Vampire Viper

Markus Sarkello, better known as Vampire Viper, was a MESH and the last surviving member of the Viper Legion. He was the primary antagonist of Issues #1-#9 of The PGXD Adventures.

History
Markus Sarkello was born on June 18, 1981, to a family of poor merchants living in the slums of eastern Metello, a small city in the eastern Saugerdese Empire. As a child, he often had to steal food from local restaurants to feed his family. When he was six years old, his father was killed in a street fight, leaving his mother to raise the three children on her own.

Metello was a city ridden with gangs and organized crime. The most violent of these gangs was The Vipers, a heavily organized criminal organization that was known for its extremely gruesome homicides, in which the gang marked their victims by biting into their neck and draining their blood.

Sarkello was inducted into the gang at the age of twelve, after unknowingly murdering a member of a rival gang. His member number was #62.

On April 27, 1999, a rival gang, known as the Masked Messiahs, bombed the gang's main headquarters in downtown Metello, killing 243 of the 244 members. The sole surviving member was Markus Sarkello. He was severely injured and required Mechanical Enhancement to survive. After the bombing, Sarkello donned the mantle Vampire Viper and began seeking vengeance on members of the Masked Messiahs.

Over the next two years, he killed 43 members of the Masked Messiahs.

Death
On the night of Janurary 6, 2009, Entity 303 finally decided to execute his plan. While Sarkello was sleeping, he stole his dagger from the Burial Box and attempted to slit his throat. However, Sarkello woke up before 303 could strike, resulting in a long brawl occurring between the two. During the fight, Sarkello bit into 303's neck, injecting him with Viper Venom, which caused part of his CMC to malfunction, temporarily stunning him. While 303 was stunned, Sarkello attempted to steal the dagger from his hands. Ultimately, though, Sarkello was overpowered by 303, who broke his arm and stabbed him through the heart with his own dagger, trapping his soul inside of the blade.

Viper: Rebirth
In the limited series Viper: Rebirth, Sarkello is resurrected as Nega Viper, an extremely powerful entity who is able to manipulate Soul Energy to perform magic.
