_{While in non-marvel settings ( spn / dc / whatever you wish / what i default to ) Ky uses vessels and is literarily black smoke when he’s not inside one, but he also has his true form that he can take on ( even while outside of a vessel  / body ).} 

_{However, in Marvel / 616 settings ( ironically his old main verse ) he does not use them. His body ( that you see him in ) is his own – so is his true form. He may change his appearance at times, but it’s still his own body. up to and including his true form / spiky mini-blackheart version of himself… otherwise known as his true form.}
