My dark side (1/2)

Based on Resident Evil, I created a version of mine with a mtation.

Bio:
Name: Michael
Age: 17
Powers: can change its structure, making it stronger, pulling bone spurs, and change its shape.
History: It was the test subject for a vaccine that would try to make people immune to other viruses and maintain stable health. They injected it, and not seeing any side effects left him. But at night, had a nightmare and stress I caused a mutation. Went to scientists who created the vaccine, and they will investigate the reason. Thanks to the discoveries of its cells, were able to avoid these effects. The reason was that the antibody had mutated because they were unstable and the active stress defense mechanism in the body. Was in observation, and disappeared after his mutation, and to be sure, they checked his blood. There was nothing unusual, everything had returned to normal, with exception of a few black spots on their cells, was not given importance. And I returned to normal life, but then discovered that in some situations that eluded him his mutation and other could control it.
