Carbon Costume

In Undertale, Alphys is the scientist who helps Frisk find her way through the Underground. She’s a dinosaur-like monster who loves anime (and Undyne) and she’s very shy and doesn’t have much confidence in herself. She usually wears glasses and a lab coat, but if you wish to cosplay her dating outfit, she wears a black dress with white polka-dots.

In the Netflix original series Daredevil, Elektra Natchios (Elodie Yung) drops in on Daredevil, with whom she clearly has a history. A highly trained assassin, she wields a pair of sais as her trademark weapon.

In Steven Universe, Yellow Pearl is a Gem who works as Yellow Diamond’s receptionist. In the style of her owner, she has a pointy yellow pixie haircut and pale yellow skin. Her gemstone, a yellow pearl, is on her chest and is a round polished cabochon, similar to Blue Diamond’s Pearl.

In Steven Universe, Blue Diamond’s Pearl is a Gem who appears in “The Answer”. Physically, she appears almost identical to the Crystal Gem Pearl and Yellow Diamond’s Pearl, as she also possesses a thin, tall build and a pointed nose and pixie hair-cut. In the fashion of her owner, Blue Diamond, her eyes are covered by her bangs while her gem, a powder-blue pearl, is on her chest.

In Steven Universe, Blue Diamond was once the supervisor of the colonization of Earth before abandoning it after the Crystal Gems’ rebellion. In her debut, she had displayed a great intolerance towards insubordination as she intended to break Ruby’s gem, despite the latter fulfilling her duties and protecting Sapphire.

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 Undertale, Undyne is a fish-like monster that leads the Royal Guard. Clad in her full armor, she pursues the protagonist through the entirety of Waterfall, frequently evaded or inadvertently thwarted by the Monster Kid. She has blue scales and a long bright red ponytail. She has red and blue fins on the side of her head, and a pair of sharp yellow protruding teeth. She wears bright red eye shadow and has an eyepatch on her left eye. Her eyes have vertical black pupils and a yellow sclera.
