Paikuhan (also known as Pikkon in the English Dub) is one of the heroes who appeared in Dragonball Z and one of the many deceased heroes who now resides in Other World. He becomes one of Goku's rivals in the other World Tournament.
Paikuhan (Pikkon in the Funimation dub) appears in the other world tournament saga. He fights alongside many other warriors including Goku and Olibu, the winner recieving a lesson from Dai Kaio. Paikuhan made it to the final to face Goku, where they both tied because their feet touched the ceiling at the same time. (A form of ringout). Since then he's usually shown with those involved in the outer world, and makes in appearance in the twelveth DBZ movie Fusion Reborn, and is mentioned in DBZ movie Bio-Broly. He is shown to be at least as strong as a Super Saiyan, and when removing his weighted training clothing seen in picture he is even stronger.
Pikkon appears as a tall, humanoid, muscular, green warrior (roughly the same physical size as Goku). He dons white robes with a blue undershirt below them. He wears brown boots, a brown belt with a golden circle in the middle, and a type of tall turban-like hat that has a matching golden circle in the middle. He has flat ears similar to that of someone like Frieza, and no visible nose. When he removes his hat, black spots are seen on the top of his head.
Pikkon is a very wise fighter. He uses this to his advantage by planning out attacks. Pikkon even goes as far to correct Goku on his "sloppy" dodging and inability to concentrate, offering advice even in battle. When he first appears, he hardly speaks a word, but later opens up during his bout against Goku. Pikkon has heroic characteristics similar to Goku's, and fights for the good. Goku compares his personality to that of Piccolo, and even states that Pikkon and Piccolo would "get along great". In Fusion Reborn, he is seen becoming jealous when Goku gets to battle Janemba and he does not. He is also seen just as impatient when he asks Janemba where he came from, and he is shown to get quite angry when things do not go his way (an example being him yelling while trying to get the barrier encased around King Yemma's mansion to break).
