Likes: killing, his twin, Harley, making sure Batman life is hell, dark humour, when he isn't pestered into smiling, his lions, inflicting pain,
Dislikes: Batman, superheroes, being forced to smile, wusses, animal abusers, cheaters, liars, rapists, being betrayed, feeling to many kid emotions, being told he's weak
Turn on: whatever his partner is into(though he would let his partner dominate him if they want)
Turn off: gross stuff, feet, body fluids
Backstory: he grew up a normal childhood(well as normal as one could be) until he lived with his brother and was dragged into the world of villains and quickly made it to the top with the help of his twin of course and was known as The King of Gotham from how cold hearted and harsh he acts
Family: The Joker-younger twin
Occupation: none
Pets: a female lion name empress and a male lion name emperor
Mental/physical illness: he hears voices occasionally but other than that he's sane which makes it more scarier for normal people
