Waters made his Major League Wrestling (MLW) debut at the Blood and Thunder event on November 9, 2019. He made his televised debut in MLW on the December 7 episode of Fusion as Alexander Hammerstone's newest gift to The Dynasty under the ring name Grogan as a participant in a battle royal. He won the battle royal by lastly eliminating Timothy Thatcher. Grogan only appeared once beside Dynasty member MJF in a backstage interview with Alicia Atout on the January 25 episode of Fusion. On the February 15 episode of Fusion, Grogan betrayed Dynasty by allowing Dynasty's rival Mance Warner entry into the arena after Warner bribed Grogan by offering him beers and a date with a dancer. This allowed Warner to interfere and prevent Hammerstone from helping MJF and Richard Holliday in winning the MLW World Tag Team Championship from Marshall and Ross Von Erich. This led to Grogan officially leaving Dynasty and turning into a fan favorite and reverted to his original ring name Logan Creed.[7]

Creed competed in his first singles match on the following week's episode of Fusion by defeating enhancement talent Moonshine Mantell. On the February 29 episode of Fusion, Creed teamed with Mance Warner and Savio Vega against Dynasty's Alexander Hammerstone, Gino Medina and Richard Holliday in a six-man tag team match, which Creed's team lost. Creed then did not compete in MLW as MLW went on a hiatus due to the COVID-19 pandemic.

Creed made his return to MLW as the masked "Black Hand of Contra" on the November 18 episode of Fusion by attacking Alexander Hammerstone after Hammerstone appeared at ringside to confront Jacob Fatu after Fatu had retained the MLW World Heavyweight Championship against Davey Boy Smith Jr. Creed was confirmed as the fifth new member of Fatu's faction Contra Unit. His ring name was later revealed to be Mads Krügger. On the December 2 episode of Fusion, Krügger competed in his first match by defeating Ariel Dominguez. On the December 16 episode of Fusion, Krügger defeated two local wrestlers in a handicap match. He was later engaged in a brawl with Hammerstone, setting up a match between the two for Hammerstone's National Openweight Championship at Kings of Colosseum.[8] Being at the Contra Unit, he was the brawn needed by Josef Samael to shield Fatu, but that ended when Fatu lost the Heavyweight title to Alex Hammerstone. That caused tension between Contra members, which went to a breaking point after War Chamber, which Fatu and him brawled after losing the main event. The duo feuded, with vignettes of him demanding that he wants Fatu fall by his hands, exchanging victories on each other, culminating in the Weapons of Mass Destruction match, which he was "drenched in radioactive waste", and Jacob unmasking him, ending the feud.

After the match, vignettes of him injured and horribly suffering due to the toxin exposure appeared on MLW programming. At the start of 2023, he was released by MLW.
