Kai Hakiaki Kelakei is a mutant from my story THOH. He's a strong conscious telepath whose body transforms into that energy thing wherever it's damaged severely.

This is basically a new design for Kai. Grayish blue hair instead of brownish red and red eyes instead of blue-green. And a better personality, but you didn't know that.

Kai doesn't speak or eat, since the energy can't do that. It replaces everything in the place of where it appears and it can imitate muscle movements and hardness of bones. It can also function as senses of sight, hearing and touch, but not smelling and tasting. The energy doesn't sense temperature or especially pain as well as skin though. Not eating will cause him trouble after a long time, but he survives until then due to the energy field generating stuff for him. (I've still got to figure how it does that...) It's kind of an force field, and the deeper you press, the more powerful is the repelling force. It's kind of like gravitation. Basically it's possible to press something all the way down through his body. It doesn't cause damage to him, though the pressure does feel unpleasant, both to him and the other object. Now, let's say, if a lift door was about to break his arm into two, the part that wouldn't be connected to to the body anymore deforms so that it gets sucked to the other side, and that is painful. I don't think he'd survive if that was done to his torso, but then again, his torso doesn't fully consist of the energy (yet). If the shutting door would be fast enough, a part of him might remain on the other side and wouldn't be able to connect to the rest of the body. In that case, the part left independent from the body would explode, and a new piece of energy would be formed where the previous one was. That hurts, but it's not dangerous, though if it happened often, he'd run out of energy, since he doesn't really get any energy from anywhere. Kai can control that energy field in a way that it works either as gravitational, electrical, electromagnetic or thermal energy. The base funtion is gravitation, as I explained (hopefully clearly enough). So, if he wants to for example give a person an electric shock, he can. The energy field often feels like body temperature. He can change the temperature inside with only a few degrees. Outside he can do a little higher or colder temperatures.
