Johnny Dee's powers have still not been confirmed as to whether they originate in his alien partner, or for that matter whether they are a mutation at all. When all other mutants had lost their abilities he retained his.
His power does not actually create "voodoo dolls." The term is used to denote the legends of the ability to kill or affect someone via a doll and using an unknown magic.
Johnny Dee needs to introduce a piece of DNA to his partner and then a construct (doll) is created that can be affected or even killed by damaging the doll construct. The mechanics of this power including its range, any limitations as to whom it can effect, or how long it lasts has not been determined.
Johnny Dee's whereabouts are currently unknown.
