Dodds has prophetic dreams which come to him as cryptic, ambiguous visions of crimes. Originally of unexplained origin, these dreams were later ascribed to encounter between Dodds and the entity known as Dream via retcon. The visions haunt Wes, who uses his keen intellect and amateur detective skills to properly interpret them. He is also a talented chemist and inventor, creating the sand-like substance and the Silicoid Gun ultimately responsible for transforming Sandy the Golden Boy into a Silicon-based life-form. In the early years of his career, Wesley Dodds possesses the strength level of a man who engages in regular exercise, and was a fine hand-to-hand combatant. As he grows older, his strength level diminishes in relative proportion to his age. As hobbies, Wes enjoys reading, writing, poetry, origami and philosophy. Through an unknown process, Wes passes his power of prophetic visions on to his former ward, Sanderson Hawkins upon the moment of his own death.  Wesley Dodds' costume consists of a basic green business suit, fedora, a World War I era gas mask, a gas gun, and a wire gun. The gas mask protects Dodds from the effects of the gas emitted from his gas gun. The gas gun, a handheld device fitted with cartridges containing concentrated sleeping gas, is Wesley Dodds' only known weapon. Pressing the trigger on the gun releases a cloud of green dust rendering all within the Sandman's immediate vicinity unconscious. An upgraded canister dispenser for the gun is provided for him by his close friend and confidante, Lee Travis. Wes is also known to conceal smaller knockout gas capsules in a hollow heel on his shoe. These prove ideal when placed in situations where his gas gun is not readily available. He also makes use of a specially designed "wirepoon" gun, which fires a length of thin, steel cable.  In the early days of his career, the Sandman drives a black 1938 Plymouth Coupe. The car is enhanced with various features to aid Wes in his crusade against crime.
