Lin Fei awakened as Krillin with Saitama’s strength and began adapting through intense training, while his growing closeness with Bulma and rivalry with Yamcha shaped his return to the World Martial Arts Tournament. Krillin advanced to the quarterfinals, while Goku won his match against Chi-Chi after recalling their childhood promise to marry.
Krillin defeated Piccolo, Mr. Shen, and Goku to win the tournament, then married Bulma and used Shenron to help everyone survive in space. As Krillin prepared for the Saiyan threat, Golden Haired Lanchi entered his life and the System assigned him a new mission.
Krillin strengthened his family and allies while preparing for the Saiyans, guiding Goku to King Kai and developing powerful new techniques. The arc ends as Krillin brings Goku back to Earth and Vegeta and Nappa descend toward the assembled fighters.
Krillin defeats the Saiyan invasion, then travels with the others to Namek to oppose Frieza’s forces and gather the Dragon Balls. After gaining new power through the Sacred Baptism, he leaves Vegeta to settle his grudge with Sabo and destroys Zarbon, completing the Namek mission.
Krillin and the others fought Frieza on Namek while restoring the Namekians and helping Goku face Frieza’s transformations. After Frieza killed Krillin, Goku became a Super Saiyan and confronted him with overwhelming power.
After defeating Frieza, Krillin led Earth’s fighters through new training and personal changes before traveling with Trunks to a future ravaged by the Androids. The group confronted Android 17 and Android 18, and Goku, Vegeta, and Piccolo prepared a combined attack on 17.
Krillin helped Trunks restore Earth and revive its dead, then transformed Future Android 18 into a human and brought her into his family. As Bulma began creating an embryo with immense potential and the fighters trained, Yamcha confronted Android 20 and was badly outmatched.
Krillin guided the heroes through the battles with Dr. Gero’s Androids and Cell, while Goku and Trunks defeated their enemies. Afterward, Krillin turned Androids 16, 17, and 18 into humans and brought the androids into his life, leaving him and Lazuli to face a confrontation with thugs.
Krillin transformed Tien Shinhan, Yamcha, and Chiaotzu with Eternal Energy Reactors, then took his allies through time to learn from Master Mutaito. Master Mutaito awakened a Martial Dao God Core while Zamasu empowered Cell in the future and helped him reach toward his Perfect Form.
Krillin completed his transformation and returned to face Zamasu and Purple Cell, sealing Zamasu and empowering himself. As Golden Cell overwhelmed the fighters, Krillin inspired Gohan to unleash his hidden power, and Gohan defeated Cell.
After defeating Cell, Krillin restores Trunks’s future and helps unlock new powers in the children and those around him. The family grows, Frieza vows revenge, and Trunks and Gohan begin their superhero work as Lansa returns from school.
Krillin confronted Babidi and Majin Buu while the Z Fighters prepared for Buu’s threat. The Saiyans regained their tails and awakened new power, while the Old King of Gods began drawing out the group’s potential.
Krillin and the Saiyans defeated Buuhan, then faced Kid Buu as Goku, Gohan, and Vegeta awakened new forms with Bulma’s Bruits Wave device. Krillin’s guidance earned him a major breakthrough, while Satan and Ailins approached the battlefield amid the scattered fragments of Kid Buu.
Krillin assembled a team to explore the Demon Realm, where they met Paji, collected the Third Eyes of the Demon, and defeated Sphere God No. 3. The group prepared to cross into the Second Demon Realm after Krillin began tearing open the spatial barrier.
Krillin’s group explored the Demon Realms, recovered Piccolo’s Dragon Clan origins, and helped Aki restore his soul. After reaching the First Demon Realm to claim its Dragon Ball and Buu fragments, Fat Buu absorbed the Majins and transformed into Ultimate Buu, who overwhelmed Goku.
Krillin and the others defeated Goma’s rebellion and gathered the final Demon Realm Dragon Ball. At the Lookout, Piccolo underwent a series of transformations and emerged as Orange Piccolo, a new ally whose power matched Beerus’s level.
Krillin returned from the Demon Realm with immense power and worked with Piccolo to purge the Dragon Balls’ negative energy, releasing the Evil Dragons. Earth's fighters split up to face them, while Yamcha saved Fei'er and Tien and Fat Buu defeated their foes.
Vegeta, Goku, and Gohan fought the Shadow Dragons as Syn Shenron seized Dragon Balls and grew stronger, overwhelming their allies. Goku absorbed the Four-Star Dragon Ball’s power and knowledge, then struck Syn Shenron with a new golden-red energy as the battle continued.
Goku defeated Syn Shenron after awakening Super Saiyan 5, and Piccolo upgraded Earth’s Dragon Balls while Krillin completed his fusion. After returning to Capsule Corporation, Krillin rescued Vomi from Dr. Gero’s laboratory and reunited her with Gevo, then recruited her to his research team.
Krillin helped Vomi and Ailins transform, uncovered Mr. Popo’s ancient role in guarding the Ancient Demon King, and led the creation of new divine cores for Tien Shinhan, Chiaotzu, and Yamcha. After Beerus and Whis arrived to investigate Krillin’s power and convey Zeno’s wishes, Krillin opened his own passage to the World of Void to confront the flaws in its order.
