Well it depends what legendary you mean. There are a lot and it would be hard to tell where they all are.
I put a link to guide on all the legendary pokemon in Pokemon Black in the related links.
You will be able to catch the 3 currently unobtainable legendary Pokemon, Keldeo, Meloetta, and Genesect. Catch 'em all!
defeat all gyms,elite 4 and champion of that region to catch legendary pokemon
no
Moltres is a legendary pokemon all legendary pokemon are harder to capture.
you can start over
a vagina cold
You can catch Lugia, and evolve Growlithe into Aracanine, which is not considered legendary, but literally has the title of Legendary Pokemon. Hope this helps!
Just catch them,you dummy!
catch them
In Pokemon black/white you must have all the badges and catch tornadus/thundurus and get someone to trade the other legendary( ex. if you have white, get someone to trade for a tornadus). Than goto the shrine with both the legendary pokemon in your backpack and landorus will come out of the sky. Save then fight. Source: me got him a long time ago.
