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 that also cost him his left arm.

He never changed his hairstyle since his childhood, but the longer part of his hair is cut much shorter, somewhat resembling the haircut his alternate past counterpart had when he first trained in the Hyperbolic Time Chamber, and when fighting with Cell, only it was more grown into (because Future Gohan was a full-grown adult). Bulma even states that Gohan looked strikingly similar to Goku when wearing this uniform. 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 top to bottom, and he also wears his own kanji symbol on the back, Han, 飯. He also dons a uniform greatly resembling that of Goku's early uniform, and states that he is inspired to wear it in the hopes that he will one day be as strong as he was. Future Gohan before acquiring his facial scarįuture Gohan appears as a tall, stern, and muscular man.
