A death metal act rooted in the brutal sound of the '90s Brazilian scene, Mortal Eyes delivered the demo "Extreme Visions" in 2005, a five-track effort blending crushing heaviness with traces of thrash aggression. Tracks like "Mirror of Darkness" and "Angel Burner" reflect a straightforward, unpolished approach to old-school death metal.

Founded by Gustavo Camargo and Flávio Diniz, Mortal Ways weaves science fiction and extraterrestrial mythology into death metal rooted in the traditions of Morbid Angel, Hypocrisy, and Deicide. Their 2020 self-titled debut and the 2021 EP "Enslavement Pandemic" — a four-track concept piece drawing from biology and astronomy — showcase a band committed to thematic storytelling within a crushing sonic framework.

Formed in Uberlândia by guitarist Gabriel Tino and bassist Macarrão, Morterror plays straightforward death metal rooted in the genre's fundamentals while drawing on a wide range of metal influences. Their 2021 EP Sertão da Maldição is a four-song cycle built around local horror folklore — specifically the curse-laden deaths of a remote interior settlement called Sertão da Farinha Velha — with tracks like "Sangue Podre" and "Boi Fumaça" translating those dark regional legends into crushing riffs.

Morthur is a power trio from Erechim, Rio Grande do Sul, featuring guitarist and vocalist Jeferson Casagrande alongside drummer André Cândido and bassist Fabricio "Ganso" Macali, blending old-school and modern death metal influences into a dense, riff-driven sound.

Morthure emerged from Curitiba's underground scene with a sound anchored in the crossover zone between thrash and death metal, carrying the weight of the band's earlier existence as Overlook. Their debut album Where Everything Shall Die, an eleven-track record released independently, established their appetite for punishing riff structures and aggressive tempos.

Their music explores themes of death, anti-religion, and occultism.

Mortiferik is a one-man funeral doom project built around the bleakest end of the death/doom spectrum, drawing on the suffocating pace and crushing despair of the genre's key forebears. The project released the "Empire of Sadness Returns" EP and appeared on the "Doomed Serenades" Brazilian doom compilation, marking it as a committed voice in the country's underground doom scene.
