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 a fictional character and one of the main antagonists of the DC series. He is one of Batman's oldest enemies and arch-nemesis throughout his crime-fighting career and responsible for some of the most horrendous and tragic moments in Batman's life, cultivating in an extremely long and brutal battle where there seems to be no end in sight. An insanely homicidal super-villain with no powers beyond his capacity for incredible violence and creating deadly mayhem, Joker's white skin, green hair, and blood-red lips belie the chaotic nature underlying his cartoonish appearance.

Leaving a trail of death and destruction wherever he goes, Joker's only motive in life is to create as much mindless violence and chaos as possible and enjoy in a game of cat and mouse with his nemesis, Batman, whom he disturbingly views as both his greatest enemy and friend. He frequently concocts complex and elaborate plans to entrap Batman and destroy Gotham City, often resulting in the deaths of hundreds and thousands of innocent individuals.

Seeking nothing but pure destruction and anarchy, Joker also used Black Mask's likeness, gang, and resources to send out a massive crime wave throughout Gotham while hiring eight of the world's most deadly assassins to take out the Dark Knight himself, holding a particular vendetta against the hero. With connections all over Gotham's institutions and infrastructure, the Joker begins a deadly and sick game of cat and mouse with Batman as he begins to realize that the Dark Knight is similar to himself and might just be the perfect rival he needs to complement his sadistic appetites.

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

Abilities and Traits
During combat, Joker employs his lethal laughing gas, a revolver handgun, and his joy buzzer as special attacks. He uses his impressive hand-to-hand abilities to punch, slap, kick, and poke out eyes. During stealth missions where Joker must dispose of his enemies, he can use a pair of glasses with swirly circles in the lenses to see through walls and identify others behind. Another weapon he has is remote-controlled chattering teeth that carry explosives.
