Neurotóxico brought a technically ambitious edge to the Brasília extreme metal scene, blending aggressive thrash foundations with death metal dissonance on their 2015 debut demo Web of Terror. The nine-track demo was produced by Zé Misanthrope at Less Than Zero Studio and featured a twin-guitar attack from Guilherme Lee and Pedro Azoth underpinning the caustic vocals of Gabriel Mosna.

Formed in Uberlândia with the explicit goal of fusing New York hardcore aggression with thrash metal heaviness, No Defeat released the EP M em M in 2010 and the full-length Escolhas Que Precedem a Conquista in 2012. Vocalist Michel "Padero" anchored their politically charged output, which drew on crossover forebears while addressing social and political themes rooted in Brazilian reality.

No Guerra is an Argentine thrash metal and metalcore band whose album titles — Ahonikenk (2010), Choiols (2012), Weychan (2014), and Traumatica (2024) — draw on the indigenous languages and cultures of Patagonia, including Mapuche and Tehuelche words. After a decade-long gap, the band returned in 2024 with Traumatica, their fourth studio album.

The project of guitarist and vocalist Tiago Torres, a veteran of the Brazilian scene through his work with Mad Dragzter, No More Death channels the fury of Metallica, Slayer, and early Sepultura into a decidedly spiritual framework, with lyrics drawn from the Book of Revelation. Their debut album "The Death is Dead," released in 2025 on Roxx Records and co-produced with Demis Kohler, delivers eight relentless tracks that treat thrash as a vehicle for Christian apocalyptic storytelling.

NoWrong deliver punishing thrash metal with a blunt fixation on politics, social inequality, and modern urban violence, channeling those themes across the 13 tracks of their 2014 debut Prognostic of a Great Disaster. The record leans heavily on classic Bay Area and Teutonic influences, keeping the riffs fast and the production raw without losing coherence.

Nucflash is a thrash metal band from Buenos Aires, Argentina, that emerged from an earlier project called Warfare before settling on their current lineup and name. They released the EP Spreading the Virus in 2011 and The Purifying Fire in 2017, and shared the stage with German thrash veterans Kreator in 2013.

Nucleador came out of Sergipe playing uncompromising crossover thrash in the mold of the 1980s hardcore and thrash collision, recording their first EP within six months of forming despite none of the members having prior experience in the genre. They've built a steady catalog since, including the 2014 EP United by the Toxic and the 2021 full-length Back From the Dead, earning a spot at São Paulo's Night of Living Thrashers festival early in their career.

Nuclear Screams traffic in a dense blend of death, thrash, speed, and melodic death metal that leans heavily on aggression without abandoning hooks. Their debut EP A Path to Endless Days arrived in November 2021, and the full-length Human Frailties followed in 2025, both recorded in Minas Gerais and showcasing a band comfortable moving between brutal riffing and more atmospheric passages.

Nuclear Trauma is a solo crossover thrash project born during the pandemic, built around raw and unfiltered riffing with lyrical content focused entirely on warfare and armed conflict. Early recordings including the ISMO demo, Religious War, and Remains of War establish a stripped-down sound in the tradition of classic American crossover, with no frills and no concessions.
