Son Goten Xeno is an alternate-timeline version of Son Goten from a world distinct from the main Dragon Ball continuity. His history mirrors his primary counterpart, including events from Dragon Ball GT. Recruited by Chronoa, the Supreme Kai of Time, he serves in the Time Patrol to defend history against temporal threats. His initial appearance features informal martial arts attire reminiscent of World War II-era clothing: a black trench coat, reddish-brown gloves, olive green pants with lighter-colored bandages around the shins, and brown laced boots. Later, during the Demigra Assault Saga, he adopts an outfit similar to his father, Xeno Goku: a long-sleeved shirt, a flowing red vest with a long back, an olive green obi tied at the waist, armbands, while retaining the same pants and boots. Personality-wise, he retains his GT counterpart's flirtatious, kind-hearted, and considerate nature. He maintains strong camaraderie with Xeno Trunks, reflecting his original timeline's friendship. His Time Patrol duties contribute to a slightly more mature demeanor compared to his main counterpart. His Time Patrol chronology begins in the Dark Demon Realm Saga, assisting Super Saiyan 4 Goku, Xeno Trunks, Beat, and Note against Baby Hatchiyack. During this mission, he performs the Fusion Dance with Xeno Trunks to become Xeno Gotenks. In the Dark Empire Saga, he battles Mechikabura's forces in the Demon Realm; after fusing into Xeno Gotenks to repel soldiers, he separates to confront Xeno Dabura individually while Xeno Trunks aids Chronoa. The Dark King Mechikabura Saga sees his potential unlocked by Old Kai, enhancing his combat abilities. He battles the Xeno Shadow Dragons and later confronts Dabura in his second Demon God form, defeating him off-panel. During Mechikabura's assault, he sustains severe injuries and contributes energy to Xeno Trunks, enabling Trunks' transformation into Super Saiyan God and the subsequent sealing of Mechikabura. In the Universe Creation Saga, he and Xeno Gohan are captured by Mira; Towa extracts dark energy absorbed during Mechikabura's defeat to empower Fu. During the Supreme Kai of Time Saga, he teams with Xeno Trunks, facing Tapion in a tournament context. Later, alongside Xeno Pan and an alternate Majuub, he assists against Transcended villains, combating Super Android 13 in his base form. In the Demon Invader Saga, he helps rescue Chronoa from Majin Ozotto by allowing himself to be consumed, creating an opening for Xeno Trunks to strike with the Key Sword. His power level is comparable to Xeno Trunks in base form, enabling consistent fusion. As a Super Saiyan, he dodges attacks from the injured Demon God Shroom and overpowers adversaries like Lord Slug and Bojack. His abilities include flight, energy blasts, Kamehameha, EX Dragon Fist, and Dragon Claw Dance. He also utilizes specialized techniques like "Freeze," manipulating time to immobilize opponents, and "Shenron: Wish of Strength," summoning Shenron via the Dragon Balls. His transformations include Super Saiyan and Potential Unleashed, unlocked via Old Kai's ritual. His primary fusion remains Xeno Gotenks through the Fusion Dance.
