Throughout human history, warriors have used symbols to gain power and protection, which makes certain warrior symbols very popular as tattoos.
From the Aztec symbol for the sun to striking, stylized eagles, warrior tattoo meanings are often linked to a sense of invincible power and bravery. War paint and traditional Mauri pieces remain popular for that reason.
Weapon tattoos meaning potency and power are also rising in popularity. Celtic shields, lethal swords, and even modern rifles are all a way to warn the world that you are dangerous.
