Character from League of Legends.

Limitless because of the possible depictions of violence and blood.

A failed experiment by the Black Rose, Briar's uncontrollable bloodlust required a special pillory to focus her frenzied mind. After years of confinement, this living weapon broke free from her restraints ( yet to break free in this scenario) and unleashed herself into the world. Now she's controlled by no one—following only her hunger for knowledge and blood—and relishes the opportunities to let loose, even if reining back the frenzy isn't easy
