In Nintendo DS and Game boy Advanced they are caught by using masterballs. You can find masterballs in the tall grass as a hidden item or go to the Pokemart and buy some. First, say if you ran into Rotom you'll need to use dark-type attacks but don't defeat them just weaken them then throw a master ball at them. That is how you catch ledgendary Pokemon.
Apparently, the first Pokemon Bill caught was Abra. If you find the ruby and sapphire for Ceilo and click A on him afterwards, he will tell you that the first Pokemon Bill caught was Abra. So Bill caught all the pokmeon in alphabetical order. (Except legendarys)
You can't catch any legendarys in Iron Island.
u cant ever get legendarys as starters ever
use strong Pokemon that you trained(not caught directly from the wild)with good movesets. you should have varity of types. good choices for Pokemon are legendarys.
it is a cheat where you can make a certain Pokemon appear in the grass. so far, ive only see one for Pokemon platinum. i caught all the starters and legendarys all shiny
no
