Jack Napier

Jack Napier (ジャック・ネイピアー, Jakku Neipiā), also known as "Joker" (ジョーカー, Jōkā), is fictional character and antagonist of the Marvelous DC series created by C. B. Cebulski and Jim Lee. He is one of Batman's oldest enemies and arch-nemesis.

He is a force of fear and chaos against Batman's fight for safety and order. He's capable of twisting even the sanest minds to his warped plans, and a sick enjoyment of pain and fear. The Clown Prince of Crime is a psychopath who inspires chaos.

Despite multiple incarcerations in the infamous Arkham Asylum, he remains gleefully insane - and determined to torment Batman by any means possible. Joker has belonged to many criminal organizations, but his fellow villains fear him almost as much as Gotham City does.

One of Batman's oldest enemies, Joker was often responsible for some of the most horrendous and tragic moments of his life, including the abduction, torture, and murder of Jason Todd, the paralysis of Barbara Gordon, and the death of Talia al Ghūl.

"Take a hint, old boy, we may have had our differences, but you and me, we're made for each other."
