Gem Views on Fusion... and stuff (warning for mentions of manipulation and coercion)
Black Opal -- uses it to manipulate other Gems, viewing fusion like some view sex. They see it as a means to an end and a way to trap others and hold control over them. They’re seductive and coercive, promising intimacy and understanding that does not come inherently to Gem culture. But all they really want is additional power and, on a superficial level, to be a beautiful giant nb gay rock the likes of which the universe hasn’t seen. Black Opal is toxic to fuse with, whether over time or through multiple fusions. The initial fusion is humanoid but becomes more monstrous with each iteration. Their personality usually has the stronger influence on the resulting fusion because of their hypnotic abilities... that and they’re a high-maintenance, demanding jerkface.
Blue Lace Agate -- initially held Homeworld’s viewpoint but changed her mind after having to fuse with a different type of Quartz out of necessity. Her telepathic abilities made the experience more intimate than she bargained for. Blue became more curious about it after that but did not have the opportunity to fuse again until she defected from Homeworld and became marooned on Earth. She found the experience just as strange but extremely pleasant, and hopes to get a better understanding of the emotional complexity and closeness that fusion can bring.
Blue Sandstone -- has never fused and has little reason to because vir role as a scout often has vir working alone. Vi has witnessed the emotional side of fusion and as a result, vi finds fusion both interesting and intimidating. Blue Sandstone is often lonely and wishes to have more interactions with other Gems. Vi fantasizes about fusing but never shares these thoughts with others, too afraid of the consequences... whether it be rejection, harm to vir person, or someone actually offering to fuse with vir.
Magnetite -- held no opinion on it before she hooked up with Black Opal. The intimacy and rush of power excited her. She became addicted to it, enjoying the feeling of being herself, being someone else, and being something completely and utterly new. It was common for her to search out fusion partners while she was still whole. She was just as seductive about fusion as her former compatriot, though much less manipulative. To her, it was a fun way to spend some time than anything serious. Now that she is broken, it is unclear if her addiction to fusion remains. She is far more concerned with revenge during the brief periods of time she makes a reappearance.
The Twins -- don’t understand fusion. They get the basic concept of it but the complicated nature of it eludes them. Thankfully the Twins have not retained Magnetite’s addiction to fusing because they cannot remember being her. The Twins’ fusions have largely been instinctual. Though they don’t get along, they often feel a strong desire to be with each other anyway. It’s common for them to fuse together without thinking, and at times, it seems like they’re doing so in a trance. As stated before, when the Twins fuse they form the original Magnetite. But they can’t retain her form for long because of the physical damage to her gem. It is unknown whether they can fuse with other Gems... though if it is possible, there’s a possibility the fusion might be corrupt.
