Steven Universe`s Guide to the Crystal Gems for Humans

Gem Fusions

A Gem fusion is when two Gems fuse by a sycranizing dance. A fusion combine the two Gem`s personalities and binds them. Some fusions, like Garnet and Sugilite, are stable, which means the two halves are stable, only to be unfused by serious inquiry or if one decides to unfuse. Other fusions, like Opal, are unstable. This means the two halves are constantly fighting due to lack of heart towards each other. Fusions have the same abilities as single Gems, but they are more powerful since the two halves have merged so that all the powers from the single Gems combine.
