Walter Hahn (born 20 August 1987) is an Austrian professional wrestler. As of January 2019, he is signed to WWE, where he performs on the Raw brand under the ring name Gunther, and is the reigning World Heavyweight Champion in his first reign. He is one-half of Imperium, the incumbent King of the Ring, and a former one-time and longest-reigning WWE Intercontinental Champion. Best known by his "Ring General" (German: Der Ringgeneral) gimmick, he is characterized by his stiff wrestling style (inspired by the likes of Stan Hansen and Kenta Kobashi^[3]), and his wrestling philosophies which are signified by the "Die Matte ist Heilig" (English: "The Mat is Sacred") motto.^[4] As a wrestler, Hahn has been consistently praised and regarded as one of the best wrestlers in the world by industry journalists^[5][6][7] and fellow wrestlers^[8][9][10] alike.

Hahn is best known for his tenure in Germany with Westside Xtreme Wrestling (wXw) as well as various German independent promotions, competing as Big Van Walter, Big Daddy Walter and mononymously as Walter (also stylized in all caps). Early in his early career, he competed in Japan for Big Japan Pro-Wrestling (BJW) and Pro Wrestling ZERO1 under the Big Van Walter gimmick, as well as the short-lived Gha-cha-ping. In wXw, he was a three-time Unified World Wrestling Champion and a four-time wXw World Tag Team Champion. He became one of the promotion's most respected figures throughout his tenure, leading him to become the head trainer of the wXw Wrestling Academy upon its opening in 2015 until 2020. Walter also became a popular figure on the independent circuit in the United Kingdom, the United States and Ireland respectively; among the independent promotions he competed in were Progress Wrestling, Pro Wrestling Guerrilla (PWG), and Over the Top Wrestling (OTT), where he held their respective world championships between 2018 and 2019.

In November 2018, Hahn was reported to have signed with WWE. He was assigned to the NXT UK brand, a sister brand of the American-based developmental brand NXT, and subsequently won the NXT United Kingdom Championship, holding the title in a 870-day reign, which was the longest for the now-defunct title, and is the eighth overall longest singles title reign for any WWE championship. In January 2022, Hahn moved over to the primary NXT brand in America, where his ring name was changed to Gunther, before being promoted to the main roster on SmackDown in April that year. He won the WWE Intercontinental Title, holding it for 666 days and losing it at WrestleMania 40, setting the title's record for both the longest singular reign and the most cumulative days as champion, whilst also being recorded as the tenth longest singles championship reign of any WWE title. After moving to the Raw brand in 2023, he went on to win the King of the Ring tournament and won the World Heavyweight Championship at SummerSlam in August 2024.

Walter Hahn was born in Vienna, Austria on 20 August 1987. He started getting interested in professional wrestling at a young age, after which he started tape collecting. As a boy, he tried to learn to speak English in school, but was poor at speaking it overall. He picked up learning the language again when he became a wrestler and interacted with English and American wrestlers. He began to speak English as a normal language between 2012 and 2013 when wXw expanded its roster to include more wrestlers from English-speaking countries.^[11] A friend of his taped numerous WWE pay-per-views from 1992 to 1996 in his home on the RTL and Pro7 channels and kept tapes of shows from promotions such as All Japan Pro Wrestling, and he let Hahn borrow them for him to see. He was a spectator for a number of catch wrestling shows in Vienna at an early age as well, seeing wrestlers such as Fit Finlay, William Regal and Robbie Brookside at said shows.^[3] At the same time, he began to have an interest in football, eventually playing as a goalkeeper;^[3] however, approximately at the age of 15, he quit playing football.^[12]

After he quit football, he went back to watching wrestling during the Attitude Era, and began to become inspired enough to take professional wrestling training in Vienna from Michael Kovac, a wrestler originally from Linz, at the Wrestling School Austria facility later on. According to Hahn, Kovac made him, as well as the other students, try out and practice amateur wrestling to benefit their overall professional wrestling abilities. Kovac would also charge €35 for private lessons.^[12]

