He would be able to transform into his 2d shadow form is a pitch black hole would appear below him and sink him inside and then he would come out as his 2d shadow, his whole body is just a wireframe line that makes his whole body, and white empty circles for eyes, and he cannot get hurt or die when in his shadow form. How he got his name is from his childhood best friend, Jay, when they first met when Jay was only a kid and when Dem was just a small shadow. Dem actually doesn't know his own age.
