In the games that came before heartgold and soulsilver, I don't believe anything special happens.
In Heartgold and Soulsilver, you can now catch the last 2 unown (the "!" and the "?") in the Hall Of The Ruins Of Alph. Then the scientist that gave you the unown recorder comes out and gives you a pat on the back...
Nothing is known about what happens after achieving capture of all 26 Unknowns. Sorry to disappoint.
There are 26 unknowns out of 486 Pokemon. There are actually 28 with the ! and ? plus the English alphabet and there is 493 not 486 geez Lolz
first of all, there are more than 26 unknown. There are 2 symbol unknown too (i think there's a ! and a ? unknown). Second, there isn't any bonus for catching all te unknowns that i know of except for filling your pokedex, even though you only need one unknown to fill that spot
The alphabet so 26+2 because of the ? and the ! unknowns.
you can't instead after catching all 26 unknown and having them in your PC box go to him and he'll have finished the tunnel go to the end and talk to him, go into the opening and catch the unknowns ? and !
its the way unknowns talk 2 each other. once you solve 1 of the picture puzzles, you will wake up the unknowns, and if you catch all 26,go to the PC in the research place,go back in there, and a celebi shows up.PS if you talk to the unknowns while the radio is on with the weird signal, and talk to them, it will say, a strange sound is coming from UNOWN...
26+ the 2 u find after u catch all 26 The 26 arre all the alphabet unknown and the 2 others are the exclaimation point and question mark unknown. On the other side of Veilstone City, there is another cave go in it an a guy wants to race u to c if you can catch all of the unknown faster than he can build a tunnel, so when you catch the alphabet unknown you talk to him and he takes you to the other 2 unknowns. I think you have to have a heart scale though but im not sure.
Once you catch the 26 letters of the alphabet in Unown, the Maniac Tunnel on Route 214 will be complete, allowing you to catch Unown in '!' and '?' forms. Other than that, nothing else is unlocked.
Different rooms in the Solaceon ruins have different Unowns.
Solve at least one puzzle in the Ruins of Alph. Solve all of the puzzles to make the whole alphabet appear. When you catch those 26 show the nerds in the house and then the ? and ! Unowns appear in the entrance to the big chamber. run around for a bit and they should appear.
you go to the scufic chambers and catch all 28 or 26 im not completely shore
you get celibi