At the very beginning of his career until 2014, Hahn went by the stage name Big Van Walter. The name was a direct reference to Big Van Vader, but it was not a homage. According to Hahn, commentator Mark Landauer gave him the name, and Landauer went on to tell promoters that Hahn's stage name would be Big Van Walter, which annoyed Hahn.^[12] Hahn had his first recorded wrestling match on 19 November 2005 in Bern, Switzerland, competing in a tag team match alongside SigMasta Rappo (who, at the time, was under the ring-name Sigi The SwissTank); they lost to the High Class Catch Club (Baron von Hagen and Adam Polak).^[13] At the time of this match, Walter was 18 years old. He had his first singles match on 25 March 2006 in Bad Vöslau, defeating Sigi The SwissTank.^[14] In the early months of his career, he had his first matches with future rivals and wXw colleagues John Klinger and Absolute Andy, as well as competing in matches with the likes of Colt Cabana, Pac and "Bambikiller" Chris Raaber.

According to Hahn, he wanted to initially hone his skills and train further in the United States; however, Chris Raaber wanted him to train in Japan due to the similarities within one of Raaber's trainers, Dory Funk Jr., and current puroresu trainers. Raaber reached out to Pro Wrestling ZERO1-MAX, the founded promotion of Shinya Hashimoto and Shinjiro Otani, and asked if Hahn could train with ZERO1-MAX and its heavyweight trainers, which consisted of Riki Choshu and his protege Tomohiro Ishii, and Tatsuhito Takaiwa. Hahn began training at the ZERO1-MAX dojo, which had also been a training facility used by members of the HUSTLE and Pride Fighting Championship rosters, in December 2006.^[12] Hahn was assigned the gimmick of Gha-cha-ping, the off-shoot wrestling gimmick of Hirake! Ponkikki [jp] character Gachapin.^[15] For the gimmick, Hahn had his hair dyed green and wore a mask to the ring, complete with a light green singlet with yellow and pink lines in the center, contrasting to Gachapin. He made his debut as Gha-cha-ping on 17 January 2007, teaming with Raaber (as Bambikiller) to defeat Otani and Rikiya Fudo.^[16] For two days afterwards, Hahn defeated Fudo in singles matches and then Fuyujirou Jidosha [jp]. His first loss as the gimmick came on 10 February, losing to Kohei Sato in Hiroshima; he lost to him again in Nagano on 19 February as well. His last match on the tour took place on 7 April, defeating Jidosha, as Jiro Kuruma, at the Yasukuni Shrine Sumo Wrestling Place in Tokyo.

Hahn returned to Japan in 2008, ditching the Gha-cha-ping gimmick and going as Big Van Walter, for two shows for the Makehen promotion. First, on 19 March, he teamed with Lance Archer, who went by his real name Lance Hoyt, losing to Masato Shibata (the future Mad Paulie) and Tomohiko Hashimoto. On 28 March, he teamed with Daisuke Sekimoto to defeat Shibata and Hashimoto.

In the midst of his run in wXw, in 2011, he took part in numerous shows with their main Japanese partner at the time, Big Japan Pro Wrestling. At Korakuen Hall, on 28 April, he defeated then-rookie Ryuichi Kawakami. Four days later, on 2 May, he defeated Daisuke Sekimoto to win the wXw Unified World Wrestling Championship, his second reign overall. In Yokohama, on 5 May, he teamed with Combat Zone Wrestling (CZW) owner D. J. Hyde to defeat Abdullah Kobayashi and Shadow WX. He returned to Japan in April 2012, teaming with Sekimoto to defeat Yoshihito Sasaki and BJW Strong ace Yuji Okabayashi. On 5 May 2012, Walter was defeated by Sasaki in a match to crown the inaugural BJW World Strong Heavyweight champion in Yokohama, a defeat considered vengeful for Sasaki as Walter had defeated him in a Unified World Wrestling Championship defense a year prior.^[17][18] Two months later, in July 2007, he took part in an inter-promotional tour with BJW, wXw and CZW wrestlers on a "World Triangle Night" showcase tour. The first match of the tour for Walter, on 27 July, involved him and fellow wXw wrestlers Robert Dreissker and "Bad Bones" John Klinger losing to Okabayashi, Sekimoto and Sasaki. Walter and Dreissker, who would later be known as the AUTsiders in Europe, defeated Sasaki and Shinya Ishikawa a day later. On 29 July, he and Klinger defeated Okabayashi and Sekimoto, and then defeated Okabayashi in a singles match hours later. On 30 July, he and Dreissker failed to win the wXw World Tag Team Championships, losing to the Sumerian Death Squad (Tommy End and Michael Dante).

