The Homeworld Gems, also known as The Homeworld, are the original group of gems who came to and exploited Earth, causing the Crystal Gems to splinter and oppose them. They were first alluded in the episode, "Serious Steven" and mentioned in the episode, "Mirror Gem". They serve as the main antagonists of the Cartoon Network TV series Steven Universe.
Before Steven Universe
6,000 years before the events of the series, gems came to Earth and spread their influence to it, creating gem landmarks and monuments. One of these landmarks was the Kindergarten, a "breeding ground" for creating gems. In an unknown amount of time later, it was shut down by Rose Quartz and her followers. 1,000 years later, a war had started between Homeworld and Crystal Gems, resulting in a victory for the latter. The Homeworld Gems then returned to their world and, over the course of 5,000 years, developed advanced technology like gem destabilizers and improved gem warships for their second attempt to take control of Earth.
After thousands of years, the Homeworld Gems send a scout drone called a "Red Eye" to Earth to detect gems but was promptly destroyed by the Crystal Gems, without reporting any activity. After that, they send Peridot and her 79 Flask Robonoids to repair Earth's Homeworld Warp, only to have her leave, resulting in the Homeworld Warp being destroyed by Garnet. They again send Peridot and her Plug Robonoids to the Kindergarten to reactivate it, only to be thwarted once again by the Crystal Gems. However, Peridot did return with knowledge of Earth-resident gems. In response to the Crystal Gems, they send Peridot, Lapis Lazuli, and Jasper on a mission to capture the Crystal Gems. In the process, they discover that Steven has Rose Quartz' power, and decide to bring him to their supposed superior, Yellow Diamond. Later on the Gem Warship, Peridot mentions that they needed to find an entity called, "The Cluster". The Crystal Gems manage to escape, destroying the warship and sending it and everyone aboard crashing beside the Crystal Temple, with the exception of Peridot who was ejected somewhere on Earth's surface prior to the warship's entry into Earth's atmosphere. Back at the crash site, the Crystal Gems manage to survive the crash, but suddenly, Jasper emerges from the rubble, weak and exhausted until she sees Lapis Lazuli and convinces her to fuse with Jasper, forming Malachite, only to have Lapis take control of the whole fusion dragging herself and Jasper to the bottom of the ocean. In the aftermath, the Crystal Gems celebrate, but Greg brings up the possibility of more Homeworld Gems retaliating, meaning their fued with the Homeworld isn't over yet.
Steven and the Cool Kids accidentally discover Peridot's damaged escape pod in a crop field. When they investigate it, Peridot had already left with her whereabouts left unknown. In an attempt to find her, the Crystal Gems travel to the Kindergarten. Steven discovers Peridot leaving Facet Five of the Kindergarten, causing the other gems to chase her. Peridot uses her fingers like helicopter blades to fly away with Pearl and Amethyst in pursuit. Meanwhile, Steven and Garnet enter Facet Five and find fused gem shard limbs, and the Cluster, a forced fusion of gem shards combined into a gem monster, as a form of punishment for the fallen soldiers of Rose Quartz's rebellion. Garnet defeats the monster, and Peridot escapes. Peridot was then eventually captured by the Crystal Gems, while she was interrogated about living the earth, she had given the full details about her mission. Peridot had revealed that Earth is no longer a colony and became a base for a series of artificial gem fusions to create the biggest forced fusion comprised of millions of gem shards.
Season 3In "Super Watermelon Island", using his astral projection ability, Steven discovers that Malachite is attacking mask island, forcing the gems to warp there and form Alexandrite in order to stop her. With the help of the Watermelon Stevens, Alexandrite manages to defeat Malachite, but can only manage to save Lapis when the cluster starts emerging and ruptures the island, knocking Jasper into the ocean. In "Same Old World", Lapis reveals that the Homeworld gems were the ones that trapped her in a mirror, confusing her for a crystal gem, and cracked her during their escape. In "Barn Mates" a Homeworld scout ship comes to the barn, supposedly looking for Peridot, before being taken down by Lapis. At the end of the episode a Ruby pops out of the wrecked ship. In "Hit the Diamond", four other Rubies come out of the ship, still supposedly looking for Peridot. The team is infiltrated by the Crystal Gem's Ruby, who fails to lead the other Rubies away from the barn, before Steven convinces the other Rubies that they have to play baseball in order to be allowed entrance. The Crystal Gems (disguised as humans) beat the Rubies at the game, until an overjoyed Ruby and Sapphire accidentally fuse into Garnet, blowing their cover. The Rubies fuse into a giant version of themselves, intent on destroying the gems, until Peridot tries to reason with them resulting in the Rubies revealing that they were actually looking for Jasper and being tricked into looking for her on Neptune by Steven. In "Monster Reunion", Centipetle reveals that she was corrupted by a giant flash of light and blames the Diamonds for that. In "Alone at Sea", Jasper shows up on Greg's boat, begging Lapis to re-fuse with her. When she refuses, she attempts to attack Steven, only to be flung away by Lapis. In "Gem Hunt", Jasper shows up at the end, poofing and capturing the monster Steven and Connie were fighting and walking away after taunting "Rose." In "Crack the Whip" Jasper showed up with the two monsters she captured and uses them to attack Amethyst, Steven, Connie and Lion. Jasper brutally beats Amethyst, taunting her about how she is defective and weak, before being driven off by Stevonnie. In "Beta", Peridot attempts to cheer Amethyst up by taking her to Jasper's birthplace, the Beta Kindergarten, a hastily rushed and poor version of Amethyst's kindergarten made to quickly pump out gem solders during the war, to show her how poorly Jasper was made, until realizing that she is literally the perfect Jasper solder. In "Earthlings", after briefly spotting her, Steven, Amethyst and Peridot discover that Jasper has been capturing and imprisoning corrupt gems in an attempt to make an army. After a short fight, Amethyst realizes that she cannot defeat Jasper and accidentally fuses with Steven to create Smoky Quartz, who easily defeats Jasper, even when she fuses with a corrupt gem. Slowly being corrupted, Jasper refuses help from Steven and reveals that Rose Quartz did something horrible to Pink Diamond. In "Back to the Moon", the Rubies return to Earth still intent on finding Jasper, only to be tricked by Amethyst, who shape-shifts to look like Jasper. Being fooled by the Gems, the Rubies take them to the moon base in order to contact Yellow Diamond, going through the history of the diamonds and revealing that Pink Diamond was in charge of Earth and that Rose Quartz had shattered her. After discovering the facade, the Rubies fuse, only to be knocked out the air lock by Sardonix and Steven, accidentally taking Steven with them. In "Bubbled", Steven floats around in space with Eyeball Ruby, who tries to kill him when she finds out that he has Rose's gem, only to be thrown into space.
