Her name is Ludmilia Serenity. Inteligent, quiet and serene among all problems. She lives in a poor and dangerous neighborhood in a poor family. Her two brothers are thiefs and into really bad bussiness. Her Cutie Mark is a Beaker with a green substance. Her love for chemistry came from his high school teacher whom with great charisma cautivated Ludmila's mind.

Ludmila's dark side comes from the hatred the crime organization commit uppon the lives of thousands and she does not chase after the autorities but acts on his own secretly synthetising her own venoms to kill in one shot bad ponies or to make the death longer and painfull for her victims.
