Megadriver is one of the originators of the "game metal" subgenre, translating the soundtracks of classic arcade and console games — particularly the Sega Mega Drive library — into full-throttle heavy and power metal arrangements. Over nine studio albums and more than 150 arranged tracks, the project has appeared at festivals including Video Games Live and MAGFest, building a global following among metal fans with a love for retro gaming.

Monte Cerrado launched with a self-titled two-track EP in March 2022, featuring the songs "Lose our Humanity" and "Fake" — an immediate showcase of their melodic power metal approach with an emphasis on strong hooks and soaring arrangements.

The solo project of Cris Oliveira, Nestor Durruti channels classic heavy and power metal through an explicitly anarchist lens, naming the band after the Spanish anarchist icon Buenaventura Durruti. The 2020 debut Passos includes a cover of Judas Priest's 'Electric Eye' alongside original material steeped in libertarian politics and melodic metal craft.

Newsonic channel the progressive grandeur of Dream Theater and Symphony X through a distinctly Brazilian lens, crafting dense, emotionally driven metal that occasionally drifts into symphonic territory. Their 2019 debut Vorax is an 11-track album tackling subjects ranging from social media dependency and mental health to mythology and natural disasters, anchored by powerful melodic vocals and a tightly constructed band sound. The group has been active since 2011 and built their reputation as one of Rio's stronger underground progressive metal outfits.

A melodically ambitious power metal band fronted by vocalist Andrea Pietro, Ocean Soul drew on the European power metal tradition with a distinctly Brazilian warmth.

Omni Gear emerged in 2016 from the ashes of Rebel Machine, a heavy metal act the same members had been running since 2005, bringing a harder power metal focus to the new project.

P.A.N.D.E.M.I.A. is a heavy and power metal band from Buenos Aires with roots stretching back to 1997, making them one of the longer-running acts in Argentina's traditional metal underground. The acronym-based name — a stylistic choice common in Argentine metal bands of that era who wanted to signal both seriousness and a kind of programmatic identity — reflects the band's commitment to a muscular, melodically driven heavy metal sound that draws on European power metal traditions while grounding itself in the distinctly Argentine approach to the genre pioneered by acts like Rata Blanca and Horcas. Buenos Aires has always been the nerve center of Argentine metal, and a band surviving from 1997 into the present has navigated through every shift the local scene has undergone: the economic crises of the early 2000s that devastated the music industry, the gradual recovery of live music venues through the 2010s, and the rise of streaming platforms that opened new avenues for underground bands to reach audiences beyond their immediate geography. Power metal as a form suits the Argentine sensibility particularly well — the genre's emphasis on soaring vocal melodies, technical guitar work, and epic themes maps neatly onto a scene that has always prized musicianship and emotional intensity over pure brutality. P.A.N.D.E.M.I.A. represents the resilient core of Buenos Aires's traditional metal scene: bands that have never chased trends, never broken up for commercial reasons, and continue to exist on the strength of genuine conviction and a loyal regional following.

Pagan Throne fuses pagan black metal aggression with epic power metal sweep, centering their lyrics on ancient civilizations, mythology, and battles across a catalog that includes "Swords of Blood" (2015) and "Land of the Greeks" (2023). The band carries a lineage stretching back to the late 1990s under an earlier name, giving their sound a well-honed sense of bombast and conviction.
