Morley is a very hairy and portly giant. He has a Fu Manchu mustache and a shaggy chinstrap beard. He wears very little clothing, only wearing a short plaid skirt in addition to belts around his arms, a flower symbol on his left forearm, dark gloves, a dark bowler hat with frilly goggles on it, and a weapons pack.Belo Betty describes him as looking like a "potato giant".
As an okama, Morley speaks in a very polite and feminine manner. He usually has a very jovial attitude and dislikes those who are unnecessarily violent. When he sees people paying attention to him, he constantly wonders if it is because they have a crush on him, not knowing why they would do so otherwise. However, he does not seem too fond of others being attracted to him, having been grossed out when Betty jokingly implied that the men of the Pinkbeard Pirates had a crush on him.
As a giant, Morley possesses tremendous physical strength and a longer lifespan when compared to humans. Because of his size, he is able to move very large sections of the ground with his Devil Fruit power.
Morley has seemingly eaten a Paramecia-type Devil Fruit that allows him to manipulate the ground he touches like clay. Using this power, he can easily move underground, as well as attack enemies by pushing clumps of ground onto them, as it seems to otherwise maintain its original weight and hardness.
