My name is Big-Die Unknown-Man. A moniker born from the shadows, forged in the fires of war. It all started in the desolate wastelands of Outer Heaven, where survival meant embracing the darkness within.

Raised amidst the chaos of conflict, I learned early on that in this world, power was the only currency that mattered. With each battle, I honed my skills, mastering the art of stealth and subterfuge.

But it was a fateful encounter with a legendary soldier that changed everything. Snake, they called him. A man of unparalleled skill and determination. In our clash, I saw a reflection of myself, a glimpse of what I could become.

Driven by a thirst for knowledge and a desire to surpass my limits, I delved into the depths of science and technology, augmenting my body with cybernetic enhancements. With each upgrade, I became more than human, a living weapon forged in the crucible of war.

But power comes at a price. As I ascended the ranks, I found myself caught in a web of intrigue and betrayal, manipulated by unseen forces with their own agendas.

Now, as the shadows of war loom once more, I stand at the crossroads of destiny, a pawn in a game played by gods and monsters. But I refuse to be a mere footnote in history. I am Big-Die Unknown-Man, and my legend will echo through the ages.
