As you keep catching unknowns more of your POkedex is unlocked as you keep going back to the scientist for more updates(Not new pokemon, just new letters/unknown types) But nothing haapnes when you catch them all, except for fully completeing the Unknown part of your pokedex.
Kudos to whoever gets that far, it takes a lot of work.
nothing does.
nothing..
The tunnel on top the ruins is accessible.The tunnel is where you catch the ? and ! Unown.
Nothing happens if the unown you catch can be arranged to spell water.
In Pokemon gold/silver/crystal/heartgold/soulsilver you catch them at the Ruins Of Alph outsid violet! :D
I'm not sure if Crystal is the same (it should be), but in Silver and Gold versions Unown can be found in the Ruins of Alph.
Catching...
You're pathetic.
You can catch unown in the Solaceon ruins on the right of Solaceon town
you catch unowns just to fill out your unown notes. nothing happens when you catch all 28 of them including ! and ?
Yes, you can catch Unown in Diamond. They are in the Solaceon Ruins in the Sinnoh region. Different forms of Unown will appear in the different rooms.
If you catch 26 Unown in Pokemon Diamond, go to Ruin Maniac Cave. He will be waiting inside for you. You can catch Hippopatos in the cave, along with Geodude. Go to the end of the cave where there is another entrance. Go through, and when you get inside, you will see a writing on the wall. It says, "?!" Those two Unown are in there. Capture them. You now have all the Unown.
Nothing happens, except the fact that you have many Unowns. ~Katie
Nothing really; just some information for the unown report... and the pleasure you get!
