do you mean catch other peoples' pokemon? you can't.... not even with with a masterball!!!!
No.
nope
You can use a Action Reply codes to catch other trainers pokemon.
YOU CAN'T CATCH OTHER PEOPLES POKÉMON. it's against the pokélaw:)
not only can you not capture other peoples Pokemon, you will throw away a poke ball for nothing!you can only trade for other peoples Pokemon
You can usually catch others Pokemon by using a Master Ball(does not always work)
You can't, it's impossible!!
Not unless you have an action replay plugged into the back of your DS.
You can't if you try to its one pokeball wasted.
no it requires an action replay or any other cheating device to catch other people's Pokemon but i wouldn't recommend it because it can destroy your game
It will not hurt you, but it is a bit of an odd thing to do and remember it is possible to catch STD's from other peoples semen.
I would recommend 900 master balls, all the medicines, and catch other peoples Pokemon.
