The Fighter of TMNT is a mammoth, efficient nation, ruled by Splinter with an even hand, and notable for its teetotalling pirates, barren, inhospitable landscape, and smutty television. The hard-nosed, devout population of 6.806 billion TMNTians are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The large, corrupt, moralistic government juggles the competing demands of Education, Industry, and Administration. It meets to discuss matters of state in the capital city of Sewers. The average income tax rate is 51.6%, and even higher for the wealthy.

The frighteningly efficient TMNTian economy, worth 657 trillion deniers a year, is quite specialized and led by the Information Technology industry, with significant contributions from Uranium Mining, Book Publishing, and Door-to-door Insurance Sales. Black market activity is rampant. State-owned companies are reasonably common. Average income is 96,669 deniers, and evenly distributed, with the richest citizens earning only 2.4 times as much as the poorest.

Law schools are hurrying to teach the "prank defense" to their students, increasing numbers of children in TMNT have different eye and hair color to their supposed fathers, barbed wire entanglements and guard towers surround the Sewers Natural History Museum, and increasing inclusiveness is a sign of the times. Crime is moderate, perhaps because of the country's complete lack of prisons. TMNT's national animal is the turtle, which teeters on the brink of extinction due to heavy metals seepage into national waterways, and its national religion is Pizza.

TMNT is ranked 30,077^th in the world and 3^rd in Square Enix for Most Cultured, scoring 79 on the Snufflebottom-Wiggendum Pentatonic Scale.
