Yes you can trade leafgreen version Pokemon to another leafgreen version.
after defeating lance go to the whirl islands and he'll be there
Not in Pokemon leafgreen only in Pokemon Firered never ever in Pokemon leafgreen And in Pokemon firered it is rare in power plant not available in Pokemon leafgreen?
well you can mix up luigia and Ho-Ho
You can find Luigia at the Whirl Islands, you have to go quite deep.
when you encounter him hes lvl. 50 and hes psychic/flying. so it depends on the pokemon you use.
you should go to gamestop
On Pokemon Pearl's title screen, if the Pokemon LeafGreen game is in the GBA slot, click on "Transfer From LeafGreen" and you can choose six Pokemon from LeafGreen to transfer to Pearl, but be careful-you can't trade them back.
