Ludwig Kaiser Bio
Marcel Barthel, known professionally as Ludwig Kaiser, is a German professional wrestler signed to WWE, where he performs on the Raw brand and in the partner promotion Lucha Libre AAA Worldwide (AAA). Standing 6 feet 3 inches tall and weighing roughly 220 pounds, he has built a reputation as a hard-hitting, technically sound performer across the European and American wrestling scenes. Since 2008, Barthel has competed in promotions in Germany, the United Kingdom, and the United States, capturing major championships at every stop.
Early Life and Background
Marcel Barthel was born on 8 July 1990 in Pinneberg, Germany. He is a second-generation professional wrestler. His father, Axel Dieter (1933–2015), wrestled professionally and was later at ringside when his son won tag team gold in Westside Xtreme Wrestling. Axel Dieter’s life story extended well beyond wrestling, as he served as a child soldier during World War II, fighting first for Nazi Germany before defecting to France and later joining the French Foreign Legion, all before he turned 12. Despite this extraordinary early life, he returned to Germany and built a career that included raising a future world-class competitor.
Growing up around the sport, Barthel was introduced to professional wrestling at a young age and trained at his father’s side. He was formally trained by his father, Christian Eckstei, and Karsten Kretschmer, learning the fundamentals that would later define his in-ring style. The combination of a disciplined home environment and dedicated coaching laid the foundation for a career that began in regional German promotions.
Path to Professional Wrestling
Barthel debuted under the ring name Axel Dieter Jr. at NFC New Years Fight Night II on 1 March 2008, wrestling Da Mack to a time-limit draw. He made his debut for Westside Xtreme Wrestling (wXw) in January 2009, although his next appearance in the promotion did not come until July 2012, when he and Da Mack defeated Walter and Michael Isotov. Dieter and Da Mack soon formed a regular team, dubbing themselves Hot & Spicy, and quickly rose through the wXw tag team division.
On 16 November 2013, Hot & Spicy defeated The AUTsiders to win the wXw World Tag Team Championship, beginning a reign that included seven successful title defenses against international competition. In singles competition, Dieter reached the final of the prestigious 16 Carat Gold Tournament in both 2015 and 2016, while also winning the 2015 Four Nations Cup by defeating Timothy Thatcher. In late 2016, he joined the Ringkampf stable and on 10 December defeated Marty Scurll to win the wXw Unified World Wrestling Title, a reign that lasted until March 2017.
Ludwig Kaiser Career
Early Career (2008–2016)
Dieter’s early career in Germany and the United Kingdom established him as one of Europe’s most reliable in-ring talents. Alongside Da Mack, he became a two-time wXw World Tag Team Champion, known for crisp mat work and explosive striking. His appearances in Progress Wrestling alongside Walter and Timothy Thatcher in early 2017 also helped raise his profile among British audiences.
Throughout this period, Dieter built a reputation for high-level matches against top international opponents, including Tommy End, Zack Sabre Jr., and Walter himself. By the time he announced his departure from wXw in April 2017 to pursue opportunities outside Germany, he had already cemented himself as a main event-caliber performer in the European independent circuit.
WWE NXT Breakthrough (2017–2022)
On 30 June 2017, Barthel signed with WWE and was assigned to the developmental territory NXT. He made his television debut on 8 August 2018, and soon formed a tag team with Fabian Aichner. On 22 May 2019, Barthel and Aichner helped Walter retain the United Kingdom Championship, formally establishing the stable Imperium.
On 13 May 2020, Barthel and Aichner defeated Matt Riddle and Timothy Thatcher to win the NXT Tag Team Championship, beginning a 105-day reign that included defenses against The Undisputed Era and Oney Lorcan and Danny Burch. They captured the titles a second time on 26 October 2021 at NXT: Halloween Havoc, defeating MSK in a lumberjack tag team match, and successfully defended against Kyle O’Reilly and Von Wagner at NXT WarGames. Their second reign ended at 158 days on 2 April 2022 at NXT Stand & Deliver, when they lost the titles back to MSK in a triple threat match.
