Pakku or Fakku was a senile old wet stuff bender from the North Pole. He is an instructor and master in the acient arts of peebending. He has great skills, but he was also anti-femminist as he refused to train Katara the arts of peebending, because of the fact that she was a girl. Pakku is very serious about his arts. he was so serious that arcording to the rumors of his fellow masters, Pakku once peed from the top of the highest building of the North pole just to prove a point that he was the best waterbender in the arts of peebending in the entire North Pole.
He eventually made an exeption for Katara, only because she had a full bladder during that time and he saw potential in her. Pakku was also a member of the Order Of the Pimp masters and helped his fellow pimps with the liberation of Ba Sing Se.
