots formed an allegiance known as Regression, which also featured Robinson.

On 27 July, Ospreay entered the eight-man, staggered entry elimination Thunderbastard match, the winner of whom can pick a time for a Progress Championship match. Ospreay entered the match third and was immediately low-blowed by Robinson, who had already entered, who disqualified himself in the hopes of taking out Ospreay. Ospreay recovered and eventually eliminated Marty Scurll last to win Thunderbastard.[10] The following show saw Ospreay team up with FSU and Noam Dar in an eight-man tag team match with FSU and Havoc's respective titles, Ospreay's title contendership and everyone else's Progress contracts at stake, depending which individual lost. During the match, Ospreay moonsaulted from the Electric Ballroom's balcony onto his opponents, on the floor.[7] Later, he had Havoc in position to be pinned but as he jumped from the top rope, Robinson dragged Havoc outside, leading Ospreay to pin Davis and end the London Riots' contract with Progress.[11]

At the next event, Ospreay defeated Robinson and announced he would invoke his Thunderbastard right to challenge for Havoc's championship at the following show. He lost the championship match in January after Havoc loosened the top rope, making it more difficult for Ospreay to do high-flying moves, and used it as a weapon.[12] During the Spring Bank Holiday weekend, Ospreay defeated El Ligero, Mark Haskins, Roderick Strong and Zack Sabre, Jr across two days to win the first Super Strong Style 16 tournament and once again lay claim to Havoc's championship.[13] Their rematch took place on 26 July in a no disqualification match where the reinstated London Riots neutralised the threat of Robinson's interference and Ospreay ended Havoc's 609 day reign to become Progress Champion.[14]

Ospreay successfully defended his title against the 2015 Thunderbastard Haskins and then Robinson. Robinson attacked Ospreay after losing to him, but Ospreay was saved by a returning Mark Andrews. Ospreay went on to finally beat Andrews to defend his title. Ospreay also headlined Progress' first main show outside of London in Manchester, in a triple threat match against Zack Gibson and Morgan Webster to close out 2015.

He lost the championship on 24 January 2016 to Marty Scurll when the referee stopped the match as Ospreay had passed out while being handcuffed in Scurll's chickenwing submission. Ospreay lost a rematch with Scurll at WrestleCon Supershow in Texas, USA in April and also lost a contendership match against Haskins on 31 July. He spent the rest of the year in showcase matches against non-regular Progress wrestlers, losing to Zack Sabre Jr., Shane Strickland, Matt Riddle and Adam Cole. Finally on 30 December, at a card composed exclusively of unannounced matches, Ospreay lost to Havoc. After the match Havoc invited Ospreay to join him in his fight against British Strong Style, who held the World and Tag Team Championship. Ospreay instead attacked Havoc and then realigned with Swords of Essex partner Paul Robinson. Ospreay attacked Havoc again, during the latter's Progress World Championship match leading to a Fans Bring The Weapons match in March. During the match, Ospreay challenged Havoc to put their Progress contracts at stake before losing the match and leaving the promotion.

Ospreay returned at the last event of 2017 as a mystery opponent for Progress Champion Travis Banks, however he lost the match.[15] On chapter 61, Ospreay defeated Adam Brooks, this was his first victory in the promotion since losing the Progress Championship in 2016.[16] At Progress Chapter 66, Ospreay defeated Mark Haskins.

On 7 May 2018, day 3 of the 2018 Super Strong Style 16 tournament, Ospreay challenged Jimmy Havoc to a match at Wembley Arena on September 30, 2018, but was forced to withdraw due to contractual obligations with New Japan Pro-Wrestling. The match was then set for Chapter 75, with Ospreay emerging victorious in a no disqualification, 2 out of 3 falls match with former tag team partner Paul Robinson as referee. At Chapter 82: Unboxing Live, Ospreay and Paul Robinson defeated Aussie Open (Kyle Fletcher & Mark Davis) to become the Progress Tag Team Champions.

On 17 May 2023, it would be announced that Ospreay would return to Progress as part of the 2023 Super Strong Style 16 tournament.[17] Ospreay's first match back would be against Tate Mayfairs, which he would win. His second match would be against Nathan Cruz, where he would lose by DQ and thus be eliminated from the tournament but reforming the Swords of Essex when his former tag partner Paul Robinson would come out to give his support.[18] On Day 3, although being eliminated from the tournament, The Swords of Essex would be assisted by Callum Newman to take on CPF in a tag match in a winning effort. It is currently unknown what Ospreay's plans with Progress Wrestling are after this event.

