After taking a significant risk and experimenting on himself with an insufficiently tested version of his Formula, doctor Bao-Wei Cong began to manifest a horrifying transformational ability that he has no power to stop. Like most other elemental mimicry powers, Bao-Wei's ability allows him to transform himself from a biological form into something wholly elemental in nature. However, unlike a proper evolved ability, Bao-Wei's power does not behave as he wills it to. His ice mimicry is a slow and gradual transformation instead of an immediate one, and a transition that he cannot stop and is wracked with excruciating pain from. Imagine if Abigail Beauchamp's ability caused her to slowly burn alive from the inside out, turning her form an ordinary woman through to a smoldering body and melting flesh and then out to living flame that she can never revert back from. This is what Bao-Wei Cong is experiencing, but far, far colder.
The ability begins as a dramatic drop in body temperature to a point of near hypothermia. Over the course of several days, Bao-Wei's skin coloration begins to change, taking on the pallor of a corpse with blue lips and pale flesh. Within a week's time frost has begun to accumulate on the outside of Bao-Wei's skin as ice crystals form inside of his muscles causing bouts of fitful agony. His breath at this point is exuded as a frozen vapor.
Over time, Bao-Wei's body begins to freeze. "Scales" of ice begin forming on top of and beneath his flesh, breaking through the skin after blackening the area nearby like severe frostbite. His core temperature continues to drop beyond levels that a human should not be able to survive, and Bao-Wei is constantly struck with a sensation of being cold, unable to warm up.
Eventually, his entire body is replaced by a "living ice" much in the way Allen Rickham becomes a man of living metal. Bao-Wei's ice form is not perfect or complete, portions of blackened and frost-bitten flesh are still visible, and his body is constantly freezing, sloughing off pieces and re-freezing new sections of himself. Bao-Wei's ice form is not particularly resistant to blows, but constantly regenerates by freezing moisture in the air to reconstitute itself, though it is a very gradual process unless in proximity to a body of sizable water. As such, damage dealt to Bao-Wei's icy form is largely ignored as he lacks pain sensory perceptions and internal organs to damage. He can reconstitute destroyed or lost limbs by appropriating the missing volume of his destroyed parts with water.
Additionally, Bao-Wei can control ice that is connected to his body by a factor of ten times his own mass. As such, were Bao-Wei to fall into a pond, he could emerge five times his normal size, encrusted in scales of ice. He could reach into a faucet and freeze five times his mass in water through the pipes, or touch a river and freeze a bridge across. Bao-Wei's external temperature on the surface of his body is -220 degrees Fahrenheit, comparable to that of liquid nitrogen and is capable of freezing most matter he comes into contact with. Dense materials freeze slowly (like concrete or iron) and less dense materials like a hollow tennis ball or human flesh freeze faster.
As such Bao-Wei structurally damages things that he is in prolonged contact with by the time he has reached the final stage of his transformation, including the ground under his feet. Air surrounding Bao-Wei is freezing cold and he exudes an area of chill that is -100 degrees Fahrenheit within five feet of himself, -50 degrees within ten feet and so on. Wind speed and direction can extend his chill away from his body. If he wills it, Bao-Wei is capable of creating the effect of diamond dust around himself in a windy environment.
Bao-Wei in this form is extremely vulnerable to melting and dissolution. As he can reconstitute parts of himself from moisture in the air it takes a dry prolonged heat to melt him. But effects such as a pyrokinetic's flame, molten steel (hi terminator 2, hi!) Abby's ability, a burning building and the like could kill him. If Bao-Wei is exposed to prolonged heat and flame to which he melts away entirely, he perishes. However, in his frozen form if a large enough portion of his body remains, he will be able to refreeze and reconstitute himself over time.
Bao-Wei has learned to control the temperature of his surface/skin. Previously, contact with his frozen form would cause flash-freezing and cell death; by condensing the coldest points of his frame inward, he is able to leave the outside shell layer at a survivable freeze. Maintaining center density takes considerable effort due to the encompassing, chaotic nature of his form, and so he can only keep a handle on it for so long, depending on the degree of pressure.
Secondarily, he has grown in his ability to influence the temperature and climate around him, causing a micro-climate in his vicinity; creation of ice comes more easily now, and he is able to construct more sizable, sturdy objects using his ability and a proper source of moisture.
