At one point during his time in TNA, Hardy was also able to embrace a different persona with Willow. It was a much darker and hidden element of himself. He did this with the aid of a mask and makeup. Hardy's creativity has never come into question, and therefore, it is impossible to separate both the man and the persona.
Jeff Hardy rose to prominence in the WWE and it is his name that is as much a part of his success as it is what he has done in the ring. He is among the present WWE stars that is long tied to his name.
