You can find legendary Pokemon in Pokemon battle quest in the pokeshop.
no
you cant if its a regular Pokemon the original answerer is right but if it's a ditto and you are facing a legendary you can transform into it for the length of the battle or until ditto/legendary Pokemon faints if it faints during the battle.
All legendary

A person can find legendary Pokemon in Pokemon Battle Quest by searching the map and battling other trainers. It is also important to have upgraded Pokeballs.
stupid head
If you count sudowoodo as a legendary then yes
you need action replay DS. theres a code in a website that says rebattle then the list says all of the legendary pokemon.
there is no disc its just a chip u put in the ds to catch legendary Pokemon (dialga palkia giratina etc) or normal Pokemon. you have to type in a code for the Pokemon so u can battle it
if you have Pokemon pearl or diamond you can connect 'em up and send legendarys from your ds to Pokemon battle revolution. :)
there are cheats called re-battle... which lets you re-battle any legendary pokemon. Just search with google or something for the code
