Emma the Rabbit (Crossverse)

History
Emma was born with the special metahuman gift of super-eyes and a super-brain, at the cost of that same DNA being the reason why she has aphonia, making her mute.

She was part of a hidden ninja clan which focused on the power of chi, but due to her abilities, she quickly mastered all forms of combat training they could have given her, making her one of the top elite forces by the age of nine, though as the years went by and she reached puberty she eventually lost that position due to her nymphomaniac personality.

As time went on, the ninja clan began to falter due to treachery from one of the elite members, and eventually, Emma had to actually resort to living in urban areas to make money via thievery and the occasionally killer contracts.

Because of her abilities, as time went on, Emma became extremely versatile in a variety of different subjects in like to get by on her own.

Space Blade
A handle that when activated, bends space into a certain shape. When Emma charges chi in her hands holding the blade, it shoots out into this folded space and takes the full shape of an chi blade. Because space is folded in, Emma can channel a large portion of her chi energy into this point to increase the penetration power of the sword against comparable chi opponents.

Sniper Rifle
On its own, it's a normal rifle, but with Emma charging chi into the ammunition rounds, the rifle becomes capable of firing light-speed blasts of chi, far faster than what she's capable of throwing.

The grip's grooves were seemingly made just for her to fit perfectly. In fact, this was intentional. The rifle fails to fire if someone else is holding it, which is noticed via fingerprints. If charged with chi despite not being the right fingerprints, the rifle self-destructs with the contained chi, damaging the user.

Gauntlet
The gauntlets that Emma wears have hidden blades that have a direct connection to Emma's chi, allowing her to have hidden chi-blades at will.

Enhanced Reaction and Processing Speed
Emma's eyes perceive things down to nanoseconds, and her mind is fast enough to process and react to this. With a mind as fast as this, Emma has the capability of perceiving a decade within 0.072576 seconds. In comparison, peak human (quite possibly superhuman) reaction speeds would allow one to react in 0.08 seconds. This speed allows her to study an environment long enough to: In order for her body to keep up with her eyesight, her synapses transfer information at the speed of thought, essentially making her body move as fast as she thinks of what she wants to do.
 * figure out how traps work and escape seemingly impossible-to-escape traps
 * decipher illusions
 * calculate probabilities and solve situations at a rapid pace
 * learn things literally hundreds of times faster than the average person
 * seems to never miss as she always has all the time in the world to make the perfect shot
 * fluently move through an environment
 * concentrate on multiple things at once
 * quickly read and memorize things upon looking at them seemingly instantly
 * Can quickfire with extreme accuracy, practically never missing her first shot against opponents of comparable speeds
 * overload and potentially incapacitate mind-readers with over 130 years of information every second

Enhanced Eyesight
Emma can locate individuals from up to three miles away with her eyesight alone. This intense sight also allows her to take in more light, giving her a limited version of night vision.

Life Force Control
By learning to control her Chi, Emma can create a thin invisible aura around herself, allowing her to:
 * enhance her physical might to the extreme, allowing her to compete with other metas and very casually dispose of non-powered individuals.
 * increase her longevity to stay young for decades longer than other individuals in the same species
 * grant her immunity to most external forms of poison and disease, and increases her ohms.
 * sense the chi of others to tell where they are, even if invisible, and how strong they are
 * sense and read supernatural abilities and weaknesses of others
 * mask her own life energy
 * heal herself and others on both a physical and spiritual level
 * allows her to traverse her environment without interacting with the air around her, making her silent for anything in the air
 * draw energy from others with melee attacks, weakening them to level the playing field and possibly even turn the odds in her favor. She can even disrupt the flow of chi in the body, such as reversing it to sharply lower their durability, and outright stopping the flow to temporarily paralyze them or negate certain chi-related abilities for a short period of time.

Combat Master
Emma is a master of multiple martial arts: karate, boxing, taekwondo, judo, muay thai, jujutsu, jeet kune do, aikido, krav maga, tai chi, hapkido, kendo, kenjutsu, and naginata.

Hyper Intelligence
While not the scientist type, Emma's high perception and processing rate allows her to learn things extremely quickly. She is an expert thief, engineer, tech specialist, combatant, gunner, etc, and began to use her skills in a large variety of ways to manage to live on her own.

Flaws
Should there be a condition where she needs to speak..... well she can't.

Emma can tend to not be fearful of situations when it's probably better to, as that could lead to a bad case of overconfidence.

Her nymphomaniac nature could leave her vulnerable to attack.

Emma can tangle with tougher foes due to her reaction speeds and equipment usually bypassing conventional durability. She is actually at a physical disadvantage against most of her foes.

Trivia
With her eyes working on overdrive to understand her environment, it will be moving at relativistic speeds, which is far too fast for the normal eye to see. As a result, some people claim that Emma's pupils and iris disappears, and they mistake it for Emma fighting serious.

Emma is infertile.
