<P> Toriyama originally created Krillin along with the Tenka'ichi Budōkai as a method to help add depth to the story, as his editor Kazuhiko Torishima had stated that the series' protagonist, Goku, was too plain . Torishima explained that in order to develop Goku's characterization, they needed someone petty and mischievous to provide contrast . Leading to the introduction of Krillin . Yūsuke Watanabe, who wrote the screenplay for the film Dragon Ball Z: Battle of Gods, had originally written the film to take place at Krillin and Android #18's wedding, but Toriyama wrote it to take place at Bulma's birthday party . Watanabe thought Toriyama made the change because he wanted fans to imagine the wedding for themselves . Toriyama cited Krillin and Bulma's older ages at the end of the manga as a reason he chose for Battle of Gods to take place after the Boo arc since they were in their "strongest condition at that time ." </P> <P> Krillin's appearance stays relatively the same for the majority of the series . He is first introduced at age 13, with a shaved head and still dressed in the yellow - and - orange clothing worn at the monastery at which he had been training . He does not possess a visible nose, and has six spots of moxibustion burns on his forehead, a reference to the practice of Shaolin monks . Toriyama once stated, seemingly humorously, that Krillin's lack of a nose is because he has a "physical idiosyncrasy" that allows him to breathe through the pores of his skin . Later, he wears the orange gi uniform that is presented to both himself and Goku by Kame - Sen'nin in honor of their first martial arts competition . Occasionally he is seen in casual clothes, but for the most part continues to dress for training or fighting at all times . During the Freeza arc, he wears Saiyan armor provided by Vegeta, but during the Cell arc he returns to wearing the orange gi, accompanied by a blue short - sleeved undershirt and boots . After the defeat of Cell, Krillin stops shaving his head, and grows his black hair out, before later shaving it again during Frieza's resurrection . When he settles down with his family, Krillin is shown wearing a workout outfit consisting of a red T - shirt and brown drawstring pants . </P> <P> Krillin first appears arriving at Kame - Sen'nin's island to become his apprentice, meeting Son Goku, and the two become rivals . However, after doing the hardships that Kame - Sen'nin assigns, the two become friends . After finishing their training, Kame - Sen'nin has Krillin and Goku compete in the 21st Tenka'ichi Budōkai . Krillin beats the odored fighter Bacterian, who uses his stench as a weapon, and makes it to the semi-finals . However, he is defeated by Jackie Chun, who is really Kame - Sen'nin in disguise preventing his students from becoming arrogant with too many victories . Krillin continues to train with Kame - Sen'nin and helps Goku to collect the Dragon Balls by fighting against General Blue and participating in Baba Uranai's tournament . However, he is quickly defeated by Dracula Man, who bites down on his head, causing blood to pour out . Three years later, Krillin enters the 22nd Tenka'ichi Budōkai . Again, he makes it to the semi-finals by defeating Chaozu, but loses to Goku . Soon after, Krillin is killed by a henchman of Piccolo Daimao, who wanted to steal Goku's Dragon Ball . After Goku defeats Piccolo, Krillin is revived by the Dragon Balls . Another 3 years later, Krillin enters the 23rd Tenka'ichi Budōkai . This time however, he only makes it to the quarter - finals, losing to Piccolo Junior . Krillin then tries to intervene in the fight between Piccolo and Goku when Piccolo gains the upper hand, until realizing he is outclassed . </P> <P> Several years later, in the span of a day, Krillin is attacked by Raditz while attending a reunion, and is unable to save Gohan from Piccolo, who takes him for training . A year afterward, Krillin confronts the Saiyan invaders Vegeta and Nappa along with his friends, following months of training in preparation for their arrival . After Yamcha's death, he avenges his friend by killing most of the Saibermen . In the battle against Nappa, Krillin tries to get involved in his fight with Tenshinhan after Nappa severs the latter's arm, though is stopped by Nappa . Krillin double teams Nappa with Piccolo, creating multiple copies of themselves with the Tri-Form and failing thanks to the clones cutting their power . Krillin later goes toe - to - toe with Nappa alone, launching a Kienzan at him that Nappa almost catches before Vegeta warns him, and is saved from an attack from Nappa by Piccolo . After Nappa is defeated, and Goku arrives, Krillin requests that he fight Vegeta elsewhere to prevent their friends' corpses from being destroyed . He and Gohan leave the battlefield but return after Gohan worries for Goku, who is being crushed by Vegeta in his Oozaru form . Krillin unsuccessfully attempts cutting Vegeta's tail in a sneak attack, and later is given the Genki Dama to launch at Vegeta by Goku, which misses initially but is bounded back by Gohan . After Vegeta yields from further conflict given his extensive injuries, Krillin takes Yajirobe's sword and moves in to kill him, but agrees to spare his life per Goku's request . He then travels with Gohan and Bulma to planet Namek to use the Namekian Dragon Balls to revive their dead friends, since the Earth's Dragon Balls vanished due to Piccolo's death . Once there, they save a young Namekian called Dende from death at the hands of Freeza's henchmen . Krillin receives an increase in power from Guru, the grand elder of the Namekians, when he unlocks his hidden potential . After a few close encounters with Vegeta, Krillin and Gohan are forced to team up with him in order to fight Freeza's strongest warriors, the Ginyu Force . They are overpowered by them until Goku arrives and defeats the Force . After Krillin and Gohan collect the seven Dragon Balls and wish back Piccolo, they begin a battle against Freeza, during which Krillin is stabbed in the chest, removes Freeza's tail following being healed by Dende, thereby distracting Freeza from continuing to crush Gohan to death, and injures Vegeta in an attempt to capitalize on his Saiyan ability to grow stronger when in a near - death state at Vegeta's request . After a long fight between Goku and Freeza, Goku decides to use the Genki - dama, Krillin giving his energy to Piccolo so he can stall Freeza and attacking Freeza himself with his last bit of strength . When the group recovers from the Genki - dama, and Freeza emerges unscathed, the latter detonates Krillin from the inside, killing him instantly, which triggers Goku's first ever transformation into a Super Saiyan . After Freeza's defeat, Krillin is revived by the Namekian Dragon Balls . </P>
