Monster Steven is the final antagonist of Steven Universe Future, the epilogue/time-skip to the original Steven Universe series on Cartoon Network. Monster Steven is the form taken on by Steven Quartz Universe at the end of the third to last episode of the series wherein he has a mental breakdown regarding his increasingly unstable mental state as a byproduct of the things that he has experienced during the previous series and his various sins throughout the epilogue series.

He concludes that his whole shtick is that he keeps messing up, making things worse, and hurting people and as a result always has to fix his mistakes, maintaining a fraudulent angelic perception by his peers and never being able to grow or improve himself as a person and more often making himself worse with the stress, guilt, and frustration. Because of this, he ultimately concludes that he is a fraud and a monster (just like his mother: Pink Diamond, a.k.a. Rose Quartz).

Due to Steven's highly unstable shapeshifting abilities linked to his emotional state, Steven transformed into a literal giant monster or kaiju and displaying behavior similar to that of a Corrupted Gem. He is massive in size, towering over the Crystal Temple and completely dwarfing the Diamonds, though he noticeably decreases in size over time, becoming only a few meters taller than his fellow Diamonds. His posture is heavily hunched over and his anatomy is disproportionate, with a potbelly, a long heavy neck ending in a small head, a short tail, long powerful arms, and relatively short legs. His body is covered head to toe in hot pink tuberculate scales that are hexagonal in shape, and his back is protected by a thick armored carapace. He has numerous pinkish off-white thorn-like spines running down the length of his back and forearms, starting at his forehead and ending halfway down his tail. He retains his human form's facial profile and nose, though his eyes have gained black sclera and glowing pink pupils, and his mouth is now jagged and filled with sharp teeth. On the sides of his head are a pair of long, angular horns that point upwards, as well as a similar-looking pair of short, curved tusks on the sides of his lower jaw. His forearms are thick and powerful, bearing large human-like hands with four fingers and a thumb each, all five digits bearing sharp, dark pink claws. His legs are digitigrade in posture and his feet bear five claw-tipped toes each. His gemstone is still located where his navel would be, though it appears much smaller due to his massive size in this state.

Matching his size, Monster Steven is easily the most powerful character in the series, being able to easily defeat The Crystal Gems while they're fused together as Alexandrite, the Back-Up Crystal Gems consisting of Peridot, Bismuth, and even the god-like Lapis Lazuli; All three Diamonds, Spinel, The Galactic Geo-Weapon known as The Cluster, Connie Maheswaran, and Greg Universe at the same time.
