For me it would have to be G-Dragon. I always found him to be one of the more unique idols for his charisma, his stage presence and his style. You know who he is and I really don't think you could ever forget who he is. G-Dragon has quite the status but he has always remained humble and grateful and even has gone out of his way to support and mentor younger idols. He puts his heart and soul into his work and that becomes apparent when one looks into his music and performances whether solo or with BigBang. I feel that he is one of those people who only come once in a lifetime and cannot be repeated or replicated. Even if one did try to repeat what GD has accomplished, I think it would be very difficult. There's only one G-Dragon after all.
