Joker

**Jack Napier** (ジャック・ネイピアー, *Jakku Neipiā*) a former comedian, a petty thief, and a broken family man, also known as an insanely super-villain named **Joker** (ジョーカー, *Jōkā*) was one of Batman's oldest enemies and deadliest arch-enemy who was ruthless, cunning and extremely dangerous throughout his crime-fighting career. The Clown Prince of Crime had no pity for anyone he forced to take part in his nefarious schemes either by blackmail or deception and was especially unkind to his henchgirl and lover Harley Quinn, such as manipulating her to amuse himself.

With no super-powers beyond his capacity for incredible violence and destruction, Joker prides himself on being the one villain in Batman's extensive rouges gallery who shares a unique connection to the hero, seeing the Dark Knight as not only his greatest enemy, but friend as well. As intelligent as he is violent, Joker has formulated, as well as tried, every despicable tricks and countless plans to destroy and take over Gotham City, leading to countless catastrophic consequences over the years.

One of Batman's oldest enemies and his main nemesis, Joker has haunted Batman's life for years, often being responsible for some of the most tragic moments of his life. Seeking to break Batman's moral code and ruin his life, both emotionally and physically, as well as create as much destruction and chaos as possible, Joker's unpredictable nature make his plans to destroy Gotham complex and difficult to thwart.

Since his emergence within Gotham, Joker has seized complete control of the city's criminal underworld, gaining thousands of followers, overseeing a majority of its crimes and operations, making a profit, and quickly became one of the city's most infamous criminals. With his chaotic actions serving as the catalyst for massive plans that constantly target Gotham City and Batman himself, the villain was always plotting and contriving situations that put the Dark Knight in a position that threatens his moral code of never taking a life, no matter how evil. He also escaped death several times after his defeats with Batman, until his final eventual death many years later.

"*All it takes is one, rotten day, to transform a normal man, into a real freak like me... It'd be a lot more funny if, well in may case, if the rotten day with a chemical bath, weren't so pathetic.... But, then again, why should I care? When I'm just gonna laugh it all anyway!"*"
