10 Supervillains Who Made Other Supervillains

Before she was the hammer-hurling, Mistah J-lovin' Harley Quinn, Harleen Quinzel was a criminal psychiatrist. She wasn't just good at her job. She was too good. She found it so easy to psychoanalyse her subjects that she fought for a transfer to Arkham Asylum, believing the inmates would provide a challenge.

When she was assigned as the Joker's personal counsellor, it wasn't long before the grinning menace used his wicked charm to seduce her. When he doused her in the same chemicals that turned him into the Joker, he dubbed her as his new partner-in-crime, Harley Quinn.

Even though Joker promised her the world, it wasn't long before he tired of her. After she and the Clown Prince of Crime parted ways, Harley became more of an anti-hero than a supervillain.

However, she has DEFINITELY spent more time working against the law than for it since she has take part in countless crime sprees, killed innocent people, performed dozens of missions with the Suicide Squad, and personally fought against many superheroes, especially Batman.

Even though the Joker has devised countless traps, weapons, and schemes over the years, Harley Quinn is unmistakably his most defining creation.
