Son Gohan Xeno originates from a timeline distinct from the primary Dragon Ball continuity. He serves as a member of the Time Patrol, dedicated to preserving historical integrity across dimensions. His personal history parallels his main counterpart's experiences in the Frieza and Cell Sagas but diverges by incorporating elements from non-canonical films and Dragon Ball GT. His background includes events from the Dead Zone, Lord Slug, Bojack Unbound, and Fusion Reborn movies, plus the battle against the Shadow Dragons from Dragon Ball GT. He never participated in the Dragon Ball Super storyline. His appearance evolves across story arcs. During the Dark Demon Realm Saga, he wears martial arts attire with a World War I/II aesthetic: a basque green trench coat, glasses, red gloves, olive green pants with light shin bandages, and brown laced boots, sporting his Majin Buu Saga hairstyle. In later arcs like the Demigra Assault Saga, his attire reflects scholarly pursuits: a grey button-up shirt, black vest, maroon necktie, gloves, and traditional olive drab martial arts pants secured with a yellow sash. Personality-wise, Son Gohan Xeno mirrors his main counterpart's gentle yet protective nature, especially toward his daughter, Xeno Pan. He exhibits heightened overprotectiveness and strictness regarding her involvement with the Time Patrol, openly opposing her participation due to the lethal dangers involved, echoing concerns similar to Chi-Chi's. This profound desire to shield Pan serves as a critical emotional catalyst, triggering his transformation into Super Saiyan 4 during a life-threatening confrontation with Demon God Shroom. His major conflicts begin with the Dark Empire Saga, summoned by Chronoa to reinforce Time Patrollers. Alongside Xeno Trunks in Age 762, he confronts Xeno Slug, merged with a Six-Star Dark Dragon Ball. He exploits Slug's heightened auditory sensitivity with a sharp whistle, echoing his past encounter with Lord Slug. When Dark Demon God Buu (absorbing Xeno Janemba) and Towa's dark magic empower Slug, Son Gohan Xeno and Xeno Trunks fuse into Xeno Gohanks, struggling against the augmented foe. During the Dark King Mechikabura Saga, Robelu helps him unlock new power in Age 790. Using a Blutz Wave Generator, she triggers his Great Ape transformation, which refines into Super Saiyan 4. This new form allows him to join Xeno Gogeta against Fin, delivering a decisive energy blast. Later, navigating Hell Gates to dismantle barriers protecting Mechikabura's palace, he encounters Demon God Shroom. After dismissing Pan for safety, he is poisoned by Shroom's scythe. Pan's return and encouragement reignite his resolve, enabling the Super Saiyan 4 transformation to defeat Shroom with a Kamehameha, though he collapses afterward. Severely injured during Mechikabura's final assault, he contributes his remaining energy to empower Xeno Trunks, facilitating Trunks' ascension to Super Saiyan God and Mechikabura's sealing. He participates in additional conflicts. During the Universe Creation Saga, he and Xeno Goten are captured by Mira; Towa extracts the "Dark Factor" from them to empower Fu. In the New Space-Time War Saga, he recovers at the Time Nest under Pan's care. Later, in the Supreme Kai of Time Saga, he competes in the Super Space-Time Tournament. On Planet Glass, he shields Pan from Vidro's glass-encasing attack, sacrificing himself to protect her. Freed later, he battles Demigra's summoned warriors, including Medamatcha. His combat abilities include multiple transformative states. Once attained, his Super Saiyan 4 form is accessible at will, exhibiting overflowing magenta ki, crimson-red highlights with dark shadows, and a deepened, calmer voice. Deployment is limited due to potential temporal instability risks. He also achieves the "Potential Unleashed" state, referenced in card listings UM3-026 and BM4-051. He performs fusion techniques, notably merging with Xeno Trunks to form Super Saiyan 3 Xeno Gohanks against threats like Xeno Omega Shenron.
