In Steven Universe, Sugilite is the fusion of Amethyst and Garnet (and by extension, Ruby and Sapphire). Sugilite is colossal fusion with a stocky build, with four arms (each pair seeming to share a shoulder joint). Her mouth is twisted into a grin and filled with sharp, pointed teeth. She has a giant plume of spiky, dark purple-black hair kept in an untamed style similar to Amethyst’s, but messier.

In Steven Universe, Sardonyx is the fusion of Pearl and Garnet (and by extension, Ruby and Sapphire). Sardonyx towers in size, she’s so tall that her hands are actually taller than Steven. She has vermillion skin and pale peach/apricot-colored hair, styled into a tetrahedron with very rounded corners. Her torso and legs greatly resemble Garnet’s, but have less mass. As a fusion, she has four arms and inherits the same locations of her gemstones as her fused cooperators.

In Steven Universe, Jasper, once the superior of Peridot and Lapis Lazuli, is one of the most formidable antagonists. She is serious and headstrong, with a fierce hatred for the concept of fusion, until she goes on to fuse with Lapis.

Tiger Millionaire is Steven Universe’s wrestling alter ego. He wrestles tag team with Purple Puma and often uses props like a briefcase full of money or a gigantic cell phone to take out his opponents.
