First solve all of the puzzles in the Monean Temple. Then Unown's will be released so you can capture them.
Unown in "A" form and in "?" form
you can find unown I in Weepth chamber, unown ! in Viapois chamber, and unown ? in Monean chamber.
There are no legendaries in any of the Tanoby Chambers. Once the Tanoby Key in Sevault Canyon is completed, the Unown appear inside the ruins. The Monean Chamber is home to two species, Unown A - 99% Unown ? - 1%
Some unown can be found in the tanoby chambers although leafgreen can get some firered doesn't so trade the leafgreen unowns to firered to get them all. Psst if you look very hard in the viapois and monean chamber you can find two secret unown: A exclamation point and question mark.
i don't know about a mystical pokemon, but if you solve the puzzle in Tanoby Key (which is the cave in seavault canyon) Unown appear in the Monean ruin. Solve the puzzle in Tanoby Key by putting all the boulders in the holes.
Nothing you just catch them that's it. Psst in the monean and viapois chamber you can rarely find a question and exclamation mark unown.
