Mach's origins trace back to a planet nestled near the Krall system in the vast galaxy. He began his journey as a soldier, thrust into the tumultuous war against the relentless Krall, whose insatiable hunger for domination knew no bounds. In the crucible of the final battle, he suffered grave injuries that should have claimed his life.

A team of medical droids intervened, salvaging his existence but at a staggering cost. Most of his flesh and organs were lost, replaced by mechanical components, rendering him a cyborg, half-human and half-machine. From that moment, Mach's existence shifted, propelling him into the forefront of the battle for the liberation of countless systems.

Mach was a formidable warrior, a force to be reckoned with on the battlefield. However, beyond the ferocity of combat, he also possessed the heart of a compassionate mentor. As the leader of the AIS rebel group, he was known for his unyielding resolve and unwavering commitment to the cause of freedom.

A skilled mechanic, he lent his talents to the rebellion, constructing devices and weaponry that would prove invaluable in their fight. Amid the chaos of war, Mach found solace in the bonds he shared with his daughter, even as the specter of the Krall loomed ominously over their lives.

For Mach, the belief that violence was the only means to quell the Krall threat was an unshakable credo, encapsulated in his mantra, "kill or be killed." While it fueled his determination, it also created discord within his group. His gruff demeanor and the sparing nature of his words contributed to his enigmatic aura.

Symbolized by a red circle with a white X inside, Mach's actions were considered criminal by the authorities, yet his true secret was the fact that he was a cyborg, uncertain of how others would react to this revelation. His famous quote, "fighting for freedom is the most important thing in the universe," encapsulated his unwavering commitment to the cause.

Mach's dream was a simple yet monumental one—to witness the galaxy free from the oppressive grip of the Krall. His journey was a tapestry woven with threads of violence and betrayal, but his resilience remained unbroken, and he continued to chase his dreams.
