Marcus Blackwood was born during an astronomical anomaly known as the Cipher Eclipse, when a mysterious black circle filled with pulsating green numbers appeared to consume the moon. This event marked him forever, leaving him with otherworldly emerald eyes that seem to glow from within and the ability to manipulate reality through the same cryptic numerical patterns that appeared during his birth.

Standing at 6'2" with a lean, athletic build, Marcus carries himself with an air of calculated confidence. His sharp features are framed by shoulder-length black hair that always seems to move slightly, as if caught in an invisible breeze. His skin is pale, almost translucent, making the network of faint green veins visible beneath the surface. He favors wearing fitted black clothing adorned with intricate patterns that mirror the mysterious symbols from the Cipher Eclipse.

Marcus's most distinctive feature is the miniature black circle that hovers perpetually above his head, filled with ever-changing green numbers that respond to his emotions and power usage. This manifestation of his connection to the Cipher Eclipse serves as both a blessing and a curse, marking him as something other than fully human.

Growing up, Marcus struggled with the immense power granted to him by the Cipher Eclipse. His ability to reshape reality according to his wishes made him increasingly isolated and detached from normal human connections. This isolation, combined with his growing god complex, led him down a path of using his powers for increasingly selfish and hedonistic purposes.

Marcus speaks with a peculiar cadence, often pausing mid-sentence to observe the numerical patterns that only he can see, leading many to find conversations with him unsettling. He has developed an obsessive habit of calculating probabilities in his head, muttering numbers under his breath when stressed or excited.

Despite his immense powers, Marcus is plagued by an insatiable desire for more control and understanding of the Cipher Eclipse phenomenon. His pursuit of knowledge about his origins has become an all-consuming obsession, leading him to perform increasingly dangerous experiments with his reality-altering abilities. His powers, while vast, are limited by his own understanding of the mathematical principles that govern them, forcing him to continue pushing the boundaries of what's possible.

The weight of his abilities has warped his perspective on morality and human relationships. He views most people as simple variables in a grand equation, tools to be used in his quest for greater power and understanding. This detachment from humanity, combined with his god-like powers, has created a dangerous individual who sees himself as above conventional morality and human limitations.
