Game Freak is actually game freaks! Some Pokemon's pokedex entry is very odd and strange or even can scare a child to play the game! Here is some freaky examples I've found when playing:
Pokemon Firered:
Raichu - ''
Its electric charges can reach even 100,000 volts. Careless contact can cause even an Indian elephant to faint.
'' <--- Eh what?
Parasect - ''
It scatters toxic spores from the mushroom cap. In China, the spores are used as herbal medicine.
'' <--- Why is China involved in a fantasy world?
Xatu - ''
In South America, it is said that its right eye sees the future and its left eye views the past.
'' <--- Oh really?
Pokemon Sapphire:
Cacturne - ''
If a traveler is going through a desert in the thick of night, CACTURNE will follow in a ragtag group. The POKéMON are biding their time, waiting for the traveler to tire and become incapable of moving.
'' <--- That's how it pks humans!
Gorebyss - ''
Although GOREBYSS is the very picture of elegance and beauty while swimming, it is also cruel. When it spots prey, this POKéMON inserts its thin mouth into the prey's body and drains the prey of its body fluids.
'' <--- Watch out, summer swimmers!
Pokemon X:
Snubbull - ''
It has an active, playful nature. Many women like to frolic with it because of its affectionate ways.
'' <--- The new playboy eh?
Pokemon Sun:
Drifloon - ''
Stories go that it grabs the hands of small children and drags them away to the afterlife. It dislikes heavy children.
'' <--- Racist!
Pokemon Moon:
Bewear - ''
This Pokémon has the habit of hugging its companions. Many Trainers have left this world after their spines were squashed by its hug.
'' <--- Beware! You've been warned!
