Disclaimer: If I owned Pokémon, only amniotes would have any business laying shelled eggs. But I don't!
#401 Kricketot
It is very weak, making it easy prey for many creatures. However, its music stirs all nearby insects to fight against its attackers, making escaping after the meal a more difficult proposition.
#402 Kricketune
It is found in the shadows under giant fungi. It saws off human limbs with its arms and uses them like violin bows.
#403 Shinx
Although it is a wild cub, its behavior is reminiscent of domestic cats. It plays with the heads of its prey like a Glameow would balls of string.
#404 Luxio
An adolescent lion with the capacity to generate electricity. Males are permitted to form their own pride once they have successfully hunted a human.
#405 Luxray
It possesses genuine x-ray vision, which both locates and cripples prey with radiation. If it sees a person with no concealed weapons, it strikes.
#406 Budew
It leaks a fragrant liquid just before it matures into a flower. Because this essential oil is prized by humans, few live long enough to bloom.
#407 Roserade
Its two flower clusters contain entactogens that have potent effects on humans. One promotes loving feelings, the other hateful ones.
#408 Cranidos
A Cretaceous dinosaur that often launched itself off of cliffs during its blind charges. Unlike Bagon, it rarely survived.
#409 Rampardos
They would head butt each other in contests of strength- nearly all skulls fossils found indicate death by concussion. They will attempt to establish dominance over their Trainers by similar means.
#410 Shieldon
After its successful cloning, it was subjected to many experiments concerning its durable armor. It was determined that it was unable to resist the force of a ten-ton block of cement falling on its head.
#411 Bastiodon
Its armor made it nearly impregnable but also very slow. As a result, it often died in massive groups, buried by mud, sand or water.
#412 Burmy
It forms a cloak to conceal its soft body. It is boiled alive so the cocoon can be harvested to make beautiful silk.
#413 Wormadam
A stealthy parasitic worm with advanced sensory ability. It hides in bouquets to locate a suitable human host.
#414 Mothim
Its chromatophores allow it to blend in perfectly with its surroundings. People do not usually notice it until its retractable proboscis has bored into their bodies.
#415 Combee
It was born of an unfertilized egg. It has no brain and acts only in response to telepathic instructions from its Vespiquen mother.
#416 Vespiquen
If it raises too many grubs in its body, they will run out of royal jelly and begin to eat its insides. Its honey is toxic to humans but powerfully addictive.
#417 Pachirisu
One hungry Pachirisu nibbling an apple is adorable. One hundred are nightmarish.
#418 Buizel
A keystone species that preserves kelp forests by keeping the urchin population under control. If you touch its rotating tails your hand will be chopped off.
#419 Floatzel
Often compared to the wolf, it hunts in highly coordinated packs in the sea. It inflates its flotation sack to carry people off before dismembering them.
#420 Cherubi
Its sweet body is nutritious and delicious. It is a popular ice cream topping.
#421 Cherrim
It generally exhibits strong photonasty. However, those which first bloomed during wartime will never reopen, even in the strongest sunlight.
#422 Shellos
Be careful where you step in shallow seas. If a Shellos latches onto your foot, it will stick on so tightly it will require amputation to remove.
#423 Gastrodon
It ingests other toxic species such as Tentacool to enhance its own defenses. It lays eggs in beautiful ribbons, but those who touch the ethereal fibers do so at their own peril.
#424 Ambipom
Its two tails end in clawlike protrusions. It can use them to easily pick any lock and enter a house.
#425 Drifloon
The spirits of lunatics trapped in balloons. They form flocks and hover just over the edge of cliffs, whispering to children to grab them.
