Disclaimer: If I owned Pokémon, Altering Cave would alter. But I don't!

#551 Sandile

The sex of its offspring is determined by the temperature of its eggs. It attacks humans to obtain their jewelry for use as gastroliths to properly digest its food.

#552 Krokorok

It steals treasure from tombs and Gabite hoards in the desert. Its den is littered with the bodies of those who tried to take its gold.

#553 Krookodile

What appear to be markings around its eyes are actually sunglasses it stole from a corpse. If they are removed to reveal its glowing red eyes, it will immediately attack.

#554 Darumakka

A living doll animated by a stray divine spark. It is powerful but inevitably brings bad luck, especially if it was a gift from a loved one.

#555 Darmanitan

Their constant rampages scorched the land and turned once-fertile plains into a barren desert. They were imprisoned in stone statues by the ancients to protect the world from further destruction.

#556 Maractus

The rattling noise it makes is not caused by seeds. Rather, it is the sound of the bones of the carcass it grew around shaking inside its stalk.

#557 Dwebble

Competition for the best makeshift shell is fierce. Although rock is most often used for its availability, Dwebble will become most aggressive in pursuit of human skulls.

#558 Crustle

Through carbon dating, scientists have found that some soil in its slabs is over 120 million years old. It sometimes emerges from the sand on the beach, carrying off sand castles along with their builders.

#559 Scraggy

It is a popular pet among urban youth thanks to a recent government initiative that actually exacerbated the violence it was meant to reduce. Its shed skin radiates dark energy- do not attempt to collect it!

#560 Scrafty

They form gangs in large cities and vandalize buildings. Their wars with rival gangs often result in more casualties among humans in the crossfire than Scrafty themselves.

#561 Sigilyph

It orders Unown to spell out dire warnings to archaeologists. Its body is only visible from far away- if you approach all but its third eye will vanish.

#562 Yamask

If it was a sinful human, it is tormented by its punishment. If it was a righteous human, it is even more haunted by its undeserved fate.

#563 Cofagrigus

An archaeologist unearthed a tomb filled with spectacular treasure, stirring a dormant Cofagrigus in the process. Within months all his friends had died.

#564 Tirtouga

A Cretaceous sea turtle that fed on shellfish in shallow waters. Large beach predators flipped it over onto the sand and ate its insides.

#565 Carracosta

They possessed a skeleton-supported carapace rather than a solid shell. In territorial fights, this protection was often ripped off by blows from powerful fins, tearing off chunks of bone.

#566 Archen

New evidence suggests it was not actually an ancestor of bird Pokémon. Fossils of injured individuals indicate that it often fell off cliffs due to its poor flying ability.

#567 Archeops

An extinct theropod that possessed limited flight capabilities. This lack of aerial prowess has not hindered it, however- it has killed thousands since its misguided resurrection.

#568 Trubbish

An odd Pokémon well adapted to refuse-laden modern cities. However, if it ingests too many artificial flavors and pesticides, it will burst open dead and create a huge mess.

#569 Garbodor

It cannot naturally produce the enzymes it needs to catalyze the formation of the toxins it uses to hunt. Human bodies provide the necessary chemicals for carrying out the reaction.

#570 Zorua

It transforms into a cute, lost-looking child to lead people into misty pine forests. When they are hopelessly lost, it turns back into a fox and abandons them.

#571 Zoroark

Its illusions are so powerful that it can almost flawlessly mimic people's closest friends. This disguise allows it to easily lure them into its dark den.

#572 Minccino

They make poor pets due to their restricted diet of a special type of hay. Most are raised exclusively for slaughter by the fur industry.

#573 Cinccino

Its fur is the height of fashion in Milan. The scarf around its neck is actually a dead animal, often a Furret or Linoone.

#574 Gothita

Due to international child labor laws, they are often used by movie studios to play human babies in lieu of the real thing. They do their own stunts.

#575 Gothorita

A mother drowned her children in a river and became Gothorita. She kidnaps children by the riverside, thinking them her own.
