Future Gohan appears as a tall, stern, and muscular man (considerably more so than the appearance of his main timeline counterpart during the Majin Buusaga ). He also dons a uniform greatly resembling that of Goku's early uniform, and states that he is inspired to wear his "dad's old colors" in the hopes that he will one day be as strong as he was. The only differences between his uniform and Goku's is that the sleeves are longer on his, his boots are a dark blue with yellowish stripes on the bottom edges and without the line running in the middle of the boots from to top to bottom, and he also wears his own kanji symbol on the back, Bulma even states that Gohan looked strikingly similar to Goku when wearing this uniform. His hair is cut much shorter, somewhat resembling the haircut his alternate past counterpart had when fighting with Cell, only it was more grown into (because Future Gohan was a full-grown adult). He also obtains a scar that runs down the left side of his face, the after effect of an injury sustained during a battle with the androids. Later on, in a battle against the Androids he loses his left arm trying to protect Trunks.
Future Gohan's power level is not as strong as the main timeline's Gohan due to him being the only Z-Fighter remaining, and therefore unable to train with anyone. He is also able to put up a good fight against Future 17 or Future 18, however he is completely unable to put up even a reasonable fight against both of the Androids
