Species

The world of Steven Universe is filled with many different creatures. This page will catalog the known species.

Gems
Gems are a humanoid species. The Crystal Gems on Earth are dedicated to the protection of humanity. They have many and varied abilities, but all share the trait of having a magic crystal somewhere on their body from which they can summon a special weapon. They are genderless, Steven is the first gendered Gem because he is half human! It is shown that Gems can survive deep space travel without the need for protective clothing. It is also shown that some gems can control natural elements, as Lapis Lazuli was able to control water. Another notable ability is that some gems can have wings, as Lapis Lazuli was able to form wings. Weither this was a part of her natural appearence or her ability to manipulate water is unknown.
