Giran is a Giras that entered the World Martial Arts Tournament. Although he is initially hostile against Goku and his companians, he later comes to respect Goku and even cooperates with him on more than one occasion.
Ruthless and hard-of-heart, Giran is always eager to fight, and enjoys pounding anyone foolish enough to challenge him. This enormous dinosaur-like creature is able to fly using his powerful wings. He also spits out a strange gooey substance he calls his "Merry-Go-Round Gum," which he uses to trap his opponents. Giran is something of a bully and in one episode he was shown stealing a fish from a few bears. He seems to be very self conceited and selfish. However, he is not without kindness. Though he often seems cruel, brief glimpses of the good part of him are seen. When he is not fighting, Giran has a voracious appetite, and enjoys washing down his considerable meals with a few cold glasses of milk. However, he is wasteful and throws a half-eaten chicken drum across Competition Hall when eating with Goku at the World Tournament, which disgusts another contestant, Nam. When he meets Goku right after the tournament, he is respectful to him, because of their fight. Still, Giran seems to love tormenting people and threatening to kill them. However, the fact that he was twice revived by the Dragon Balls proves that he is not truly evil.
He competes as one of the eight finalists in the 21st World Martial Arts Tournament and fights Goku in the Quarter Finals. Early on before their match he also gets close to a bar fight after a hungry Goku steals a large amount of his fried chicken he was eating and knocked over his milk bottles. Giran later got into another after his match with Goku is interupted by the rain and they stay at a bar for the night so they can finish their match tomorow, when some intoxicated Orin Temple students including the Bullies of the Orin Temple started teasing him for ordering milk at the bar (Giran threatened to kill them and beat them all in an outnumbered fight before ordering another bottle than getting into a fight with Yamcha until Master Roshi calmed him down), it should be noted however that the entire bar scene is a filler of the anime.
In his fight against Goku, despite using a number of underhanded tricks as well as his powers of flight and his Merry go round gum, he forfeits after Goku breaks out of his gum and shatters a wall with a kick.
Red Ribbon Army Saga
In a filler episode that happened shortly after the end of the 21st World Martial Arts Tournament, it was shown that Giran's race, the Giras, was responsible for the drought that plagued Nam's village. They had used their gum to block a waterfall of the roaming lake (a never ending stream of water that passed through Nam's village every generation or so and with it sealed up they messed the water this generation and they have been trying to sell carrots to make money to buy water) so they could use the water for their own selfish needs. Giran and his race have been using it for themselves ever since they innherited it and at one point one of Giran's Men tries to make Nam pay to let the dam be broken when in fact they could not break it themselves even if they tried. Goku defeated the monster beasts and Giran arrived following their defeat. Giran agreed to release the dome made of merry go round gum that was blocking the water channel if Goku could break it down, which he does with his Kamehameha wave.
King Piccolo Saga
Three years later, Giran is shown to be passing his time tormenting a storybook-esque village's inhabitants and stealing their food. Giran was about to beat up two bears after stealing their fish, when he was attacked by Tambourine, due to his name being on the martial arts tournament registry from when he participated in the 21st tournament.
Of all the martial artists who Tambourine killed, he lasted the longest against the evil Namekian. Giran put up a better fight against him than Goku, because Goku had been weak from his fight with Tien Shinhan, and even managed to strike Tambourine in the face with his large powerful tail, although it caused little to no damage. Tambourine retaliated by ramming his hand clear through Giran's body. After killing Giran, Tambourine killed one of the bears who thanked him before coldly telling the son that he killed the papa bear for fun. He is later brought back by the Dragon Balls.
Dragon Ball Z
Kid Buu Saga
Years later, Giran dies from either Super Buu's Genocide Blast or Kid Buu's Planet Burst. He was revived by Porunga and contributed to Goku's Super Spirit Bomb to defeat Buu.
Flight – Giran and his race can fly using their wings.
Superhuman Strength – Giran has superhuman strength that exceeds that of the average creature on Earth.
Tail Attack – Giran can attack his apponent with his large and powerful tail.
Merry-Go-Round Gum – Giran and his species can shoot a strange elastic rubbery gum like substance out of their mouths called "Merry-Go-Round Gum". The gum encases the opponent and wraps around their body tightly. According to Giran, the more the victim struggles, the tighter it becomes. However, if a victim is strong enough, they can possibly break out of it. Giran uses this move twice, first on Goku and again on Tambourine, who both easily broke free. Much later in the Dragon Ball series, Majin Buu uses a similar attack on Majin Vegeta.
Video game appearances
Giran is a boss in Dragon Ball 3: Gokuden and Dragon Ball Z: Super Gokuden: Totsugeki-Hen. He appears as a boss and playable character in Dragon Ball: Advanced Adventure. In Dragon Ball: Origins he is a boss in the 21st World Martial Arts Tournament, as well as in two bonus chapters: in an exhibition match after the final of the tournament and on Mount Paozu. On Mount Paozu, Goku thought Giran blocked the river because Giran planned to invite his friends there; in fact it was Goku who blocked the river early in the game to gain access to a secret cave with Bulma, but Goku only remembered this after Giran's defeat.
