Pikkon, known as Paikuhan (パイクーハン Paikūhan) in the original Japanese version, is a fighter of the Other World who first appears in the Other World Tournament. He does not appear in the original Dragon Ball manga. Acting as a substitute for Piccolo in terms of appearance, role, and personality, he is introduced in the filler episodes of Dragon Ball Z, and later appears in the movie Dragon Ball Z: Fusion Reborn.
Pikkon was once a fighter who lived in an unknown location in the West Quadrant of the universe. After dying a heroic unknown death, Pikkon was permitted to journey to the planet of West Kai, where he trained hard and became West Kai’s best student.
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 the Check-In Station to break).
Pikkon is the strongest warrior in the history of Universe 7’s West Galaxy. Even with his extremely heavy weighted clothing on, he showed no noticeable diminishing in his natural performance. His prowess was asked for personally by Grand Kai to take care of a villains’ rebellion in Hell. Without asking for any information on the foes. He calmly rushed to his assignment and swiftly defeats the strongest of enemies, knocking out Frieza and King Cold each with one hit, and similarly defeating Cell in two blows (albeit he caught Cell off-guard with his Burning Shoot).
During the Other World Tournament, Pikkon was able to easily advance to the finals, able to defeat Olibu, one of the North Galaxy’s strongest warriors, with only minor difficulty. In the finals against base Goku, Pikkon remained virtually unfazed by Goku’s initial assault. Once Goku fought seriously and his strength proved slightly ahead of Pikkon in his restrained state, he removed his weights, prompting Goku to use Super Saiyan. Despite Goku large power increase in power, the two warriors were basically on par with each other (although Pikkon’s profile in Dragon Ball: Raging Blast 2 stating that Pikkon had the upperhand). He is able to withstand Goku’s Super Kaio-ken. As noted by Goku, Pikkon is a very efficient warrior with virtually no blind-spots. This forced Goku to feign defeat long enough to catch Pikkon off-guard to finally eliminate the mighty warrior.
In Fusion Reborn, Pikkon is completely outclassed when faced against Janemba, being flicked away by Janemba in his first form and nearly killed with one blow by Super Janemba. By comparison, Super Saiyan 3 Goku beat Janemba’s first form with a few blows and put up a fight against Super Janemba.
