Kingpin

The Kingpin is a major Marvel Comics villain that originated in the Spider-Man comics and media. He has since then gone on to be a major enemy of Daredevil as well as a recurring villain for the Punisher. In recent years he has been revised as being more of Daredevil's enemy rather than Spider-Man's.

Origin
Growing up as Wilson Fisk the Kingpin grew up in poverty and was tormented by his classmates for being overweight. Tired of being bullied, he began to train himself in physical combat. When he gained a powerful physique, he forced his former tormentors into joining his gang, and thus, his desire for absolute control began. Later on in life, he met a crime boss named Don Rigoletto. At first, he fostered an alliance with Rigoletto, but then, betrayed him and murdered him. The Kingpin, then, took over Rigoletto's gang, and took Rigoletto's place as the most powerful crime boss in New York City. He would later join the international terrorist syndicate HYDRA and become a prominent figure as one of their heads of operations.

The Daredevil grudge
Although Kingpin started off as a Spider-Man villain, it's thanks to Frank Miller that Wilson Fisk is now the arch-nemesis of the Man Without Fear. It was in Miller's storyline, Born Again, that the Kingpin earned this title; using information from a drug addicted, porn starring Karen Page, Kingpin slowly began to ruin Matt Murdock's life, destroying his home, lose his sanity and leaving him a derelict. It was only thanks to his mother that Matt regained his confidence to fight again, and the Kingpin was exposed as a criminal, being given a taste of ironic justice.

Trivia
Although The Kingpin appears overweight this is actually muscle, making him an individual who, while not superhumanly strong, is at peak human physical condition.
