I'll be honest, it would be very funny if there was a chara on earth that could follow the movement speed of the body of a user in the One Piece world and even the speed in the Bleach world is called shunpo which exceeds the speed of sound except for mutants with speed abilities, if I'm not mistaken Yoruichi's shunpo speed even reaches exceeds Mach level several times right?
