Walter Hahn (born 20 August 1987) is an Austrian professional wrestler. He is currently signed to WWE, where he performs on the Raw brand under the ring name Gunther. He is the current WWE Intercontinental Champion in his first reign and is the leader of Imperium. He is the longest reigning champion of the 21st century and the second longest reign in the championship's history.
Hahn has appeared in a number of independent promotions around the world, predominantly wrestling mononymously as Walter, most notably Westside Xtreme Wrestling (wXw), becoming a three-time wXw Unified World Wrestling Champion; Pro Wrestling Guerrilla (PWG), where he is a former one-time PWG World Champion; and Progress Wrestling, where he is a former Progress Unified World Champion. Overall, he is a five-time world champion in wrestling and the first Austrian to compete in WWE.
After signing with WWE in early 2019, he debuted on the NXT UK brand and became a one-time NXT United Kingdom Champion; his 870-day reign is the longest for the now-defunct title. He moved over to the primary NXT brand in January 2022, where his ring name was changed to Gunther, before being promoted to the main roster on SmackDown in April that year and winning the Intercontinental title.
Walter made his Westside Xtreme Wrestling (wXw) debut on 4 May 2007, in a match that also involved Atsushi Aoki, Adam Polak, and Tengkwa on the pre-show at the 16 Carat Gold Tournament. He defeated Zack Sabre Jr. to win the wXw Unified World Wrestling Championship on 2 October 2010 in Oberhausen, Germany. He lost the title to Daisuke Sekimoto on 15 January 2011, but won it back later that year on 2 May 2011, during a Big Japan Pro Wrestling card in Tokyo, Japan. He would then hold the title for 383 days, before losing it to El Generico on 19 May 2012. In early May 2012, Walter was defeated by Yoshihito Sasaki in a match to crown the inaugural BJW World Strong Heavyweight champion in Yokohama, Japan. He won the title for a third time on 27 July 2014, defeating Tommy End at Fans Appreciation Night, then lost it to Karsten Beck on 17 January 2015.
Walter and partner Robert Dreissker defeated RockSkillet (Jay Skillet and Jonathan Gresham) to win the wXw World Tag Team Championship at day three of 16 Carat Gold on 3 March 2013. They would later lose the titles in Hamburg, Germany to Hot and Spicy (Axel Dieter Jr. and Da Mack). He partnered with Zack Sabre Jr. to win the vacant wXw World Tag Team Championship on 4 October 2015 in the finals of the 2015 World Tag Team Tournament, but relinquished the title at the wXw Fifteenth Anniversary Show on 12 December 2015, losing to Cerebrus (Ilja Dragunov and Robert Dreissker). Walter and Ringkampf stablemate Timothy Thatcher defeated Massive Product (David Starr and Jurn Simmons) to win the wXw World Tag Team Championship in the finals of the 2017 wXw World Tag Team League on 8 October 2017. On 11 March, WALTER and Thatcher lost the wXw Tag Titles to Da Mack and John Klinger. He was head trainer at the wXw Wrestling Academy until early 2020.
On 24 May 2015, Walter debuted as Big Daddy Walter in Progress Wrestling at the 2015 Super Strong Style 16 Tournament at the Electric Ballroom in London, losing to Rampage Brown in the first round. The two met again later in 2015 at Chapter 23: What A Time To Be Alive! in a match notable for the ring breaking after Brown was whipped into the corner. He entered the Super Strong Style 16 Tournament again in 2016, reaching the quarter-finals before being eliminated by Chris Hero.
Walter participated in the tournament to determine the inaugural Progress Atlas champion in 2016 but he finished the tournament with 2 points. At Chapter 47, Ringkampf (Walter, Axel Dieter Jr. and Timothy Thatcher) challenged British Strong Style (Pete Dunne, Trent Seven and Tyler Bate) for all of their championships, in a six-man tag team match, unsuccessfully challenging all of them. He defeated Matt Riddle to win the Progress Atlas Championship at Chapter 51: Screaming For Progress at the O2 Academy Birmingham. He lost the title to Riddle a little over a month later on a Progress card in New York City, but recaptured it at Chapter 55: Chase The Sun at Alexandra Palace in a three-way match that also involved Matt Riddle and Timothy Thatcher. At Chapter 68: Super Strong Style 16 Tournament Edition 2018, Walter vacated the Atlas title in order to chase the Progress world title, held by Travis Banks. At Chapter 74: Mid Week Matters, he defeated Banks to win the title.
During the 2019's edition of Super Strong Style 16, Walter defeated Trent Seven in a title vs title match, winning Seven's Progress Atlas Championship.

He would beat Sheamus in a rematch on the 7 October episode of SmackDown. Gunther spent the remainder of 2022 and the early months of 2023 retaining the Intercontinental Championship against Rey Mysterio, Ricochet, Braun Strowman, and Madcap Moss in respective singles matches on various Smackdown episodes.  
At the Royal Rumble on 28 January, Gunther was the first entrant and the last person eliminated from the titular match; he was eliminated by the match's winner Cody Rhodes, who entered as the thirtieth and final participant.
