Lady Justice

Lady Justice is always out to seek freedom and peace in Equestria. She is known as Manehattan's protector, but she is always there to lend a hoof to others in need of help.

Origin
Sierra is unicorn mare from Manehattan. A few years ago, She worked in a science lab along with many other ponies, helping create inventions for many different cases. One day She came across a super serum that was put away in deep storage. It was once tested on an pegasus, but caused the pony to transform into a monster, bringing harm to the citizens, which gave the princesses no choice but to have him banished to a far away land. Because of her curiosity, She tested it, almost killing herself. But before major side effects had accrued, she managed to cast a resistance spell on her body. After the serum finished, it gave her super strength, and she even gained a magic boost, giving her more possibilities to spells that no normal unicorn could achieve. A few days after she gained these powers, she tested a new spell on a Shield she made, it became nearly impossible to destroy, And with that, she used it as her weapon in action. after she trained up her powers for a few months, she committed herself to keeping the city safe from outsider's harm.
