Hamburg Sea Devils

The Hamburg franchise was announced in November 2020, as part of the inaugural season of the European League of Football. In March 2021, ELF announced it has reached an agreement with the NFL, to be able to use the team names from the days of NFL Europe. On the same day, it was announced Hamburg will use the name of the defunct NFL Europe franchise Hamburg Sea Devils. The Sea Devils also introduced their new head coach, former special teams coach for multiple NFL teams, Ted Daisher. However, he ended up being released only 3 weeks into the inaugural season, because of "different views and expectations regarding the philosophy and leadership of our team". He was replaced by offensive coordinator Andreas Nommensen. The Sea Devils secured the first place in the Division North with seven wins and three defeats. With a 30:27 victory against the Panthers Wrocław in the semi-finals, they secured their way into the first ELF Championship Game. They faced the Frankfurt Galaxy. In a close game until the end, they lost with 30-32.

For the 2022 season, they signed Charles Jones as head coach. Jones had already coached for the old Sea Devils. From July 2022 until the end of the season, former NFL coach and coordinator John Shoop worked as a consultant for the team. Shoop was a coach for various positions on the offensive side until 2015 and among others with the Oakland Raiders Offensive Coordinator. The Sea Devils started the season with a victory over the Berlin Thunder and a defeat against the Barcelona Dragons. From week three, the team had a winning streak of ten games, defended the Northern Conference title and became the best team of the regular season. In the semi-finals in front of the local crowd, the Raiders Tirol were kept at bay with 19-7. In the ELF Championship Game against the Vienna Vikings, the Sea Devils lost with 15-27 in their second ELF championship game.

On June 11, 2023, Sea Devils played their first home game in Volksparkstadion in front of 32,500 spectators. The Sea Devils lost 22-27. With a 4-8 record, the Sea Devils missed the playoffs for the first time.

After the end of the regular season, the Sea Devils announced the dismissal of Charles Jones as head coach.
