One Piece's weakest Conqueror's Haki user is undoubtedly Eustass Kid. He's shown no signs of training or skill with the technique, as well as showing no signs of Advanced Conqueror's Haki. While it's likely he eventually becomes more skillful with it, Kid currently ranks as the weakest user of the form in the series.
