Tiamat

Tiamat was a unique Lawful Evil chromatic dragon, who had one head for each primary color of the most common species of chromatics (black, blue, green, red, white). Each head was able to operate entirely independently of each other and had the powers of a member of the respective race​ of dragonkind. Her body also had traits in common with a wyvern, including a long tail tipped with a venomous stinger

​

Tiamat was also the eternal rival of her brother Bahamut, ruler of the good metallic dragons.

Mental characteristics

Intellectual Characteristics

Tiamat was arrogant, greedy, hateful, spiteful and vain. She never forgave any kind of slight[30] and was focused on obtaining more power and wealth. She disdained mortals, regarding them as mere disposable tools in her schemes. When needed, she was charming and fey, but her self-serving and reptilian personality betrayed her sooner or later.
After having experienced relative mortality as an archfiend, she became less reckless but also paranoid.
Tiamat enjoyed the company of dragons, and had many great wyrm consorts of the chromatic varieties.
She had an insatiable greed for treasures, but preferred that her followers brought it to her in the form of gifts instead of searching for riches on her own
