There is one 'Unown' for every letter of the alphabet, so that means 26, but, once you have caught all of them you must talk to the Ruin Maniac and he will set you challenges, so do them and eventually he will dig so deep into the cave that he will pop out on the other end of the Solaceon Ruins and you can catch the unowns ? and !.
i think so but im not sure i caught all of them in the cave
nothing happens
you can get seals with the unknows
they can be bought at a market i think. also if you show unknows to a kid in the town near the unknown ruins, he gives you seals of the alaphabet (inc ! and ?)
It is said that when you get all unknown you will get something i think a pokemon but i am not sure
you have to catch all of the pokemon in diamond or SEE all of the pokemon
The only way you can see all the Pokemon on diamond is by going into the GTS and global trade different Pokemon.
All of what?
You can get Pokemon diamond for PC from www.roms.zophar.net/Nintendo-ds/all
you've gotta be crazy if you think someones gonna write all the Pokemon you can catch in diamond
Spell the word "mystic" with the unknown Pokemon. Then go back to professor oak if you have 60 Pokemon at least. He should give you a mystic ticket.
no way
