Powers and abilities
As a human, Smoke had the ability to emit smoke, most commonly seen as the smoky fumes that his human forms emit. He still seems to retain this ability in his cyborg form, though he doesn't seem to use it much. Smoke usually uses this ability to disappear or create a cloud of fumes that his opponent chokes on, making them open to an attack. After becoming a nanotech based cyborg, his body appears to be made of smoke or nanites emulating the appearance of smoke. Smoke also gained the ability to transform others into shadow warriors by flowing his gaseous mist into them.
