Scykution evolves from Guilade when exposed to a Shiny Stone.
Scykution continues from its pre-evolution appearing to have a somewhat monstrous appearance, in this case appearing somewhat akin to a banshee, the Pokémon has long claws in the place of its fingers and its legs are completely obscured by its long silver hair which appears to be made of metal as the Pokémon is able to protect itself from oncoming attacks by hiding within its own hair. Its arms are considerably more muscular in shape being more well-defined but also have prominent bone structures giving them an anemic appearance. The Pokémon's face remains mostly obscured again although its eye is now red and dark magenta, in addition its mouth can be seen more clearly in Scykution and shows the Pokémon has no lips and bare fangs across its entire jaw giving it an unsettling grin.
The Pokémon's metallic rings remain from its pre-evolution although the ones on its wrists, neck and ankles are now connected by chains which swing in its idle animations and will shake when the Pokémon uses certain attacks, it appears to have some sort of psychic control over the chains as they can be seen faintly glowing from time to time. Scykution's tail is larger and longer than its pre-evolution, coiling around similar to a snake, the tail is covered in dozens of spines aligned in pairs that all face upwards. The tail is segmented by a number of metallic rings with one on the end of its tail once again. Its tail tip appears as a full scythe blade forming a slightly lightning-bolt shape.
