GoodBros Archive No. 0001264
In Galar, Shellder's bite causes a different chemical reaction in the brain due to the Galarica spices that make up Galarian Slowpoke's diet, causing Galarian Slowking to take on a unique appearance. The tip of its tail and the top half of its body are purple, and it has a long dark cloak that drapes from its neck. The Shellder has grown more dominant, appearing completely different with a rougher texture, a darker gray coloration, and a larger size, covering Slowking's eyes and nostrils. It has several purple spots dotting it, with a large one at the center that surrounds a green gem and two black eyes. The spikes on the Shellder are more blunt, and it has two purple horn-like tubes on either side from which poison may be secreted. The Shellder's teeth have also grown in size and are broad and flat instead of sharp; the same holds true for its wearer.
As Galarian Slowking evolves, the Shellder on its head has its intelligence skyrocket, giving it the ability to control the Slowking, as well as psychic powers that can rival the power of other Psychic-type Pokémon. Galarian Slowking has been observed chanting mysterious spells and incantations in battle or to communicate with each other. It also chants these spells while creating strange potions using its internal toxins. What these incantations and spells mean has yet to be fully understood.[3] Galarian Slowking is capable of creating potions by mixing toxins it produces with the food it consumes. These potions are derived and secreted from poison and the holes on Galarian Slowking's horns. However, not even Galarian Slowking itself will have any idea what effects the potions it produces will have. It will administer the potions it creates to weaken any Pokémon it sees fit to test on. They can also be found in the Coastal Biome of Blueberry Academy's Terarium, where Galar's regional life is simulated. As seen in An Evolution in Taste!, Galarian Slowking's Shellder crown retains the same ability to control humans like its Johto counterpart.
Galarian Slowking is the only known Pokémon capable of learning the move Eerie Spell, as well as the only known Pokémon that can have Curious Medicine as its Ability.
