Bio:

Heath was born of the Joker, Gotham's greatest and most feared villian, and Bruce Wayne aka The Batman, the Hero of Gotham.

A truely strange child, Heath was discovered at the age of three to be somewhat of a genius. He was much more advanced mentally than children his age, he was able to form intelligent and coherent senteces, do grade-level math and could create small bombs, only that when set off, created a small poof of smoke.

Of course, being that his mother is in fact insane and mental diseases are hereditary, Heath soon developed a slight schyzophrenia, ADHD and slight OCD (but doesnt effect him terribly) and of course a very violent mind.

Heath is a dangerous individual, but in somewhat of a more stable mental state than his mother. Becoming a criminal and following in his footsteps, Heath put Gotham into a greater sense of fear at the mere age of 15, when his first crime: the kidnapping and killing of Gotham's mayor and DA. Soon after, Heath already clad in a Joker style of make-up, set out to cause more trouble.

To this date, he has yet to find a worthy hero to call his nemesis and has had to make due with the Batman.
