Everybody here has at least dreamt of a world where Pokemon actually exist, but there are quite a few that shouldn't exist if the chance were ever to come.
Magcargo: Its body temperature is 18,000 degrees Fahrenheit, which is over twice as hot as the surface of the sun.
Shedninja: If you look at the spot on its back, it consumes your soul.
Houndoom: The burns it causes result in literal lifelong pain and agony.
Litwick and Lampent: It pretends to lead people to safety, but secretly uses its flame to consume their souls, and hangs around hospitals or other places where death will soon occur to obtain more souls for fuel.
Drifloon: They kidnap children and take them to hell.
Lugia: The flapping of its wings causes storms that last 40 days and 40 nights.
Entei: Its barking alone can cause volcanoes to erupt.
Dusclops: Its essentially a walking black hole. When something goes in, it never comes back out.
Haunter: They hide in the shadows and kill whoever comes near them.
Grimer and Muk: Wherever they go, they trail toxic sludge which makes more of them and can leave entire areas uninhabitable for years.
Snorlax: They fall asleep in the middle of roads and bridges, which is both an inconvenience for casual drivers but a real danger for emergency vehicles like police cars, ambulances, and fire trucks.
Guzzlord: It devours whole buildings and mountains, and like Dusclops, whatever it eats never comes back out.
That's it from me, now it's your turn.
