Lilith

Once human, Lilith was turned into a siren, one of only six Sirens, a group of people with unbelievable powers, but no way to control them. She comes to Pandora in search of another Siren, in an effort to find out more about herself. Lilith is essentially the mage of the group, using her Siren powers to support the group and attack the enemy. Some of her powers include the ability to increase the group's rate of fire, as well as the power to create temporal bubbles, which she can manipulate to slow down enemies and hostile projectiles or speed up allies.