In late 2019, it was announced that Walter would compete at BJW's Ryogokutan 2019 show, at the Ryōgoku Kokugikan, where he would team with Sekimoto to face Okabayashi and Yuji Hino. Sekimoto and Walter won the match, and it was acclaimed positively.^[19]

Immediately following his tour in ZERO1-MAX, Walter made his Westside Xtreme Wrestling (wXw) debut on 4 May 2007 as Big Van Walter, in a match that also involved Atsushi Aoki, Adam Polak, and Tengkwa on the pre-show of that year's 16 Carat Gold Tournament.^[20] Within his first full year in the company, he faced numerous wrestlers in high-profile singles and tag team matches; some of his opponents included former GHC Heavyweight Champion Takeshi Rikio, Roderick Strong, Low Ki, Drake Younger (Wuertz), Pierre Carl Ouellet, and Steve Douglas. On 22 June 2008, Walter had a high-profile tag team match at wXw and Pro Wrestling NOAH's Dead End VIII: European Navigation series, where, in Oberhausen, he and John Klinger lost to future NOAH ace Go Shiozaki and Kenta Kobashi.^[21] Kobashi would be an inspiration to Walter and his wrestling style in the years following their encounter, particularly with Walter's usage of the Burning Sword chop strike.

In 2009, Walter would align himself with trainer Tatsuhito Takaiwa, Sha Samuels, Terry Frazier and Sami Callihan to form The Catch Hoolz. Their first matches as an official unit were at the 16 Carat Gold shows that March. During the shows, Walter competed in the 16 Carat Gold tournament, defeating Erick Stevens before losing to Drake Younger between 6 and 7 March.^[22] The Catch Hoolz were later joined by Jon Ryan in September that year. Walter would have his first matches for a wXw championship on 3 October 2009, where he would have two chances at the wXw World Tag Team Championship. First, he would face the reigning champions and Catch Hoolz colleagues The Kartel (Sha Samuels and Terry Frazier) alongside Callihan as Walter's partner in a semi-final contest in a tag title tournament. During the match, Walter turned on Callihan, kicked him out of The Catch Hoolz, and became absent from the match; in the process, Walter became established as a top heel in the company. Subsequently added was Callihan's Switchblade Conspiracy partner, Jon Moxley, and they would defeat The Kartel to win the titles minutes later. At the main event of the show, Walter would align himself with D. J. Hyde to face both The Kartel and the Switchblade Conspiracy, as well as the other semi-final team of Axeman Axel Tischer and Bernd Föhr, in a four-way elimination match, which Walter lost after Hyde was pinned at the end of the match by the Switchblade Conspiracy.^[23] At the end of the year's 9th Anniversary show, he defeated Doug Williams.^[24]

In March 2010, Walter won the 16 Carat Gold tournament.^[22] At 23 years old, he became the youngest winner of the tournament at the time. He won the Unified World Wrestling Championship defeating Zack Sabre Jr. via disqualification. Within this time, Walter began to form an alliance with the Sumerian Death Squad (Tommy End and Michael Dante) as "The Mind".^[25][26] Walter lost the Unified World Wrestling Championship to Daisuke Sekimoto on 15 January 2011, but regained it on 2 May, during a Big Japan Pro Wrestling card in Tokyo's Shin-Kiba 1st Ring.^[27]

El Generico won the 2012 16 Carat Gold tournament^[22] by defeating Tommy End in the final. At Dead End XII on 19 May 2012, Generico faced Walter for the Unified World Wrestling Title, defeating Walter and ending his reign at 383 days (the second longest reign at the time in the overall lineage behind Ares' second World Heavyweight Championship reign).^[28]

At 16 Carat Gold 2012, Walter started a partnership with fellow Austrian wrestler Robert Dreissker, being dubbed "The AUTsiders" later on. Walter and Dreissker defeated Jay Skillet and Jonathan Gresham to win the wXw World Tag Team Championship at day three of 16 Carat Gold on 3 March 2013, a day after Walter failed to win his third Unified World Wrestling Championship against Axel Tischer.^[29] Their first defense of the titles came at the Hasta La Victoria Siempre Tour Finale, where they would defeat the Sumerian Death Squad and the Leaders Of The New School (Zack Sabre Jr. and Marty Scurll).^[30] During the reign they would successfully defend against the teams of Masashi Takeda and Drake Younger,^[31] Skillet and Ricky Marvin,^[32] D. J. Hyde and Karsten Beck (two allies of the tag team), and Maxi Schneider and Michael Schenkenberg. They would later lose the titles at 258 days in Hamburg during the 13th Anniversary tour to Hot & Spicy (Axel Dieter Jr. and Da Mack).^[33]

