From Madrid, Spain, Marcos started tattooing in 2012. Influenced by the punk rock underground scene, Marcos began drawing tattoos, album covers, and posters. At the age of 17, he built a handmade tattoo machine and tattooed his own leg for the first time.

A few years later, he moved to London in search of an apprenticeship and shortly after began tattooing professionally.

Later, he relocated to Berlin, Germany, where he has worked with a solid and loyal clientele for the past 11 years.

Marcos co-owned two significant shops in Berlin: "Out of Step Tattoo Parlour" & "Stay Free Tattoo," leaving a lasting impression on thousands of German customers. During those years, he undertook painting commissions for tattoo books, participated in conventions, and became an integral part of the German tattoo scene.
