Rita's ability is to create any object. However, she has to kill people to use it. The lethality corresponds to the number of people killed. A single person for a pencil. Each item has six uses (or six stabs in the pencil's case).

Michael has the ability to look like anyone. His eyes are the only thing that remains the same. In order to change form, he has to see the living person, no photographs. This means he can never change back into what he originally looked like.
