Powers

1.Supernatural Strength-One of the two powers Esdeath gained from drinking the demon blood was a physical enhancer, which has allowed her to perform strength feats normal humans can't do.Currently her max strength is 10,000 tons. 
2.Supernatural Speed-Esdeath is incredibly fast, her reflexes exceed speeds beyond bullets, explosions and even lightning which can move at 270,000 mph.(Yes I looked this up and it's true)
3.Supernatural Durability-Esdeath's skin, bones and muscles have become dense enough to not be fazed or damaged by bullets, explosions equal to kilotons worth of TNT or even most of Winter's attacks.
4.Supernatural Regeneration-Esdeath's healing is much higher than what normal Auras tend to be able to heal.Esdeath is able to heal from mild wounds like broken bones to severe wounds like torn of limbs and impalement through the stomach to even fatal wounds like her neck being snapped, her organs being damaged, and shattered bones in mere seconds.Her healing also grants her immunity to drugs and poisons.
5.Supernatural Stamina-Esdeath is able to fight for a max of 5 days without rest.
6.Cryokinesis-Her semblance allows Esdeath to create powerful ice from nothing while also manipulating it to either create weapons,a whole army or to freeze whole cities on her own without her really having to suffer any drawbacks.
7.Very limited Chronokinesis-Esdeath's Ice is so strong and cold that she is capable of freezing space and time though only for a short time and this ability can only be used once a day.
8.Psionics-Esdeath's second power from the demon blood is a plethora of psychic powers that only grew stronger from her training.
9.Mind Reading-Self-explanatory.
10.Telekinesis-Can move objects with her mind.
11.Telepathy-She can perceive and interact with a person's mind, consciousness and thoughts by simply using he mind.
12.Telekinetic Healing-Esdeath can use her psychic energy to heal others even from fatal injuries.

15.Flight-Self-explanatory.
