No.
Trade it over from gold, or silver version.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
yes it can. its the same with red/blue/yellow being able to trade with gold/silver
Can u trade pokemon between gold version and leaf green
No, you cannot trade between the two different versions because the Pokemon are different or the Pokemon know different moves that are not in red version. When they re-make gold and silver for DS there may be some way to trade between Pokemon fire red and leafgreen to the new gold and silver but I doubt it.
no you can not trade bettween those games
You have to trade from Firered or Leafgreen version.
Leafgreen can only trade between firered, ruby, sapphire, emerald, Pokemon colosseum, Pokemon xd gale of darkness, and migrate with diamond, pearl, platinum, heartgold and soulsilver it cannot trade with the original silver.
No it's not possible. No method of trading where designed to trade between these games.
Emerald can trade with Leaf Green but not Pokemon Red
You trade between two games, gold, silver, or crystal.
No, because the Blue version wouldn't recognze it(I think). You can't trade from silver,gold, or crystal to anything but red,yellow,blue because new games have different Pokemon not known to old games.
