An internet fanclub for the fictional character Tetsutetsu Tetsutetsu that is characterized by passionate fans, a lot of inside jokes, and pure chaos. Members of Tetsu Nation have an unabashed and ever-growing love for our lord and savior Tetsutetsu Tetsutetsu, and they usually have some sort of mental illness too.

Tetsu Nation was formed to spite those who claim that Tetsutetsu is just "ugly, silver Kirishima," and this ultimately evolved into aggressive simping, too much brainrot, and a LOT of opinions.

Members of Tetsu Nation are also referred to as Iron Nuggets, Spinaches, The Iron Men and Women, Tetsu Petsus, and the Tetsu Army. Tetsutetsu himself has been referred to as Tetsu, Iron Boy, Steel Boy, Real Steel, Our Lord and Savior Tetsutetsu Tetsutetsu, Kirishima but Better, and the Best Part of the Series.
