Morbydia drew from the European gothic doom tradition — think Paradise Lost and early Tristania — blending mournful female vocals with heavy, melody-driven riffs and keyboard atmospherics. The band released the album "Saturnia" and earlier recorded "Requiem To The Sun" through Avernus Records, building a small but devoted following in the Brazilian underground before splitting up.

Active since the early 2000s, Morcrof weaves black and doom metal through a lens of occultism, mysticism, and existential philosophy, with Latin and Hebraic titles underscoring the band's esoteric leanings. Their 2005 full-length "Machshevet Habriá (Myths and Conjectures of Creation)" stands as a cornerstone of their catalog, and they have remained prolific into the 2020s with releases including the 2022 full-length "De Pessimism Philosophiam et Dogma Nihilistic."

Mordaza is a death metal band from Acayucan, Veracruz, Mexico, formed in 2015. The band released their debut full-length, El orden del caos, in 2020 on Mexican Steel Prods, following a 2018 demo. A 2022 single, The Dispossessed, marks their most recent recorded output.

Mordeth have cultivated one of the most idiosyncratic voices in Brazilian extreme metal since the early 1990s, blending dissonant death metal with progressive structures and a persistent fascination with science fiction, futurism, and existential philosophy. Their debut "Lux In Tenebris" (1993) established the blueprint, and after a long hiatus the band returned with "The Unknown Knows" (2018) and "Hermetic Creation" (2025), both of which continued to push their sound into increasingly dense and conceptually ambitious territory.

Mordor Truckers deal in slow-burning, fuzz-heavy stoner doom with a psychedelic edge, built around the guitar work of Manuel Ceballos and a tight rhythm section driven by drummer Brendan Bazzi. Their 2023 EP "Nowhere" — recorded at Wecando Music studio in Joinville — features the tracks "Ammit" and "Mindless," showcasing the band's taste for heavy, hypnotic grooves and atmospheric heaviness.

Mordrean is a one-woman black metal project by Demona, rooted in raw, winter-drenched atmospheres drawn from anti-Christian philosophy and dark paganism. The debut demo "Under the Black Frost" arrived in 2014, and the project has continued to grow, culminating in the 2023 full-length "In Memoriam Tenebris" released through Dominance of Darkness Records.

Mordrom is a continuation of Crux Cullum, a band that ran from 2007 to 2016 before being resurrected under this name in 2024. The project blends death metal with thrash and black metal undercurrents, channeling themes of occultism, misanthropy, and anti-religion, with the album "Walking to Bloody Death" representing their current direction.

Moretools emerged from the Brasília underground with a self-titled debut that fuses death metal, grindcore, thrash, and hardcore into a relentlessly aggressive whole. The band has shared stages with Krisiun, Onslaught, and Torture Squad, and appeared at major festivals including Porão do Rock.

Morferus is a death metal band from Banfield, Buenos Aires, whose lineup includes vocalist Leandro Cabrera, guitarists Mario Meza and Sebastian Almada, bassist Denis Camacho, and drummer Pablo Meza. Their 2018 album Argentina Psicópata — a ten-track record available on Spotify — takes its lyrical themes from notorious Argentine criminal figures and cases, including El Petiso Orejudo and Robledo Puch.
