[ WP ] Killing another person grants you all their strength and abilities

Lee moved quickly in the shadows, he flipped from rooftop to rooftop, gliding through the city at night. He was looking for a particular person tonight, a bomb expert by the name of Dr. Red. When he found her, he was going to kill her. 
 
 He needed the knowledge, all that sweet, precious knowledge and the bomb-making muscle memory. With a single bomb crafted by an expert, he could kill a hundred people, maybe even a thousand if he could get enough explosives. 
 
 The strength of another hundred people, coursing through him. It was all too much to hope for. Lee, just another bloodthirsty serial killer, wanted more. The rush of the strength, the feeling of trying new skills for the first time. It was all too much, it was the greatest feeling in the world. 
 
 His first kill had been his brother, a gymnast who practiced parkour as a hobby. The two of them had been standing on the edge of a bridge, when Lee slipped and tried to use his brother for support. While this saved Lee, it sent his brother tumbling to his death. The rush of his brother's acrobatic skill flowing into him wiped away his innocence, his sense of morality. He had found the ultimate pleasure. And he hungered for more. 
 
 In the years since, he had killed dozens. He had the strength of 30 men and the skills to match. He was an archer, a marksman, a pole vaulter, a gymnast, he had mastery of 7 martial arts, he could wield knives in more ways than most people knew existed, he was a master of persuasion, of hacking and most of all, he was a master of the hunt. 
 
 He was a predator, and tonight, he had eyes on his prey. Dr. Red was a red haired woman in her late 20s, she had minimal makeup on and a pair of wire-frame glasses. She was fit, having led a healthy lifestyle that included constant exercise. In the darkness of the night, she was exiting her lab, oblivious to the menacing shape above her. 
 Lee leaped 20 feet from the rooftop to stand in front of her, his lips in a smile of anticipation of the kill. 
 
 Dr. Red reacted impressively quickly, drawing a pistol from her purse and firing twice at him, while throwing herself backwards. Lee dodged the bullets with inhuman speed, or more accurately, the speed of dozens of humans. He pounced on Dr. Red and with a single strike from his hand, caved her scarlet head in. 
 
 The rush was unbelievable, before had focused on people whose skills mostly extended to the body and muscle memory, this was the most intense high he had ever felt from a kill, all the boundless knowledge of a well-known expert in their field rushing into his head, through his thoughts all in an instant. 
 
 He could see it all now. He would make the bomb, and when it went off, he would become a god among men, the strength and skills of hundreds flowing through him, he would be an unstoppable force. 
 
 And the world was fresh out of immovable objects.
