The band consists of The King (John Steen) on guitar and vocals, The Burgher (Ulrik Bostedt) on bass, and The Vicar (Tony Samuelsson) on drums.

[3] The group came together in 2002 when the trio of John Steen, Ulrik Bostedt, and Tony Samuelsson spent a year as exchange students in Colorado, USA.

They formed under the name of Märvel, inspired by the Marvel comic book heroes with a metal umlaut to help distinguish themselves from the company and reflect their gritty, hard-rock sound.

Due to travel restrictions, another bass player, The Aviator, was recruited for touring purposes as the band released their second full-length album Thunderblood Heart in September 2007.

Actor Johannes Brost was a fan of the new album, filming an unboxing, a first-listen, and reaction music video of the track "Hello!"

Warhawks of War released in 2011 on Killer Cobra Records to positive reviews with a faster, harder sound than previously seen in Thunderblood Heart.

[7] The band had multiple guest musicians join them for the album, including Robert Dahlqvist ("Strängen") and Andreas Tyrone Svensson ("Dregen") from the Hellacopters.

[9] "Danish Rush" got a music video directed by Johan Bååth (the Doits) and filmed by Peder Carlsson (Backyard Babies), which features many members of the Hellacopters and has a chiptune version of the track in the credits.

The band would travel to the United Kingdom for the first time to attend the 2016 Hard Rock Hell festival and subsequently picked up drummer Tony Thornensson, with the stage name of The Charlatan.

Andy Thorley of Maximum Volume Music gave it an 8.5/10 and called it "A record that, given a couple of listens, will reveal its true majesty".

[12] In 2017 Märvel would participate at the Fishbait Festival on Åland, doing a special performance with Robert "Humbucker" Pehrsson, Nicke Borg (Backyard Babies), and Sator members Chips Kiesbye and Kent Norberg.

[13] In March 2019 Märvel contributed to a collaborative album by including the track "The Devil Stole The Beat From The Lord" on Payin' Our Dues: A Tribute To The Hellacopters.

Songs such as the surf-rock "El Camino Real" by Lee Dresser and a 180 BPM version of pub-rock "Sultans of Swing" by Dire Straits.

Bands such as Thin Lizzy, T-Rex, W.A.S.P., Mötley Crüe, and RATT can be picked out of Märvel's musical style, with swinging vocals and fast guitars.
