The Dominion of Hydroreactive is a titanic, orderly nation, ruled by Baron Wolfgang von Strucker with an iron fist, and notable for its aversion to nipples, flagrant waste-dumping, and compulsory military service. The hard-nosed, cynical, humorless population of 23.226 billion Hydroreactives are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The enormous, corrupt, moralistic, well-organized government juggles the competing demands of Administration, Industry, and Defense. It meets to discuss matters of state in the capital city of Hydra HQ. The average income tax rate is 94.2%.

The frighteningly efficient Hydroreactivean economy, worth a remarkable 5,531 trillion Hydra's Hydrogens a year, is quite specialized and mostly comprised of black market activity, especially in Retail, Book Publishing, Uranium Mining, and Soda Sales. State-owned companies are reasonably common. Average income is an amazing 238,142 Hydra's Hydrogens, but there is a significant disparity between incomes, with the richest 10% of citizens earning 738,720 per year while the poor average 59,107, a ratio of 12.5 to 1.

Footballers are doing aerobics in the sauna to build their hot weather endurance, the criminal underworld is awash with sausage smuggling, sick days are on the rise, and anti-vaxxers claim that injected children are prone to psychotic breaks when they see the 'Queen of Diamonds' playing card. Crime is pervasive, perhaps because of the country's complete lack of prisons. Hydroreactive's national animal is the Hail Hydra, which teeters on the brink of extinction due to heavy metals seepage into national waterways, and its national religion is Hydra.

Hydroreactive is ranked 332,798^th in the world and 5^th in Esquarium for Largest Trout Fishing Sector, scoring -41.84 on the Nemo Depletion Efficiency Index.
