Future Gohan (未み来らいの孫そん悟ご飯はん, Mirai no Son Gohan) is the alternate timeline counterpart of Gohan that appears in the timeline in which Future Trunks lives

Like Gohan's present counterpart's personality as a child, in his childhood, he had lacked the fighting spirit of his father and as a fighter, he is mostly a coward and is a shy little boy, was gentle of heart, a pacifist in nature, but when enraged for seeing his friends hurt, his hidden dormant potential briefly revealed itself, he was also intensely focused in his studies until the time his father had died of the heart virus and the invasion of the androids and the murder of his friends especially his mentor, Future Piccolo which is the period of the time divergence and the period that dramatically changed him for the rest of his life. 13 years after the death of the Z Fighters due to the apocalyptic world that he spent the latter half of his life in, a now adult Gohan is shown being far more serious and aggressive than his present timeline counterpart as a teen and adult who was quite naive, awkward, and is more laid-back and comical especially when donning his Great Saiyaman outfit. Future Gohan seemed to have lost his pacifist-like demeanor which he had as a child and is shown to be in quite a bit of pain, and stress after all the years of challenging the androids alone and has a sort of "do or die" attitude, fiercely driven to destroy the Androids for all the death and destruction they caused.

But as seen in Gohan's brief moments of peace, he does retain his calm and cheerful nature, much like his father and present counterpart. During which, he enjoys life for what it is worth, most notably when telling Trunks to forget about becoming a Super Saiyan until he knows he is ready. Gohan also is incredibly close to Trunks and appears to even consider him as his little brother. Although he had once shared the same dream as his mainstream counterpart of becoming a scholar due to the apocalyptic event that had took place, Gohan presumably never went to school to fulfill that dream. It is assumed that he had spent all of his time training and pondering ways to stop the Androids. Gohan had said to Bulma that he always dreamed of being strong like his father. Also, despite his aggressiveness, he was prepared to acknowledge his chances against the androids were low and that he would entrust Trunks as the last defender of Earth.

Although, under the microscope and inspecting his personality more, you can say that Gohan is somewhat unstable, as soon as the first drop in the fight he can give up very easily, Gohan relies heavily on his father, which slowly led him to the abyss, being compared more than once to his own father and how "Goku could easily take down the androids."

From the beginning, Gohan wanted to finish it all, but he couldn't do it thanks to Trunks. However, the final battle was approaching, the moment where Gohan could rest or give it his all until the end.

Even so, Gohan is a noble person, treats everyone with care and respect, despite the few survivors.
