Appearance

Gohan's appearance changes drastically through Dragon Ball Z, due to the fact that the series starts out with him as a child and ends when he is fully grown. But Gohan's basic physical appearance pretty much stays the same through the course of the series. Gohan has black hair and black eyes, he also has his mother's light peach complexion, rather than his father's light tan.

When Gohan is first introduced, he wears a child's outfit with his family name, 'Son' written on the front, and his hat has the Four-Star Dragon Ball attached to it, the same Dragon Ball in which Goku believed that his grandpa's spirit resided.

While training with Piccolo, he wears an outfit similar to Goku's original, with the 'Ma' symbol King Piccolo wore. After training with Piccolo he has a mullet-type haircut and dons similar attire to the Namek warrior which he continues to wear until the end of the Captain Ginyu Saga, after which he wears Saiyan-style armor given to him by Vegeta. By the Cell Saga tournament he still wears the Piccolo-styled clothing, though his hair is styled in a more wild way due to it being self-cut. While training in the Hyperbolic Time Chamber, he begins wearing Saiyan training gear but again reverts to Piccolo's clothing before facing Cell.

As a teenager he alternates between a school uniform, his Great Saiyaman costume, the Piccolo clothing (except larger in size), a replica of the gi his father Goku wore while he was alive, prior to the Majin Buu Saga, and the Kai clothing given to him by Kibito. His hair is much shorter and stands on end in a spiky formation.

In Dragon Ball GT he is usually seen dressed as like a professor or a businessman, in a suit and a tie. He also wears eyeglasses, even though he shows no sign of actually needing them, due to the fact that he doesn't need them to fight. It is possible, however, that these are reading glasses of some kind, as opposed to general corrective glasses. When facing Omega Shenron, Gohan wears a gi resembling that of the ones Goku used to wear.
