Danny Fenton

Danny Phantom (real name Daniel "Danny" Fenton) is the main protagonist of the original show and The Phantom Chronicles. He was a human boy who turned into a ghost/human hybrid upon stepping in through the Fenton Portal while in his parents' laboratory. His molecular structure is fused and rearranged with ectoplasm. As a result, he can transform from human to ghost at will, and he has several supernatural abilities. He works with his sister Jazz and best friends Sam Manson and Tucker Foley, in stopping villainous ghosts.
