Morbid Perversion channel the spirit of Brazilian extremity — Sarcófago, Sex-trash, Holocausto — through a bestial black/death metal attack soaked in sadism and anti-religious perversion. Founded by guitarist/vocalist Sexxxtrash and drummer Lunatic, the band spent a decade releasing tapes and 7" vinyl before collecting that material on the 2021 retrospective Morbid Skills of Evil (A Decade of Desecration), followed by Infamous Dogmas of Sacrifice in 2023.

Morbid Prophecy blend melodic black and death metal in the vein of Scandinavian acts, as evidenced by their recorded cover of Rotting Christ's "Among Two Storms." Their 2018 EP Thou Shalt Die, released through Narcoleptica Productions, showcased five tracks of sweeping, riff-driven extremity that positioned the band as one of the more melodically ambitious acts in the local underground.

Morbid Whisper plays a blunt, no-frills style of death metal drawing on the genre's classic foundations. Their 2021 debut full-length Habemus Mortem delivers eight tracks of aggressive, mid-paced death metal with an English-language lyrical focus on suffering and religious corruption.

Morbidade is a solo death metal project helmed entirely by Marco Aurélio, who handles all vocals, guitars, and bass. The self-titled debut, released in May 2020, channels old-school death metal through a lens of gore and splatter themes, keeping the approach raw and deliberately stripped down.

Morbidead began in 2014 as a solo outlet when its founder's previous band, Defecation of Putrid Blood, went on hiatus. After a long pause, the project returned with a shifted focus toward doom/death metal with thrash influences, documenting that evolution across a string of demos including The Essence of Black Forest and Gaia, The Lady of Chaos.

Morbidoom trace their roots back to 1993, making them one of the older black metal outfits from the interior of Minas Gerais. The band documented their early phase through the demo tapes Seven Swords of Lucifer (1995) and Ares... The Call of War (1999), drawing on warrior mythology and occult themes before going dormant and eventually returning to activity around 2015.

Morbo Chacaleitor is a death/thrash metal band from San Felipe, Chile. The band released two albums in quick succession: Crónicas Macabras in October 2019 and Inconsciente Asesino in September 2020, the latter a six-track record featuring Spanish-language tracks rooted in violent and urban themes.

Morbosus is a Buenos Aires black/death metal duo founded in July 2012 by guitarist Burner of the Cross and vocalist/drummer Infernal Commando Necromansy, drawing primary influence from the raw South American extreme metal of Sarcófago, Vulcano, and early Sepultura. The band released their debut album Black Death Commando in September 2014, a five-track record steeped in themes of Satanism and blasphemy.

Morbus Sacer plays a raw, uncompromising hybrid of black and death metal rooted in the South American underground tradition. Their 2017 demo, Demo MMXIII, was released on cassette through Aurora Australis and delivers four tracks — Iron Cleaves, Obliteration, Salve of the Enervated, and Non Serviam — with a crude, hostile production that suits the material.
