Skarlet

Skarlet is a very ferocious opponent in battle. She utilizes a slew of blades during combat, which she can use as both projectiles and melee weapons. Being composed solely of blood, Skarlet can utilize several blood-related techniques such as throwing orb-shaped projectiles composed of blood and can even morph herself into a red-liquid state which she can mold into structures.
