Mimic

undefined:

A system member who can only appear as other members of either their system or another system. They are not a midtroject because they only appear as the person due to not having a visual or physical form of their own, or due to a similar effect as singletsona. They are not the person they are appearing as and are aware of themselves not being that person. They can look like anyone apart of their own or another system. Similar to a shapeshifter and interra.
