Unown (?)
you cant
All you have to do is fill the Pokedex completeley. There are some pokemon which you will have to trade from white but you can do it.
These Pokemon can be found in the tanoby chambers on seven island these Pokemon look like the alphabet if you look carefully in the monean and viapois chamber you can find an exclamation mark and question mark unown.
if you catch all 28 unknown, including the exclamation mark and question mark unowns, the unowns will spell the alphabet and question & exclamation mark unowns i really dont know what they do.
Erm........do you mean (Five question mark) Glitch Pokemon?
Unown (?)
you cant
Yes, there is. As a glitch in the generation 3 games of Pokemon, a glitch Pokemon appears as a question mark. Its image can be viewed in the related link below. In any game with unown, there is a question mark shaped unown, and is not a glitch. You must capture the other 26 unown before getting this question mark shaped unown (along with an exclamation mark unown).
What base (question mark)
If it shows up as a question mark it is the missind Pokemon, Missingo. Missingo really isn't a Pokemon but it is a glitch Pokemon.
If you are talking about the question marks in the pokedex, then you have to catch them, trade them, or find an action replay code. If you need more help on where to find them, go to www.serebii.net.
