Disclaimer: If I owned Pokémon, there would be a lot more ways to get a Game Over than having all your party faint. But I don't!

#626 Bouffalant

They were shipped to the frontier to fight against native tribes. Their horns contain nerve tissue, so the process of ringing them to show ownership was extremely painful.

#627 Rufflet

It is often malformed due to DDT poisoning its egg. It is abandoned by its parents after a few weeks to force it to prove its bravery.

#628 Braviary

They constantly provoke territorial wars with other birds. They are kept in tiny cages in government offices as the national bird of Unova, but are rarely fed.

#629 Vullaby

The fluids in its amniotic sac are very sticky, keeping the egg glued to its body. This limits its mobility and makes it easy prey for unrelated Mandibuzz adults.

#630 Mandibuzz

It is an accipitrid rather than a cathartid, so its talons cannot grasp prey- it must scavenge. It only decorates its body with the bones of human women.

#631 Heatmor

Its "tongue" is made of manipulated fire, so it lacks taste buds. It must be educated to eat Durant or it will simply starve to death since it cannot taste.

#632 Durant

They attack in single-minded swarms. All Durant worldwide are fairly closely related and can combine to form one mega-colony to attack human settlements.

#633 Deino

It bites to learn about the world around it. Although its bite is not venomous, its saliva contains so many bacteria that death will usually result anyway.

#634 Zweilous

It cannot see, which somewhat limits its ability to find food. However, its advanced olfaction and infrared sensing mitigate this problem, especially when it hunts those unaccustomed to caves.

#635 Hydreigon

One of the fighting heads won. However, it still eats for two.

#636 Larvesta

It was born in a fiery nest. It spreads ashes around as it travels, igniting everything in its path.

#637 Volcarona

A monstrous moth that speaks through two telepathic Clefairy. It was revered in ancient times not only as a sun god but as a destroyer.

#638 Cobalion

It becomes drunk and seeks to transfer its pain to others. If it sees a person shirk his duties, it will impale him with its metal horns.

#639 Terrakion

It grows sullen after it eats too much and seeks to punish others for not feeding it. If it sees a person withdraw from society, it will crush him under a rockslide.

#640 Virizion

It feels depressed when Pokémon die and seeks to avenge them. If it sees a person litter in a forest, it will chop him to bits with the plants growing from its body.

#641 Tornadus

A man lucky enough to find it under his power wished for a million more wishes. In response, it blew away his family in a hurricane.

#642 Thundurus

A man lucky enough to capture one wished to revive his dead wife. In response, it electrocuted his family in a thunderstorm.

#643 Reshiram

A heavenly creature that attends the divine court. It descends to Earth in all-consuming fire as an avenging angel who seeks the fallen.

#644 Zekrom

A child of the unholy union between fallen angels and human women. It summons storms to destroy members of the heavenly host.

#645 Landorus

A woman lucky enough to trick one into serving her wished to be the master of all living creatures. In response, it drowned her family in a monsoon.

#646 Kyurem

An ancient, long-dead ancestor of the angels. It was sent to Earth on an asteroid to consume humans for their sins.

#647 Keldeo

It turns angry when filled with youthful zeal. If it sees a person withhold his laughter, it will plunge him into a nearby body of water and drown him.

#648 Meloetta

Its song drives women who hear it into an ecstatic saturnalia. It leads groups of them to rip apart men who have spurned them.

#649 Genesect

It was the most dangerous and uncontrollable predator of all time. After it has been reborn with genetic modifications as the ultimate warrior, do not expect to continue your journey as a Trainer for much longer.