In October 2013, Walter competed at a ceremonial World Triangle League tournament with CZW and BJW wrestlers. He was one of three wXw qualifying wrestlers (alongside Dreiskker and John Klinger). Walter lost his block by losing to eventual overall winner Daisuke Sekimoto on the third day of the tournament after defeating Drake Younger and Kim Ray on the first and second days respectively.

Walter lost a top contendership match to the Unified World Wrestling Championship against Zack Sabre Jr. at Back To The Roots XIII on 18 January 2014.^[34] Starting at 16 Carat Gold 2014, he went by the ring name Big Daddy Walter. After defeating Sasa Keel (who initially won by disqualification)^[35] and Johnny Gargano during the tournament, he lost by disqualification to Axel Tischer in the semi-finals after Walter was blamed by the referee for a hit with the Unified World Wrestling Championship on Tischer, which was executed by the then-champion Tommy End, and after numerous assault attempts made by Tischer and the Keel Holding stable.^[36] Although Tischer lost the tournament after losing to Chris Hero, Walter began to blame End and the Keel Holding stable for his downfall in the tournament. Walter defeated Tischer in a 16 Carat Gold rematch on 29 March. On 5 April, Walter failed to win the wXw Shotgun Championship against Axel Tischer in a match that also involved Chris Rush and Drake Younger. He lost in the finals of the Mitteldeutschland Cup that year to Axel Dieter Jr., in a match that also involved Da Mack and Karsten Beck. During the evolving rivalry with the Sumerian Death Squad and Keel Holding, Walter won the annual Shortcut To The Top battle royale on 31 May.^[37] On 27 July, Walter defeated Tommy End to win his third Unified World Wrestling Championship.^[38]

His first successful defense was two months later on 20 September, defeating Sasa Keel. At the World Triangle League series that year, Walter defended against Tommy End in a two-out-of-three-falls match, where End gained the first fall in nine seconds after striking Walter with a knee strike and a double foot stomp from the top rope, and Walter subsequently defeated End two falls in a row with a powerbomb and a lariat respectively. After the end of the match, End made peace with Walter, shaking his hand. During the 14th Anniversary tour, he defeated Absolute Andy, Axel Dieter Jr., and Chris Hero in title defenses. At the finale of the tour, he, along with Dreissker, Mike Schwarz and Chris Masters defeated Keel Holding in a four-on-four "relaxed rules" match.

Upon winning a 30-minute street fight alongside Dreissker and Prost (Mike Schwarz and Toby Blunt) at Back At The Roots XIV, Vince Russo made a surprise appearance and announced he had been the new investor of wXw. Russo brought out Karsten Beck still in his ring gear after his match earlier in the show, and Beck challenged Walter to an impromptu championship match. Beck defeated Walter after Russo screwed over Walter by attacking the referee and Sha Samuels assaulted Walter whilst the referee was downed. Russo took off his jacket to reveal a referee shirt and did the three count to declare Beck the champion.^[39] Later on, Walter failed to win both the Tag Team and Unified World Wrestling titles, defeating Lucas Di Leo and Peter Fischer by disqualification and losing to Beck yet again during the 2015 16 Carat Gold weekend after his AUTsiders teammate, Robert Dreissker, hit Walter with a cowbell to cost him the championship whilst former The Mind stablemate Adam Polak distracted him in a surprise return to the company.^[40] Amidst his ongoing rivalries within wXw, Walter began to ally himself with the likes of Yoshihiro Takayama, Hot & Spicy, Sean Waltman, John Klinger and more to combat Beck and his allies (predominantly the Reich Und Schön tag team consisting of Kevin Roadster and Marius von Beethoven) and Polak and Driessker's Cerberus stable. Yet again, Walter lost to Beck for the title at Broken Rulz XV.

