Brazil was a large country in South America. Its capital was Brasilia.
During the 2012 Apocalypse, Rio de Janeiro was hit by a massive earthquake, which led to the fall of the Christ the Redeemer, the famous statue overlooking the city as the earthquake wrecked havoc across the country, killing millions. The remains of Brazil were swept by a megatsunami of 1500 meters during the Worldwide Flooding.
After the apocalypse ended, Brazil was submerged underwater, left with extreme damage, and is rendered uninhabitable.
