A man who is extremely suave, much like a Don Juan. More romantic connotation than playboy. Called a ladykiller due to his ability to shoot an arrow of love through a lady's heart.

Billy Bob: "Dja see the heads turn when he walked in the room?"

Alfred The Mankiller 

In a distopian future; Captain ALM grows bored of hacking computers and breaking mainframes... he requires something more. Something... better. Alfred developed a love for snapping human spines after his first victim, Henry Ozolins.

Obviously he requires a new name. He becomes Alfred The Mankiller.

This interpretation of the Captain is a brutal killing machine who knows no fear.

Henry Ozolins: Holy shit it’s Alfred The Mankiller!

Alfred The Mankiller: There seems to be a break - (snaps Ozolins neck) - in the mainframe
