Blister is often regarded as one of the most dangerous dragons in Pyrrhia. She is fiercely intelligent and cunning, cold, manipulative, critical, and is known to have horrifyingly effective torture methods. Blister always gets what she wants eventually, either by playing the long game or by using flattery or threats on important targets. Even when standing beside her larger, battle-scarred sister, Blister is the most terrifying. She is eerily still with a menacing aura and dangerous look in her eyes, and her face, though not always her voice, conceals all emotion. Blister's voice is described as "cold, hard, purring, icy, and slithering with a strange hiss to it."

TLDR: Dangerously smart and ruthless
