Krillin

, known as Kuririn in Funimation's English subtitles and Viz Media's release of the manga, and Klilyn in Japanese merchandise English translations, is a fictional character in the Dragon Ball manga series created by Akira Toriyama. He is introduced in chapter #25 "A Rival? Arrival!!", first published in Weekly Shōnen Jump magazine on May 21, 1985, as Goku's fellow martial arts student under Master Roshi. As the series progresses, Krillin becomes Goku's closest ally and best friend as he fights every villain along with Goku or before him and is often depicted as the comic relief.

== Design and appearance == Toriyama originally created Krillin along with the Tenkaichi 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 to develop Goku's characterization, they needed someone petty and mischievous to provide contrast, thus 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 Buu arc since they were in their "strongest condition at that time."
