Marcus was born on the planet Mandalore, home of the fierce warrior culture known as the Mandalorians. From a young age, he showed a keen interest in the Mandalorian ways and trained tirelessly to become a skilled warrior. As he grew older, Marcus became disillusioned with Mandalore's leadership and how they used their warrior culture for nefarious purposes. He left his home planet to become a bounty hunter, using his skills to help those in need and right wrongs throughout the galaxy. He took on the name "The Mandalorian" to honor his heritage while distancing himself from the actions of the Mandalore government. He quickly gained a reputation as a skilled and honorable bounty hunter, always true to his code of protecting the innocent and serving justice.
