What is scars tattoos fma?

Scars tattoos in FMA refer to the tattoos that are engraved on the bodies of certain characters, such as Scar and the Homunculi. These tattoos are a form of alchemy, known as 'alchemy arrays', which allow them to perform powerful alchemical techniques. Scar himself bears the 'deconstruction and reconstruction' arrays on each of his arms, which he uses to deconstruct and reconstruct matter on a molecular level. The Homunculi, on the other hand, bear a different array on each of their bodies, which grants them unique abilities. For instance, Lust's array grants her the power to extend her fingernails into sharp blades, while Envy's array allows him to shape shift into any form he desires. These tattoos are an integral part of the FMA universe and serve as a powerful symbol of the alchemic power and talent of their bearers.
