Alecto

Designed to be the ultimate killer and assassin, Alecto takes sadistic glee in ending the lives of anyone who gets in her way, and even those who were just minding their own business. She is able to generate blades of pure psionic energy from her hands that are capable of slicing through virtually any substance like butter. The energy penetrates down to the molecular level and forces the bonds apart, even in something as dense as diamond. The effect this has on living organisms is excruciating beyond words, and Alecto likes to let her blades linger in victims to see how loud they will scream.

Alecto doesn't care about taking over the world or taking revenge on humanity. So long as Typhon lets her kill people, she's happy. She actually doesn't want to wipe out humanity completely, since then she'd have no one to play with.
