Powers
Sound Absorbtion: Can absorb sound to gain empowerments,  such as enhancements in speed, strength, durability, and stamina. And have you ever heard of sound having regenerative properties? Well to her they do. How strong she gets depends on how much she absorbs.  The downside is the sound she absorbs does drain after a while especially if she was to be put in a very quiet place. In fact she doesn’t like the silence for that reason. And as we’ve touched base of not enough sound, let’s touch base on too much sound. She does have a limit on how much she can absorb, and if she tried to absorb anything past her limit it would start to wear and tear her down having draw backs, with the similar feeling as if her brother was to hit her with one of his waves. She’d start to feel nauseous and dizzy, her ears would ring and she’d feel discombobulated and feverish.

Speed: You know the speed of sound? Yeah she cant go that fast...But! When she absorbs sound she gets a boost in speed and agility being able to move at a quarter of that, a nice 250 miles per hour max. To get to that speed, the frequency of the wave matters, as hertz (a wave passing passing a fixed point in a certain amount of seconds) tend to be slower the lower the frequency and faster the higher. This doesn’t mean low frequencies won’t give her a boost, it just means it wont be that great of a push. A sound as low as 50-60Hz will probably only up her speed up to 50 something mph, while a frequency of 2048hz (a high pitched scream) might up her speed to 150 mph, and something like a dog whistle, well that will easily set her to her max.  

Strength: Depending on how loud the sounds she absorbs are, she can reach a max strength to that of 5 tons of force, the momentum and  pressure force a turbine engine. So she’s pretty Stronk! it all depends on the sounds loudness, The higher the decibel, the stronger she gets. Some examples are if she were to absorb sound of around 60-80dB, a normal conversation, she’d only gain up to 500 lbs of strength, the sound of traffic might give her a boost to a good ton of force and if an ambulance or loud siren drove by, or if she were to go to a concert, well that might push her to her max.

Durability: Part of what makes her strong is the energy she gives off from the sound she takes in, it coats her in a field that makes her form pretty durable, wether its the vibrating of her molecules or if its her giving off some of those waves she’s absorbing, it gives her the advantage of being a bit tougher to beat down. She gains Peak Human Durability, so she’s able to take some hard punches, some swings from a bat or other hard objects, and falls from certain heights, being able to withstand an average 2 tons of impact force.

Sonokinetic Regeneration: Absorbs sound to heal and regenerate. The speed and amount she can heal is affected by how much sound she absorbs and at what loudness. The louder the sound=the faster she heals, the more sound=the more she can heal. Although she can heal pretty catastrophic wounds, she is unable to regenerate any removed or severed limbs, and she can’t come back from the dead. If the injury is fatal or damaged beyond repair well...


Skills
Has quite a talent when it comes to singing, some would even say it puts them in a trance...it doesn’t, she doesn’t have that power, some just say....she’s pretty good.
Don’t really know if this is a skill, but she counts it as one, she’s pretty good at reading people, their actions, what they’re thinking.

Abilities
Acrobatic and nimble, she tends to love being active. She also takes kickboxing and fighting a lot more seriously than her brother.
TwinkleToes- She’s light on her feet and most of the time super silent, having to pay close attention to hear her coming. She’s also quite the dancer, loving to lose herself in any rhythm.

Physical Weaknesses
Without sound she’s just your average human. Put her in a sound nullifying area and she’s S.O.L.
Trying to absorb more sound past her limit make her sicky sick.

Mental Weaknesses
She hates the silence, complete silence makes her feel uneasy, and anxious, almost to the point of panic.

Equipment
Nothing but the clothes on her back.



Personality
She’s charismatic and as her brother puts it, loud and rambunctious. She’s also spunky, as she has an attitude that won’t hesitate to bite. She’s a girl who knows what she wants and what she likes, and if she doesn’t like you she’ll let you know as she has no filter when it comes to speaking her mind.
She also loves a challenge, fighting, and pushing herself, if it was sound, some would even say fire fueled her.

History

Her twin brother and her were experimented on by their father at a very young age, which of course granted them their abilities. On the night their mother discovered what their father was doing in the shadows, she confronted him and in fear of being exposed, their father killed their mother. Her brother’s powers activated first and although the tried fighting back, he wasn’t strong enough yet, and didn’t full have control of his powers. In fear of also losing her brother, Eunji attacked their father and in that instant her powers were activated, giving her the strength to silence him once and for all.