During the ongoing feuds, Walter began to have a close partnership with Zack Sabre Jr. and Hot & Spicy. At the 2015 World Tag Team Tournament, Walter was paired with Sabre. The tournament would be for the vacated World Tag Team Championships. After defeating Karl Anderson and Doc Gallows of Bullet Club, Reich Und Schön, and the Calamari Catch Kings (Chris Brookes and Jonathan Gresham) in the earlier stages, the duo defeated reDRagon to win the titles.^[41]

On 7 November in Prague, Czechia, Walter took part in a special contest involving Nigel McGuinness being the special guest referee. He would win the match with Czech wrestler Atom, defeating Jurn Simmons and Karsten Beck. The Big Daddy Walter name was discontinued in July 2016; there on, Walter began to use the all caps mononym WALTER.

In 2015, Walter, alongside Axel Dieter Jr., Axel Tischer and Christian Michael Jakobi, the then-head booker and managing director of wXw, released an apparel brand entitled Ringkampf (German: ring fight).^[42] Its apparel became worn by all three members (except Jakobi) throughout 2015 and 2016. In 2016, however, Ringkampf evolved into a full-on stable. For months, Walter appeared to have an alliance with American wrestler Timothy Thatcher, who shared a similar style to Walter. After Dieter, Walter and Thatcher began appearing aligned with each other in August of that year in the lead up to the World Tag Team League that'd happen between 31 October and 2 November, the three, along with Jakobi, created the Ringkampf stable and began sharing its motto, "Die Matte Ist Hellig" (German: "The Mat is Sacred"). The philosophy of Ringkampf was that they would only care about the scarcity of professional wrestling and the stable's superiority over all. Walter began to incorporate the nickname "The Ring General" within this time period. Thatcher and Walter were allied together to compete at the World Tag Team League; they defeated Moustache Mountain and Los Güeros del Cielo on the first and third days of the weekend, and lost to JML (David Starr and Shane Strickland) on the second day, failing to reach the finals.^[43] Nevertheless, the team of Walter and Dieter were granted a wXw World Tag Team Championship match at the 16th Anniversary show on 10 December, against the incumbent champions, A4 (Absolute Andy and Marius Al-Ani), in a two-out-of-three falls match, which they lost two falls to one.^[44]

At a show in London on 28 January 2017, Walter lost a top contendership match to Jurn Simmons. Afterwards, Ringkampf started a series of matches with A4, who had been rivalrous to Ringkampf since the latter's World Tag Team League run. Between 11 and 24 February, Ringkampf and A4, who also competed alongside Simmons and Günter Schmid, had their overall match series tied 2-2, notably after Ringkampf's Dieter and Walter beat A4 at Dead End XVI.^[45] At a show in Düsseldorf on 4 March, Walter lost to Matt Riddle.^[46] Walter later competed at the 2017 16 Carat Gold tournament, along with the coinciding AMBITION 8 between 10 and 12 March. After beating David Starr and Marius Al-Ani by referee's decision within two days, Walter vengefully defeated Matt Riddle before losing to Ilja Dragunov in the finals of the tournament.^[46] At the AMBITION 8 tournament, he lost in the first round to Jeff Cobb.^[47]

Within 31 March and 6 June 2017, Walter failed to gain the Unified World Wrestling Championship thrice by losing to the incumbent champion, Jurn Simmons. First, on 31 March, he lost to him by pinfall in a singles match in Ludwigshafen, then lost in a four-way match that also involved Axel Dieter Jr. and Mike Bailey on 8 April in Dresden,^[48] and finally during another singles match in Erfurt. It was announced in April 2017 that Axel Dieter Jr. would leave wXw to sign with WWE.^[49] He failed to win the Shortcut To The Top battle royale on 1 July. At Inner Circle 4 on 5 October 2017, amidst the World Tag Team League weekend, he defeated Thatcher in an "AMBITION rules" match.^[50] At the same time, they were partnered up in the league itself. They advanced in their block, defeated The Briscoe Brothers and EYFBO in the process, whilst losing to Homicide and Low Ki, They defeated David Starr and Jurn Simmons in the finals of the tournament, and, in the process, also won the wXw World Tag Team Championships, his third overall reign.

