Gems are an extraterrestrial species of "magical" beings that play a key role in Steven Universe. 5,750 years ago, the Gem Homeworld maintained several outposts on Earth, with plans to completely colonize the planet, but were driven off by Rose Quartz's rebellion, leaving the Crystal Gems (and various Corrupted Gems) the only Gems on the planet

Power Source: Resources from the planets they conquered
Industrial Capacity: Massive, Gems see Country level weapons as extremely outdated, have technology which can hollow planets and basic weapons which can casually immobilize Multi-Continent level opponent, as well as Multi-Continent level items. Gems also created The Cluster, which is powerful enough to destroy entire planets.
Military Prowess: Gigantic, each planet conquered by Homeworld is used for the creation of thousands of different Gems.
Weaknesses: Enough damage to their physical form will make them retreat inside their Gems. Can't regenerate their Gems, and will die if they are destroyed.
