Immortal Zero

Aiden had only been able stagger two steps because of his injured leg when a couple of crazies fell upon him. He shot one in the face, but the other one batted his gun aside as the crazy sank his teeth deep into the side of Aiden's neck. Aiden screamed and forced the man off of him far enough so that he could bring his gun hand up and shoot the mad man in the chest. Aiden looked back at limo 5 and saw two agents gently putting the president into the vehicles back seat.
Dragging his leg and using his left hand to stem the flow of blood from his bleeding neck, Aiden tried to make his way to limo 5. But half dozen crazies cut him off. Aiden fired his gun at the crowd, watching with satisfaction as all six went down and stayed down.
Aiden got a little closer to the limo, watching as his agents piled in and waived for him to hurry. Aiden had just reached the spot where he had just killed six crazies when one of those he shot in the chest sat up, grabbed his bad leg and bit into it as if it was a cheeseburger.
Aiden screamed as he felt his flesh tear away from the bone as the woman, who should have been dead, began chewing on his torn flesh with gusto. Aiden cursed, put his pistol to her skull and blew half her head away. "Get the President out of here!" Aiden yelled between clenched teeth as the pain became almost unbearable.
