Bullet Bill ain't necessarily a bad bloke, but like all bullets he was made to kill, maim and destroy- so love will remain forever out of reach of his stubbly little arms.
So Bill launches himself into his work, flying back and forth across the level in hopes of making a connection and feeling that certain spark that will lead to explosive revelation.
But, as this Shmorlock Comics strip shows, Bill will never find true love, nor will he ever discover his true reason for being, because he's just an extra in a video game about Mario's life.