Ospreay has regularly wrestled for International Pro Wrestling: United Kingdom (IPW: UK) since September 2012 in singles matches, with Robinson as Swords of Essex and with Tom Dawkins as Spitfire Britannia, playing off their alter egos Pure Britannico and Neo Britannico for Lucha Britannia. Ospreay made it through to the final of the UK Super 8 tournament in both 2014 and 2015, losing to Zack Sabre, Jr and Rampage Brown respectively. He won the 30-man Battle Royale 2014 in April but failed to win it the following year when the All England Championship was on the line. On 28 March 2016, Ospreay lost a Loser Leaves Town match to his former Spitfire Britannia partner Dawkins.

The Swords of Essex began wrestling for Future Pro Wrestling (FPW) in May 2013 and after a series of wins became the first FPW Tag Team Champions after winning a four-way match. They held the titles for nine months and eventually became embroiled in a Best of Four match series against both The London Riots and The Alpha Males (Iestyn Rees & Charlie Garrett) for the FPW Tag Team Championship. The Swords of Essex failed to win a match in the series, with Ospreay wrestling the final match, which also had the London Riots' IPW:UK and New Generation Wrestling Tag Team Championship on the line, without Robinson. Ospreay has been unable to replicate similar success as a singles wrestler, twice entering the Zero G tournament but failing to win.

Ospreay also became a regular for Southside Wrestling Entertainment (SWE) from March 2014 onwards. After failing to win the Speed King Championship from Kay Lee Ray in a co-promoted show with Combat Zone Wrestling in October, he won it a fortnight later in a Six-Way Elimination match. He defended it over the following months to many SWE and guest wrestlers, eventually putting it on the line in the annual Speed King Tournament where he beat Mark Andrews in the semi-final in a Best of Three falls match but lost the title to El Ligero in a Six-Way Elimination match on 30 May 2015. The following March he unsuccessfully challenged Joseph Connors for the SWE Heavyweight Championship but on 7 August won the Speed King championship for the second time from Andrew Everett.

On 27 August 2016 Ospreay posted a Facebook live video unveiling a new British Triangle Championship with his three Swords of Essex partners Paul Robinson, Jerry Sevanchez, and Scott Wainwright. They announced that the trios championships were not specific to any promotion and could therefore be defended anywhere.[19]

Ospreay wrestled a series of shows across 2016 for What Culture Pro Wrestling for both their weekly YouTube broadcast and iPPV shows, scoring wins over Noam Dar, Marty Scurll and feud with Martin Kirby.[20] On WCPW Loaded #15 Ospreay defeated Martin Kirby with help from Adam Pacitti, Paul Robinson & Scott Wainwright, joining the Pacitti Club. At WCPW True Destiny, Ospreay teamed with Scotty Wainwright and defeated El Ligero & Gabriel Kidd and Johnny Moss & Liam Slater and Prospect (Alex Gracie & Lucas Archer) in a four-way ladder match to become WCPW Tag Team Champions.

Ospreay debuted for Revolution Pro Wrestling (RevPro) on 10 February 2013 with a win over Mike Hitchman. He soon started appearing in tag matches with Paul Robinson as The Swords of Essex and, after earning contendership with a win over The London Riots, won the British Tag Team Championship on 15 June 2013 during RevPro's first show at York Hall by defeating Project Ego (Kris Travis and Martin Kirby). After losing to Ricochet in a singles match, The Swords of Essex lost their British Tag Team Championship to Ricochet and his partner Rich Swann, The Inner City Machine Gun on 15 March 2014.

On 19 October, Ospreay beat Josh Bodom for the British Cruiserweight Championship in a match that also included Swann. The day before, he had lost a match to Matt Sydal and so in May 2015 the two had a rematch. Although Ospreay won the rematch, with their series at 1–1 the two were booked in a Best of Three Falls match with the British Cruiserweight Championship on the line. After losing the first fall, he retained the title with two straight falls. After an eleven-month reign, with a number of title defences, Ospreay lost the title back to Bodom on 5 September 2015.

Ospreay bounced back with wins over P. J. Black, René Duprée, and Ricochet, which put him in line for a three-way match for AJ Styles' British Heavyweight Championship, which also featured Marty Scurll, where the champion retained. The following day, on 3 October 2015 he lost to New Japan Pro-Wrestling's Kazuchika Okada. Okada, impressed with Ospreay, went on to recommend him to NJPW officials. This, along with endorsements from AJ Styles and Hiroshi Tanahashi, eventually led to Ospreay being signed by NJPW.[24] In 2016 Ospreay beat Scurll and the new Cruiserweight Champion Pete Dunne in a non-title triple threat match, as well as beating Mike Bailey, which saw him earn a Cruiserweight Championship match against Dunne on 10 July which he won. The following month Ospreay headlined York Hall in a match against Vader. The feud began after Vader had criticised an NJPW Best of the Super Juniors match between Ospreay and Ricochet in May, comparing the match to "a gymnastics routine".[25] The debate escalated over Twitter, with many wrestling journalists and veterans weighing in on the debate.[26] Their match eventually took place on 12 August, with Ospreay losing to Vader after Dunne interfered while the referee was distracted.
