The Pied Piper of T-Rex is a titanic, orderly nation, ruled by Rex Middlefinger with an iron fist, and notable for its enslaved workforce, flagrant waste-dumping, and irreverence towards religion. The hard-nosed, hard-working, cynical, humorless population of 11.6 billion T-Rexians are rabid consumers, partly through choice and partly because the government tells them to and dissenters tend to vanish from their homes at night.

The relatively small, corrupt, well-organized government is primarily concerned with Defense, although Industry is also considered important, while Social Policy and Environment receive no funds. It meets to discuss matters of state in the capital city of Theropodus. Citizens pay a flat income tax of 31.3%.

The frighteningly efficient T-Rexian economy, worth a remarkable 1,760 trillion $$s a year, is broadly diversified and dominated by the Arms Manufacturing industry, with significant contributions from Retail, Gambling, and Uranium Mining. Black market activity is rampant. Average income is an impressive 151,768 $$s, but there is a vast disparity between incomes, with the richest 10% of citizens earning 1,205,853 per year while the poor average 4,580, a ratio of 263 to 1.

Children have only the most basic of education, extraordinary rendition is nothing out of the ordinary, toast never burns but always has a weird chemical taste, and sales of superhero insurance have skyrocketed after the government abandoned the police in favor of vigilantes. Crime is all-pervasive, probably because of the absence of a police force. T-Rex's national animal is the me, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Roman Catholicism.

T-Rex is ranked 214,535^th in the world and 16^th in BLITZKRIEG for Most Scientifically Advanced, scoring 43.13 on the Kurzweil Singularity Index.