On 15 October 2017, in Leipzig, Walter failed to win the Unified World Wrestling Championship again, this time in a no contest in a four-way match against incumbent champion John Klinger (who had become the biggest heel in the company with his faction RISE), Ilja Dragunov and Jurn Simmons. Thatcher and Walter's first defense as World Tag Team Champions came on 3 November, defeating Bobby Gunns and Jaxon Stone. The next day, on 4 November, they successfully defended against RISE members Da Mack and leader John Klinger. They defeated them again, successfully defending the titles, on 17 November, whilst defeating Stone and Gunns again the next day in a tornado-tag elimination match. They defeated Julian Nero and Dreissker on 8 December, with Dreissker now going by the name Avalanche. On 23 December, at wXw's 17 Anniversary, Walter and Thatcher defeated Tarkan Aslan and his brother Lucky Kid in another successful defense.^[51]

At the 16 Carat Gold 2018 weekend, Walter was scheduled to compete in a wXw Unified World Wrestling Championship match at the Saturday show against John Klinger. However, Walter announced before the beginning of the match that the stipulation had changed to a three-way and, subsequently, Ilja Dragunov returned to the company to face both Klinger and Walter. Dragunov defeated both to win the championship, after striking Klinger with his Torpedo Moskau maneuver.^[52][53] The next day, Thatcher and Walter lost their tag titles to Klinger and Da Mack.^[54]

Between 24 March and 5 May, Walter failed to, yet again, win the Unified World Wrestling Championship. Dragunov would defeat Walter, alongside David Starr and Travis Banks, at a show in London on 24 March,^[56] and then defeat Walter in 3 straight championship matches on 13 April 14 April and 5 May^[57] in Limbach-Oberfrohna, Dresden and Oberhausen^[57] respectively.

During the 2019 16 Carat Gold tournament between 8 and 10 March 2019, Walter lost in the finals to Lucky Kid after he defeated David Starr, Fenix and Avalanche in the previous stages.^[59] At Superstars of Wrestling on 1 June, after Walter defeated Wheeler Yuta earlier in the show, Walter and Ilja attacked Aussie Open and "Hardcore" Bob Holly after their match on the show. During the assault, Walter and Ilja attacked the wXw fans and stated that the "hard work [they] put in ... is the only reason wXw is able to have people in attendance". At the Shortcup To The Top 2019 event on 3 August, he and Ilja Dragunov defeated Aussie Open to win the World Tag Team Championships, with Walter now being a four-time tag champion.^[60] On 3 August, Walter failed to win the Shortcut To The Top battle royale again, this time losing to Timothy Thatcher. On 9 August in Toronto, Walter defeated Daisuke Sekimoto. On 13 September, Walter and Dragunov lost their titles to Aussie Open; they lost in their rematch clause the next day.^[61]

Due to him now being signed with WWE and performing on the NXT UK brand, his schedule became slim for independent bookings. Before the start of the COVID-19 pandemic and its spread in Germany, Walter competed on two wXw shows on 8 March during the 16 Carat Gold weekend, first defeating Shigehiro Irie on a live stream and, later, at the 16 Carat show itself, Thatcher and Walter collaborated with Daisuke Ikeda and Yuki Ishikawa, with Walter and Ikeda losing to Thatcher and Ishikawa in a tag team match.^[62] Walter had his final wXw match to date on 18 December 2021, defeating Cara Noir at their 21st Anniversary show.^[63]

On 2 June 2018, Walter made his debut for Over The Top Wrestling in Ireland, teaming with Low Ki to defeat OTT ace Jordan Devlin and rival David Starr. At OTT's next event, "That Ring Really Tied The Room Together", on 7 July, he defeated Sean Guinness. During the match, Walter legitimately bruised Guinness on his neck, causing Devlin to console Guinness backstage.^[75] This led to a match being scheduled to the OTT World Championship on 18 August for OTT's second annual WrestleRama event, where Walter would be the next challenger to Devlin in a match billed "David vs. Goliath".

The next week, after Gunther defeated Duke Hudson, Knight challenged him to a match at NXT Stand & Deliver,^[103] which Gunther won.^[104] On 5 April episode of NXT, he faced NXT Champion Bron Breakker in a losing effort, which turned out to be his final appearance for the brand.^[105] The loss to Breakker would be the last time Gunther had lost a singles match in WWE until Chad Gable in 2023, and the last time he would be pinned in a singles match until Sami Zayn at Wrestlemania 40 in April 2024.
