1. get a ghastly 2. raise into a haunter
here's the tricky part...
TRADE IT
after you trade it will imediatly evolve
then just trade it back and you'll have it.
hope i helped
you can't catch a gengar. you catch a haunter then trade it so it evolves. make sure its not holding an everstone. ;)
i have two Pokemon from Pokemon fire red/leaf green and togepi/togetic and gengar can learn metronome
You can't. In order to obtain a Gengar, you must trade a Haunter from another game to Leaf Green. When traded, Haunter evolves into Gengar. It's the only way. Good luck!
Ghastly evolves into Haunter at level 25, and Haunter evolves into Gengar when traded.
You'll have to trade it from Fire red or Leaf green versionAlthough its 1st and 2nd evolutionary forms arecatchable; Gengar, unfortunately, are not found in the wild. You can only get them by trading a Haunter from Fire Red or Leaf Green, or through a GameShark/Action Replay code.
Weedle/Kakuna, Sandshrew/Sandslash, Vulpix, Magby and Haunter/Gengar plus you can also Pal Park any Pokémon that's in Leaf Green as well.
you don't but you can put in fire red, leaf green, ruby, sapphire, and emerald and go in the red eyed room in the old chateau.
You can get Pollywhirl in Pokemon Leaf Green in Virdian City.
Both ghost-type and dark-type Pokemon are super-effective against any ghost-types.
The Pokemon you can get in fire red and not leaf green are Electabuzz and Scyther.
you can't get mamoswine in Pokemon leaf green because it doesn't exist in leaf green
there is no Pokemon green leaf and Pokemon leaf green you can't only diamond pearl platinum heartgold soulsilver and maybe black and white
