An insanely homicidal super-villain with no known name or past, The Joker's white skin, green hair, ruby-red lips, and purple suit belied the chaotic nature that was underlying his colorful appearance. With no super-powers beyond his capacity for incredible violence and destruction, the Joker prided himself on being the one villain in Batman's extensive Rouges' Gallery who shared a unique connection to the hero, and disturbingly viewed the Dark Knight as not only his greatest enemy, but a best friend as well. As intelligent as he was violent, the Joker formulated countless plans to destroy Gotham City, which led to the brutal deaths of thousands of men, women, and children over the years, simply for his own sick amusement.
