The "Smoke Monster" was a monster that Garnet was trying to destroy in the episode "Together Breakfast", until Steven distracted her. The Smoke Monster's power comes from the crushed Gems used as the scroll's pigments.
It escaped from an evil scroll and possessed Steven's Together Breakfast. Gaining all the powers of a breakfast, it pinned down the Gems, broke Pearl's spear, and almost defeated them, until Steven destroyed it along with the breakfast.
- The Smoke Monster resembles Giygas from the Super Nintendo RPG, Earthbound. (Or Mother 2 in Japan.)
- It is unknown how long the smoke would last without a corporeal host, as it was destroyed soon after creation.
- It was revealed by Joe Johnston on Tumblr that the Gems responsible for the smoke monster were ground up and used for pigments in the ink on the burned scroll.
- Despite being crushed to dust, the magic in these Gems allowed them to remain functioning on some level, similarly to broken Gem Shards.
- Furthermore, they remained conscious, proven by the audible screams once the scroll was set ablaze.
