X
 It drives away opponents by excreting a sticky liquid that can dissolve anything. Its eyes devolved, so it can’t see anything.
 Y
 Its four horns are a high-performance radar system. It uses them to sense sounds and smells, rather than using ears or a nose.
 Omega Ruby
 It drives away opponents by excreting a sticky liquid that can dissolve anything. Its eyes devolved, so it can’t see anything.
 Alpha Sapphire
 Its four horns are a high-performance radar system. It uses them to sense sounds and smells, rather than using ears or a nose.
 Sun
 It has trouble drawing a line between friends and food. It will calmly try to melt and eat even those it gets along well with.
 Moon
 This Pokémon’s mucous can dissolve anything. Toothless, it sprays mucous on its prey. Once they’re nicely dissolved, it slurps them up.
 Ultra Sun
 It crawls along sluggishly. The swirly protrusion on its back is filled with its brain and other organs.
 Ultra Moon
 Its entire body is covered with gooey mucus that can dissolve anything. Be sure to put gloves on if you’re going to touch it.
 Sword
 Although this Pokémon isn’t very strong, its body is coated in a caustic slime that can melt through anything, so predators steer clear of it.
 Shield
 The lump on its back contains its tiny brain. It thinks only of food and escaping its enemies.
 Legends Arceus
 A creature given to melancholy. I suspect its metallic shell developed as a result of the mucus on its skin reacting with the iron in Hisui's water.
