Goo is an average sized man, with tanned skin and a large chin. He has stubble on his chin, and black hair that is long in the back, with sideburns. He sports a blue tricorne with yellow on the edges. He wears a purple captain coat, with a normal shirt.
Goo was a rational man, telling his crew to stay out of the sunlight in the morning and sleep, to avoid disintegration. He was very happy when his shadow was returned.

Goo was seen wielding a saber.
Two years before the Battle of Marineford, Gecko Moria stole the shadow of Goo and his entire crew during their travel into the Florian Triangle of the Grand Line, rendering them unable to exist in sunlight.
Thriller Bark Arc
While the crew continued their travel down the Grand Line, their shadows returned when Monkey D. Luffy defeated Moria. Goo was awakened by one of his subordinates to this news, and the crew celebrated this.
