As Danny Phantom, he freely uses a variety of supernatural powers. In either form, Danny (as well as all other humans) can see, hear, and speak to other paranormal beings, as well as battle them. Danny possess most of his supernatural powers in both his dual forms--although he only uses them most freely in his ghost form. The only exception is that so far Danny cannot utilize his supernatural strength in his human form. Also other ghosts can sometimes overpower him and impose invisibility and intangibility (or lack-there-of) until Danny can regain energy and fight back. To save his friends and family, Danny frequently battles with various ghosts, sometimes from thwarting plans of world domination or confronting them in situations of public disturbances.