Main Roster Era (2022–Present)
On 8 April 2022, Barthel debuted on SmackDown under the new ring name Ludwig Kaiser, accompanying Gunther (formerly Walter) in a match against Joe Alonzo. His new surname was taken from Gustl Kaiser, a wrestling promoter active during his father’s era. On 27 May, Kaiser had his first main roster match, teaming with Gunther to defeat Drew Gulak and Ricochet. A months-long feud with The Brawling Brutes followed, during which Giovanni Vinci (formerly Aichner) returned to Imperium.
As part of the 2023 WWE Draft, Kaiser and his Imperium stablemates were drafted to Raw. On 23 April 2024, Kaiser attacked Vinci and ejected him from the group after a loss to The New Day, effectively ending the original Imperium lineup. He continued to compete on Raw through early 2025, including a triple threat win over Penta and Pete Dunne on 24 February, before disappearing from the brand for several months.
Style and Strengths
Kaiser’s in-ring style is built on hard-hitting strikes, precise submissions, and a methodical pace that frustrates opponents. Long associated with Gunther, he has developed a reputation for stiff, credible matches and for serving as a reliable gatekeeper to upper-card opportunities. His combination of size, conditioning, and timing makes him especially effective in physical confrontations.
Notable Events and Milestones
Among his signature moments, Kaiser has competed for the United States Championship on SmackDown in Berlin, challenged for the Intercontinental Championship at Survivor Series, and entered the 2025 Royal Rumble. His capture of the NXT Tag Team Championship on two occasions stands as a career-defining milestone, as does his role in establishing Imperium as one of WWE’s most dominant factions.

Across his career, Ludwig Kaiser has captured multiple championships in WWE and on the European independent circuit. In WWE, he is a two-time NXT Tag Team Champion, while in wXw he is a two-time World Tag Team Champion and a one-time Unified World Wrestling Champion. He has also won the WWE Speed Championship as part of the El Grande Americano character, a reign recognized as the longest in the title’s history at 188 days.
NXT Highlights
Kaiser’s two NXT Tag Team Championship reigns, both alongside Fabian Aichner, defined his early WWE career. Their first reign included successful defenses against The Undisputed Era, while the second was marked by a high-profile win at NXT: Halloween Havoc and a successful defense at NXT WarGames. Their losses, first to Breezango and later to MSK, came in matches that showcased all four teams involved.
Other Wins and Performances
In wXw, Kaiser (as Axel Dieter Jr.) won the World Tag Team Championship twice with Da Mack, defended it seven times in their first reign, and held the Unified World Wrestling Championship after defeating Marty Scurll. He also won the 2015 Four Nations Cup and reached the final of the 16 Carat Gold Tournament in both 2015 and 2016.

Ludwig Kaiser Family
Family Background and Wrestling Lineage
Kaiser comes from a wrestling family with deep roots in the sport. His father, Axel Dieter, was a professional wrestler who trained him alongside Christian Eckstei and Karsten Kretschmer. Axel was present at ringside when his son captured the wXw World Tag Team Championship, a moment that bridged two generations of the family’s wrestling legacy.
Personal Life
As of 2022, Barthel is in a relationship with fellow professional wrestler Tiffany Stratton, who competes in WWE. The couple has been featured together in WWE programming and on social media.
2025 Season Performance
Kaiser’s 2025 began with a high-profile Royal Rumble appearance on 1 February, where he entered at number 13 and was eliminated by Penta in six seconds. He rebounded on 24 February with a triple threat win over Penta and Pete Dunne on Raw, only to fall in a no holds barred rematch to Penta on 17 March. Following that loss, Kaiser disappeared from Raw programming for more than three months, and the Imperium faction quietly disbanded.
On 30 June, Kaiser resurfaced on Raw portraying the masked luchador El Grande Americano after Chad Gable, the original American, suffered a legitimate injury. In the role, he inherited the WWE Speed Championship from Gable and held it until 11 November, when he lost the title to Jasper Troy at NXT, ending the longest reign in the title’s history. He also expanded the character into AAA, defeating Octagón Jr. at Alianzas and competing in a four-way match for the AAA Mega Championship at Triplemanía XXXIII on 16 August, though El Hijo del Vikingo retained the title.
As 2025 closes, Kaiser leads the new Los Americanos stable alongside Rayo Americano and Bravo Americano, signaling a creative reset that blends his technical base with a masked, high-flying presentation. With his Speed Championship reign concluded and his AAA crossover established, his late-2025 momentum points toward expanded opportunities across both WWE and AAA into 2026.
