Eterna Rosenbloom

The Rosenbloom Family is more powerful than you could ever even begin to imagine.Eterna Rosenbloom is the current ruler of the Rosenbloom name. Her efforts and goals revolve entirely around her name, and as such invested her entire life to the family. She has many political alliances with many regions around the world.
Eterna always had an insatiable lust for perfection, dating back to when she was a child. Everything she does must be done without fail or error. 
Eterna’s childhood was very similar to Petals’, except she was raised along side on of the servant’s children, Lichi Lostlorn. They had become best friends, and to this day, they continue to stay together. Now Lichi acts as Eterna’s bodyguard, personal trainer, and advisor. 
She is incredibly skilled with the rapier, and despite her regality, she doesn't mind getting her hands dirty in order to achieve a goal. Incredibly fast on her feet, she tends to scratch at her opponent with her rapier with weaker strikes until they're incapable of fighting. Her rapier is specially crafted to have a hollow inside, which she injects poisons into from her hand. From there, the poison coats the blade from the tip with a flick of the switch.Why rely on others when you can do it yourself without the liability of error?If anybody manages to put up a fight with her, she has one more trick up her sleeve. She wears a necklace on her neck and a pair of bracelets on her hands, lined with tiny jewels of Awakening Emera that, when put in close proximity to one another, equates the strength of one Awakening Enema, allowing her to Mega Evolve. From her mega evolution, she is unrivaled in speed and toxicity, and her ability changes to Corrosion, being able to put down any opponent who dares to challenge her. However, due to the nature of her Emeras, they will slowly lose their power over time as the mega evolution persists, requiring her to stop fighting and recharge the Emeras in the same way as she does activate them, leaving her vulnerable.
You were a fool to believe you stood a chance against me. Wither away.
