## Biography

### Birth of the Joker

Reliable accounts of the Joker's varied and altered past are slim. He has told by his own admission that he remembers his past differently, recalling it to sometimes be one way or the other. Numerous patient interviews and attempts to gain an understanding of the Joker have failed to produce an accurate depiction of his past and the events that gave shape to him save for one consistent undertaking in his story: his encounter with the Batman.

While acting in the identity of the Red Hood, he allegedly either tripped or was pushed into the vat of chemicals by Batman while the latter was lending pursuit at the Ace Chemicals building. The resulting chemical reaction made the Joker's skin a pale white and his hair a jade green. It also gave him his trademark crazy smile.

## Powers and Abilities

### Powers

* **Unique Physiology:** Upon submergence in the vat of chemicals he fell into, it is speculated the chemicals altered his physiology, granting him distinctions otherwise absent in normal humans.
	+ **Pain Resistance:** The Joker is extremely resistant to pain and most forms of physical suffering that would otherwise impede/impair humans for long periods of time. While not incapable of feeling discomfort, his pain resistance makes the pain he experiences in his pain receptors mild.
	+ **Toxic Immunity:** The Joker is immune to certain toxins and poisonous substances which would otherwise impair or kill a human if consumed or inhaled.
	+ **Tainted Blood:** It is heavily implied the incident which gave the Joker his trademark bleached skin, jade green hair, and his crooked maniacal smile has also tainted his blood. Blood transfusions between the Joker and lesser fortunate parties usually end in the deaths of the recipients. His blood is considered incompatible with other forms of life, and even mosquitoes languish when they suck his blood.

### Abilities

* **Escapology:** The Joker typically escapes confined areas designed to contain him and often finds his way loose of restraints.
* **Chemical Engineering:** The Joker is well-versed in chemical engineering, employing the use of chemicals (that are often dangerous and extremely volatile) to aid him in his exploits. He is the inventor of Joker Venom ― a chemical that, when inhaled or forced into contact with a victim, causes a person's face to assume the fixed expression of a rictus grin and, in other cases, assume features resembling the Joker himself such as his bleached skin.
