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 escapes from an evil scroll and possesses Steven's Together Breakfast. Gaining all the powers of a breakfast, it pins down the Gems, breaks Pearl's spear, and almost defeats them, until Steven destroys 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 is destroyed soon after creation.
- It was revealed by Joe Johnston on Tumblr that the Gems responsible for the smoke monster are ground up and used for pigments in the ink on the burned scroll: "Well, to make pigments you use certain minerals to achieve different colors. Those different pigments get use in inks and paints... see where I’m going with this...". The post was later deleted.
