Once a member of the Swamp Men of the Savage Land, a tropical jungle hidden away in the frozen wastes of Antarctica, Barbarus was one of several of his people who were artificially mutated through technological means by the self-styled mutant master of magnetism, Magneto, so as to grant them superhuman powers. On Magneto's behalf, the Mutates subsequently battled Ka-Zar, the Lord of the Savage Land, and his allies in the team of superhuman mutant adventurers known as the X-Men. After the destruction of Magneto's machines by the X-Man named Marvel Girl, the Mutates returned to their original non-superhuman states.

However, the Mutates later regained their powers thanks to the effects of the technology that changed them, causing them to regain their superhuman abilities should they ever lose them. Renaming themselves the Beast Brood, the Mutates proceeded to capture scientists in the hope of forcing them to mutate other Savage Land natives into superhuman beings. The costumed adventurers known as the Avengers and the Norse goddess Sif came searching for the scientists and defeated the Beast Brood, delivering them to legal authorities in Chile, the nearest nation to the Savage Land.

Barbarus is an artificially mutated being who possesses superhuman strength in all four of his arms that allow him to lift at least 30 tons. The upper limits of his strength have yet to be ascertained. Barbarus also possesses enhanced durability, endurance, and a speed that belies his massive frame.
