Disclaimer: If I owned Pokémon, nice Trainers would keep their aquatic species in the water and alive. But I don't!
#201 Unown
They are believed to have been invented by Sumerian mystics but have spread to ruins worldwide. They form groups to spell out warnings about the sinister intentions of dark types.
#202 Wobbuffet
It lurks in sunless caves, relying on hearing rather than sight. Its inflatable body holds no internal organs.
#203 Girafarig
It transmits psychic impulses to immobilize people who enter its territory. Its second head then eats the helpless victim, who retains consciousness during the devouring.
#204 Pineco
Children who mistake it for a pinecone enjoy stripping off pieces of its bark-like shell. It responds by exploding.
#205 Forretress
Its durable steel shell allows it to be farmed for use as a cannonball. However, being employed in this way eventually reduces its shaken innards to jelly.
#206 Dunsparce
Because it is so rare, a large reward was offered for its first capture. The many Dunsparce bodies trampled in the ensuing chaos finally proved its existence.
#207 Gligar
A bizarre hybrid of bat and scorpion that demonstrated the unbelievable advances of genetic engineering. Several of the test organisms escaped and formed a colony in the place now called "Death Canyon."
#208 Steelix
The extreme pressure it experienced underground hardened its body and thoroughly enraged it. As soon as it is freed, it will go on a rampage- this is what destroyed an early settlement on Iron Island.
#209 Snubbull
It loathes being dressed in human clothing. If subjected to such embarrassment, it will attempt to escape and plot revenge on its former owner.
#210 Granbull
It bites on and shakes viciously. It is responsible for nearly 60% of all dog-related fatalities each year.
#211 Qwilfish
Its venomous stings can kill a Wailord. It favors the shallow waters near tropical resorts.
#212 Scizor
Its pincers can crush skulls. The strange marks glow ominously before it deals the killing blow.
#213 Shuckle
An intelligent fungus that secretes enzymes into its shell to digest food. It is highly dangerous to humans but may be dealt with by dropping it into a pool of water- the haplessly slow Shuckle will soon drown.
#214 Heracross
Males fight each other with their enormous horns. The winner disembowels and eats the loser, sometimes dipping it in honey.
#215 Sneasel
It usually feeds on defenseless young. Most often it robs the eggs of birds such as Pidgey and Taillow, but it may steal into human cradles in rural villages as well.
#216 Teddiursa
It is an opportunistic omnivore. It acts like a cute teddy bear to get close to unprotected children.
#217 Ursaring
While the bulk of its diet is herbivorous, it will readily hunt those who enter its territory. It can outrun a Rapidash for up to two miles.
#218 Slugma
The magma pulsing through its circulatory system is hot enough to break even strong ionic bonds. If exposed to sodium chloride, the liquid salt will pervade its body and kill it.
#219 Magcargo
Its body is hotter than some stars. Standing near it will melt your face off through convection.
#220 Swinub
Masses of Swinub huddle together for warmth in frozen mountain caves. If disturbed, they will swarm and suffocate the intruder.
#221 Piloswine
It charges surprisingly fast when disturbed by a loud sound. Its tusks gore hundreds of hikers each year in northern Sinnoh.
#222 Corsola
Increased levels of carbon dioxide in the oceans have led to acidification, destroying the exoskeletons of Corsola. Pacifidlog Town, which is built on a Corsola colony, is likely to sink into the sea within thirty years.
#223 Remoraid
It attaches itself to a Mantine and eats the leftover scraps and feces of its host. If it does not receive enough to eat, it will start sucking the Mantine's blood.
#224 Octillery
It hides in rock crevices, pulling unsuspecting divers in with its powerful tentacles. Reports from the Caribbean speak of giant Octillery lurking in the blue holes which feed exclusively on human flesh.
#225 Delibird
It constantly delivers food to its hungry chicks. Be careful or you may wind up in its sack!
