#176 Togetic
It seeks to bring happiness to mankind. It will assist the depressed in committing suicide.
#177 Natu
They inhabit rainforest ruins, sometimes to the point of infestation. If they see humans enter, they will frantically warn them to leave by flapping their wings and projecting telepathic images of death.
#178 Xatu
Most Xatu look only a few years at most into the future. All who have prophesied further than a decade have ended up psychically imploding their own minds to kill themselves.
#179 Mareep
It is commonly farmed, particularly in the mountains of Johto. Its meat has a metallic taste reminiscent of blood that many find appealing.
#180 Flaaffy
Its wool is fashioned into expensive and warm jackets. However, the static electricity generated by the fabric rubbing together may be enough to electrocute the wearer to death.
#181 Ampharos
Its preferred habitat is the high crags of southern Johto's coast. Unfortunately, sailors mistake its tail beacon for a lighthouse and crash into the rocks below.
#182 Bellossom
It lives on tropical beaches, often in prime tourist areas. Its pollen puts nearby people into a deep sleep, causing them to drift off into the sea when the tide rises.
#183 Marill
Its thinly skinned tail buoy keeps it afloat. If the organ is punctured by a Goldeen or other predator, it will drown.
#184 Azumarill
Its flesh is favored by high-end Johto restaurants. Since it can only hear clearly underwater, it can be grabbed and strangled easily when it comes up for air.
#185 Sudowoodo
Travelers in rural Johto are advised to spray trees they must pass close by with water. Otherwise, they may be strangled and eaten by a camouflaged Sudowoodo.
#186 Politoed
Courting males sing enchanting songs during the summertime. Do not listen too long, or the vibrations will give you a heart attack.
#187 Hoppip
Nets are strung up in valleys to catch them on the wind. They are then thrown alive into vats of yeast in order to brew beer.
#188 Skiploom
They float in huge groups over the ocean. The toxic powders they drop into the ocean kill all nearby species, allowing them to carry the dead creatures onto land and gorge themselves.
#189 Jumpluff
The toxic powder it drops looks like snow. Children who run out to catch some on their tongue scream for only a few minutes before dying.
#190 Aipom
The fruit it eats contains mind-altering chemicals that give it a perpetual grin. Captive Aipom are desperate to escape and get another taste.
#191 Sunkern
A defenseless seed that rarely survives to grow into a plant. It is roasted alive and served at baseball games.
#192 Sunflora
It turns constantly to face the sun. If kept in a completely dark environment, its head will eventually fall off.
#193 Yanma
It can generate shock waves that shatter windows. It does this intentionally to enter houses in search of prey.
#194 Wooper
It cannot close its eyes, only cover them with film. If taught to use a punching attack, it will send signals to an atrophied arm located in its chest and develop it rapidly, causing extreme pain.
#195 Quagsire
Most Quagsire have a cheerful and insouciant disposition. However, those found near the Ruins of Alph are fearful and depressive.
#196 Espeon
It has telepathic and precognitive abilities. These powers developed after scientists tampered with an Eevee's brain cells.
#197 Umbreon
Its rings glow eerily in the moonlight, healing all its wounds. This process is extremely painful, causing it to shriek nightmarishly all night long.
#198 Murkrow
Its presence has been determined to have a statistically significant effect on probability. The bad luck it brings its victims eventually results in their death, allowing it to feast on the carrion.
#199 Slowking
The neurotoxins the Shellder injects into its brain increase its intellect tremendously. However, they eventually drive it insane.
#200 Misdreavus
It bites off strands of human hair. After taking the locks back to its den, it uses them to gain magical control over the person.
